His techniques and fighting style usually rely on his immense strength and power, but in tight situations he can lower his power in order to become faster. Additionally, he specialises in brutal fighting. He is quite clever and will often lure his opponents into wasting stamina.
He is depicted as a formidable opponent and far more powerful than any other Chojin; the concept of Chojin Kyodo was introduced specifically to illustrate this point. Buffaloman's Chojin Kyodo is 10,000,000 Power, which is 10 times that of Warsman, previously Kinnikuman's greatest opponent. By the end of the series many Chojin who surpass 10,000,000 Power have appeared, but Buffaloman still boasts of his power and is the only one where it is treated as an advantage.
Despite being a Devil Chojin, he normally fights honourably and shows his opponents respect. During his fight with Kinnikuman his good heart is awakened, and he is revived as a Justice Chojin after his first death.
He is very large and has two curved horns called Long Horns (ロングホーン) on both sides of his head, and has a spike on each knee. He has curly brown hair, with a darker shade of skin and pure white eyes.
Buffaloman was originally a Chojin Power 1,000,000 Power Chojin, who was continually beaten because he lacked skill.  He eventually met and struck a deal with Satan, who granted him more Chojin Power each time he killed another chojin. Eventually he killed so many that his power had climbed to 10,000,000. 
He and his comrades, all known as the Seven Devil Chojin (Springman, Atlantis, Stereo Cassette King, Black Hole, Mister Khamen, and The Mountain), were eventually captured by a grouping of 100,000 Justice Chojin and Space Police and trapped in a Chojin Roach Motel and sent into space.
Harabote reveals that seven chojin were banned from the Olympics, due to their ruthless nature, and these seven Devil Chojin were placed into a floating space prison named a "Roach Motel".  The "Roach Motel" is accidentally opened, when Kinnikuman is thrown straight onto the release mechanism during celebrations of his most recent victory. Buffaloman and the other Devil Chojin arrive at a fan-appreciation day, where Kinnikuman and his friends are celebrating the conclusion of the 21st Chojin Olympics. 
Buffaloman initially attacks Warsman, who attacks him in defence of the children present. He announces that they cannot allow Kinnikuman to call himself "champion", until he had defeated each of the Seven Devil Chojin.  Buffaloman splits Alexandria Meat's body into seven pieces; this forces Kinnikuman to beat them all within 10 days, if he wants to save his friend.  When Kinnikuman is too injured to keep fighting the Seven Devils (after he defeated SteCassette King and Black Hole), his friends step in to take on the remaining Devil Chojin in his place.  Buffaloman is pitted against Warsman. 
In the match, we see Warsman dodging a series of Hurricane Mixers.  On the eleventh try, Buffaloman pierces Warsman's hip, and proceeds to take out a chunk of Warsman's helmet. Warsman tries an arm hold, but Buffaloman breaks free and attempts a knee drop, which is countered by a Jet Liner. Buffaloman is unaffected again, and uses a Long Horn Boomerang.  Warsman follows with a Palo Special, but is thrown off by Buffaloman and damages his legs.  Warsman then destroys his Bear Claws on Buffaloman's horn, when attempting a Screw Driver attack. 
Buffaloman pierces a hole through Warsman's chest, which inspires Warsman to use his own version of the Fire of Inner Strength.  After an exchange of blows, Warsman begins to smoke from his body, and he grows too exhausted to properly continue the match. Warsman attacks with his Bear Claws one last time, and he manages to break off one of Buffaloman's longhorns.  Buffaloman uses a series of Hurricane Mixers to kill Warsman.  He then walks away and leaves Warsman deceased in the ring. 
The final match takes places in the Denen Colosseum. 
Buffaloman faces Kinnikuman in a double match with Springman. There is only one hour left of the deadline, so Kinnikuman only has one hour to save Meat. The stadium is designed as a giant countdown, with bars around the edges that move for each second, and that will destroy pieces of Meat's body at the 30 minutes and 60 minute marks. Just as Kinnikuman is about to fight alone, Mongolman appears to make it a true tag-team match and join Kinnikuman in his fight against Springman and Buffaloman. 
Despite it being called a tag-team match, Buffaloman's attention is focused exclusively on Kinnikuman, while Springman fights against Mongolman.  Mongolman defeats Springman and saves Meat's limb.  Buffaloman is an extremely tough opponent, and - changing colour, as he uses the full force of his 10 million Chojin Power - uses his power to reverse Kinnikuman's techniques, including his trademark finishing move: the Kinniku Buster.  During an exchange of blows, Harabote uncovers information on Buffaloman. 
After Buffaloman helps fix Kinnikuman's mask, he becomes fully possessed by Satan.  When Buffaloman goes beneath the ring, shredding the canvas with his horn, Kinnikuman uses his arm to stop the horn, and tosses him back onto the ring.  Buffaloman loses control of his power when he absorbs Kinnikuman's Fire of Inner Strength.  Buffaloman pierces Kinnikuman's body with his horn, before - overwhelmed by The Fire - the power returns to Kinnikuman and allows him survive. 
Due to the respect Kinnikuman showed him, even though they were mortal enemies, Buffaloman changes sides at the end of the match. He cries out the key that will free Meat's head, which allows Meat to be saved just before the final countdown.  Buffaloman vows to join the Justice Chojin, if he survives Satan's punishment for defeat.  He s fatally injured by Satan, but - before he dies - he gives up his Chojin Power, bought with the blood of other heroes, to bring back to life Warsman, Robin Mask and Wolfman, who had died fighting his teammates. 
Kinnikuman struggles to make it through a door to the final match, and - at the last moment - Buffaloman uses his high chojin power to keep the door open for him.  When Kinnikuman offers him a seat at the ring-side, on the side of the justice chojin, Buffaloman refuses and joins the devil chojin in the corner of Asuraman.  Asuraman appears to gain the upper-hand, but - in a dispute with Meat - Buffaloman inadvertently gives Kinnikuman inspiration needed to counter-attack. 
He then confronts the Devil Knights leader, General Devil, in order to give Kinnikuman more time to perfect the Kinniku Driver.  He is eventually defeated by Devil Shogun's Hell's Guillotine technique.  During the fight between General Devil and Kinnikuman, General Devil begins to revive the Devil Knights and absorb them to become more powerful, but Buffaloman puts on General Devil's mask and fights them off, which gives Kinnikuman the chance he needed to defeat Shogun with the Kinniku Driver. 
On top of this mountain, the Universal Chojin Tag Team trophy appears. Underneath, there appears a series of rings that allow for eight tag-teams to compete. Buffaloman - along with the other justice chojin - goes to Kourakuen Hall to discuss the situation. Buffaloman refuses to team up with Kinnikuman and leaves.  He sends a letter to Mongolman, asking him to join him as a new tag-team. 
Buffaloman and Mongolman forms the 20 Million Powers.  The name of their combo comes from Buffaloman's 10,000,000 power and Mongolman's 10,000,000 techniques (10 Million + 10 Million). In the first-round match-ups, the teams are required to navigate a labyrinth to be matched against their opponents, and the 20 Million Powers are matched against the Most Dangerous Combo.  Just as the 20 Million Powers and Most Dangerous Combo are about to begin their fight, during the Dream Chojin Tag Arc, the Killer Game Combo arrive.  This leads to the Killer Game Combo defeating the Most Dangerous Combo. 
Brocken Jr. does not want his loss to count for nothing, so - to allow the 20 Million Powers to win - he challenges Buffaloman and allows himself to be pinned; this allows 20 Million Powers to officially win the match.  This technical win allows the 20 Million Powers to advance to the next round, but the 20 Million Powers attack the Killer Game Combo for their intrusion. Buffaloman uses a feint against Screw Kid, but Mongolman - using the distraction to attack - injures his leg in the process. 
Buffaloman is then struck by Kendaman, and the Killer Game Combo ask for formal permission to enter the tournament in the place of the Most Dangerous Combo. The 20 Million Powers declare that they will earn their place in the next round by first defeating the Killer Game Combo. The match began with a fierce one-on-one battle between Buffaloman and Kendaman, but Buffaloman tries a Hurricane Mixer on Kendaman, but it fails.  Buffaloman is then caught in a Scorpion Defence by Kendaman. 
He proceeds to break off his Long Horn and breaks the glass of the War-Cube, but is then attacked by a Hell's Screwdriver, which is only stopped by the thrown hair of Mongolman. Buffaloman counters with a powered-up Hurricane Mixer.  Fearing the punishment that comes from failing their superiors, Screw Kid and Kendaman begin to use dirty tactics.  At this point Neptuneman and Big the Budo reveal themselves, and Kendaman and Screw Kid abandon the match to attack them, and the 20 Million Powers win by default, as the Killer Game Combo are killed by the Hell Missionaries outside of the ring. 
During the match-up lottery for the semi-final placements, the 20 Million Powers are matched with the Hell Missionaries.  The first match is between the Muscle Brothers and the Stray Devil Chojin Combo, and the 20 Million Powers stay at the edge of the ring to act as spotters.  At the end of the match, after the defeat of the Stray Devil Chojin Combo, the Hell Missionaries attack Sunshine, only to be stopped by the 20 Million Powers.  They then allow the Hell Missionaries to attack, as the dolls - created by the Stray Devil Chojin to steal the justice chojin Friendship Power scatter, and thus creates animosity between the justice chojin. 
The semi-final match against the Hell Missionaries is a simple barbed-wire cage match, but also a mask-removal death-match in which Mongolman must bet his mask. Buffaloman is thrown into the barbed wire by Neptuneman, who then switches with Mongolman, who is at a disadvantage from being unable to use the rope for his techniques. After being thrown into the screen cage, Mongolman rebounds with a kick. 
After a series of blows, the 20 Million Powers seem to have the upper hand.  Mongolman begins to suffer flashbacks within the ring, as the cage reminds him of his match against Warsman, and Buffaloman is unable to tag in, as both of the Hell Missionaries attack him. The spirit of Warsman helps Mongolman.  Buffaloman is tagged in and uses a Buffalo Avalanche Drop.  He proceeds to attach his Long Horn, and uses a Hurricane Heat. Mongolman is tagged into the match, but subject to a Cross Bomber. 
Neptuneman uses his Magnet Power in retaliation.  This heals the wounds of the Hell's Missionaries, and they try continuously to attack with Cross Bombers attacks, only to fail. Due to the Iron Sweat on Mongolman and Buffaloman, they are dragged towards the Hell Missionaries by their magnet power, and they almost defeat the 20 Million Powers with a Magnetic Storm Driver.  The 20 Million Powers are then further attacked by a magnetic suplex.  They are soon entangled in the magnetic barbed wires, as they regain their Friendship Power, and the Justice Chojin regain their power of friendship overall. 
The iron sweat breaks from Mongoman and Buffaloman, and Buffaloman uses his Longhorn Train.  This increases the power of the Hell's Missionaries, who use a Silhouette Body Press, and - after a series of blows - are thrown from the war-cube. The Hell's Missionaries summon thunder to increase their electrical power.  Their Lightning Sabre attack renders Buffaloman and Ramenman immobile, and Buffaloman uses a fragment of Iron Sweat to draw Neptuneman away from Mongolman. 
Buffaloman collapses against the mat, defeated by the Light Sabres. 
Mongolman carries Buffaloman on his back, as they try again for a Longhorn Train, but they are defeated by a Magnetic Storm Crash.  Once Ramenman is defeated, Buffaloman is rushed to hospital alongside Kinnikuman and Ramenman.  At hospital, Doctor Bombe removes Buffaloman's horn in order to save Kinnikuman's arm, even knowing it would result in Buffaloman's death, but the tears in Buffaloman's eyes mark his consent to the procedure. 
This story covered the formation of Kinnikuman Soldier's team in detail. Brocken Jr. and Buffaloman want to join Soldier's team, but Asuraman and The Ninja aren't on board with that idea. According to Asuraman, Buffaloman is too easily swayed by his emotions, which is why he never became a Devil Knight despite having exceptional talent. 
Kinnikuman Soldier shows up and interrupted Asuraman and The Ninja's departure. In response, The Ninja attempted to read Kinnikuman Soldier's mind with his Expose the Heart jutsu, but there's nothing to read. Unlike the other Fated Princes, Soldier has no ambition to destroy his opponents and take over the throne. 
Asuraman gets into a fight against Soldier, but Soldier easily fends him off. Soldier even escaped the Asura Buster in a similar fashion to Kinnikuman and counters with a Dragon Cube Suplex. Buffaloman deduces why Soldier would pick those four. Pride is their main characteristic. According to Asuraman, "all four chojin are bull headed guys who won't listen to anyone". 
Asuraman asks if Soldier is a fake Soldier and Soldier confirms this theory. He ambushed the real Soldier's team while they were training near Mt. Fuji and stole the real Soldier's mask. The fake Soldier explains that he joined the tournament because the Friendship Power the Justice Chojin use is a sham and that the pride that they share can bring out their true strength. 
Asuraman wants Soldier to prove why this team of outcasts would make an excellent team. Soldier tells him to be silent. A real man would never talk so much. Instead, he'd silently watch the result with his own eyes. Asuraman follows up with his Tornado Hell, but Soldier dodges, causing the building already worn down by the Rolling Cube Suplex to collapse on top of them. Soldier heals them all with a Face Flash. With this act, Soldier convinced them to join his team for the upcoming tournament. 
When Kinnikuman's right to the Kinniku Throne was challenged by five pretenders to the throne, Ataru Kinniku forms a team of five people to fight in a tournament to determine who shall be king of Planet Kinniku.  Buffaloman - sans his horns - arrives at the house of Brocken Jr., along with Asuraman and The Ninja. Ataru asks them to join his team, as well as to meet him at Nagoya Castle in three days time, and - during that time - they watch him from a distance to ascertain his character. 
After Ataru defeats Bockman and saves a boy, Buffaloman and the others decide to join his team.  They proceed to enter Nagoya Castle and face against Team Phoenix, as they announce they have formed The Chojin Blood Oath Brigade.  After the defeat of The Ninja and Asuraman, Nagoya and Himeji Castles fly away from their locations and join as one structure. 
In the final match during the semi-finals battle against Team Super Phoenix and Team Soldier (Soldier, Buffaloman, and Brocken) competed in a 6-Man Tag Match against Super Phoenix (Mammothman, and Prisman).  The match takes place in a floating multi-sided ring. Buffaloman, for the most part, fought against Mammothman. Tremendously weaker without his Long Horns, he found himself losing against the nearly unstoppable Mammothman. He was finally able to gain and advantage when Kinnikuman returned the Long Horns used to fix his arm before the Tag match finals. Soon after, Brocken took out Prisman, but then fell into the canyon below and died. Seeing how much Soldier and Buffaloman cared for their fallen comrade convinced Super Phoenix that Soldier wasn't the real Soldier.
As Soldier begins to have his true identity figured out by his own father Mayumi as his long-lost elder son Ataru, the Evil Gods choose to sabotage him to eliminate him and help Phoenix win the tournament. The God of Brutality steals a page from the Muscle Prophecy, a book owned by Kinniku Clan royalty which contains past, present, and even future information on every Chojin ever, as a means to reveal who Soldier is to Super Phoenix. As the God of Brutality attempts to give the page to Super Phoenix via Mammothman, Buffaloman sees a vision of Mayumi in his head, forcing him to take the page to protect it. As the mammoth Chojin prepares to hand it to Phoenix, the bull Chojin performs the Chojin Cross Drop on him, jumping out of the ring and forcing Buffaloman to hold the page in his mouth. As they fall, Mammothman hits Buffaloman with his Nose Fencing technique and retains the page. At the last second, Buffaloman hits Mammothman with a Buffalo Bomb on the roof of the Himeji/Nagoya castle and saves the page again.
The Evil Gods then arrived and began attacking the floating ring in an attempt to take out Ataru. As the ring fell, Buffaloman caught it and held it up. Weakened from the battle with Mammothman, he put on a red headband given to him by the other Justice Chojins and found enough strength to not only hold the ring up longer but also remove his arm guards and toss them up to Ataru. He then pushed it into the air and as it fell again, he jumped up and hit it with a Hurricane Mixer, successfully putting it back in mid-air. Unfortunately, Buffaloman had no more strength and fell into the canyon below. He is revived (along with his teammates) after the tournament by Kinnikuman's Face Flash.
Like all the other Idol Chojin, Buffaloman was sent off to his home of Spain by Harabote so he could be placed in Medical Suspension, to help him recover from his many injuries from matches past.
However, when he finished his Medical Suspension and made his return while the Seven Devil Chojin invaded the full-scale tournament going on, he declared he was a Devil Chojin again, renegading on his Idol Chojin friends out of nowhere.
The Seven Devil Chojin reconvene in their base.  Buffaloman returns, where they all decide which of the Perfect Large Numbers they shall do battle against, and Buffaloman decides to fight against Strong the Budo, due to the fact that whomever fights him will likely lose and he will not sacrifice his teammates. The Mountain refuses to allow this to happen, and offers to sacrifice himself instead, due to the team needing Buffaloman to serve as their leader. He asks only that Buffaloman not avert his gaze during his match. 
After Black Hole's match with Dalmatiman, Buffaloman announces that the Devil Chojin are going to purge all Perfect Chojin for their master, Devil Shogun. During the first stage, he mostly oversees how the Devil Chojin fight the Perfect Chojin.
In a flashback, it's revealed that Buffaloman made the choice to return to the Devil Chojin and fight alongside them, which the Seven Devil Chojin welcomed greatly. But they wouldn't let him join them to fight the Perfect Large Numbers because he was their "ace", their leader and without them, the Seven Devil Chojin couldn't perform at their best.
Diablos vs. John Does
Grim Reaper and Turboman enter with the New Large Numbers. 
Grim Reaper reveals the next location - of the second-stage of the tournament - will be the Saqqara Pyramid, which has been relocated to Japan's Tottori Dunes.  The Grim Reaper lands on the third step, while Turboman takes the fourth step.  The Justice Chojin follow them to the mountain, and Buffaloman is assigned against Turboman, who attacks him with a drop-kick before he can enter the ring. 
He then drags Buffaloman into the ring with a Turboman Stunner.  Turboman punches Buffaloman while he's down, until Buffaloman counters with a headbutt and proceeds to use a back-drop.  It is then that Springman arrives on the fourth step to fight the Grim Reaper.  Grim Reaper begin the match with a Buzzsaw Hat, which cuts Springman's leg as he enters the ring with a jump. 
Grim Reaper throws Springman against the corner-post, but the post goes through Springman's hollow body and allows him to remain unharmed, and a Spring-Body Breaking-Squeeze breaks the corner-post. A Spring Transfer allows him to distract Grim Reaper, whereby he land a drop-kick to the face.  While Turboman and Grim Reaper, struggle in their matches and appear to be losing, Jak Tea fights against Black Hole and creates a strong geyser before he dies.  This creates a crack along the pyramid. 
Turboman frees himself from Buffaloman with a Somersault Kick. He tries a body-press, but Buffaloman catches him and counters with a back-flip. The fifth step finally collapses from the cracks and descends into the fourth step, where the two single matches combine into one tag-match. Turboman gets Buffaloman into a tombstone pile-driver, but - as he prepares for another attack - Springman and Buffaloman combine to use a Chojin Dodgeball.  Springman is chastised for attacking Turboman, who was not his original opponent, as the match rules must abide by those of a single-match (due to the unusual circumstances). 
The two teams agree to form a tag-team match with tag-team rules.
Springman lunges at Turboman, who uses a lariat and a Starter Revolver, but gets his arm caught inside Springma, who retaliates with a Spring Cyclone.  Springman proceeds to use a Killer-Coil Head Attack.  A second attempt at the attack is deflected by Turboman's a back-kick. It nearly knocks Springman out of the ring, until Buffaloman catches him. Turboman charges with a flying-cross, but the Diabolos counter again with a Devil Expander. Buffaloman then bounces off Springman to kick Turboman, who proceeds with a series of blows. Turboman uses a Glove Revolver and a Turbine Chop. 
Buffaloman and Turboman return to their corners, and Turboman tags in Grim Reaper, who spins around on Turboman's head and delivers an Ignition Dress to Buffaloman.  They proceed to use a John Does Arrow.  The Diabolos try another Devil Expander, but Turboman dives through Springman and knocks Buffaloman out of the ring, before hitting him again with another John Does Arrows. A High-Capacity John Does Arrow sends Turboman towards Buffaloman, who manages to catch him and slams him against the wall, which causes the wall to crumble into the shape of a flight of stairs. 
This allows Springman to use a Devil Slinky.  He uses a Spring Body-Breaking Squeeze, which causes Turboman's body to start to glow, as Turboman stores the energy of his opponents. Turboman uses a High-Speed Turbo-Crash, as their two attacks seem to create a stalemate, but soon the release of Turboman's energy causes Springman to harden. He proceeds to stab Springman in his face with Revolver Spikes, and a Revolver Fin causes Springman's body to crash into Buffaloman. 
Springman finds strength to lift Buffaloman, despite his weakened state.  The Diabolos attempt a Long Horn Train, but - when it only glances off Turboman - follow with a Most Super Express.  They follow with a third attack, which against glances off Turboman, but Turboman finds strength to use a Revolver Stud while Springman starts to crumble away. Springman uses all his strength to throw Buffaloman into a Hurricane Mixer, and Buffaloman's horns break through Turboman's Revolver attack and pierce his chest. This leads to Turboman's death, followed by Springman dying within Buffaloman's arms. 
The Grim Reaper proceeds to Turboman's corpse, where he opens Turboman's back and steals his Earth Unit (which allows him to store energy to use against an opponent), and then kicks Turboman's body out of the ring.  The Grim Reaper removes his robe, which he uses to taunt Buffaloman like a matador, and uses a Skeleton Body to avoid being struck with a Hurricane Mixer. The Grim Reaper states that people fall victim to Buffaloman's attack due to fear and fidgety movements, but - knowing no fear - he cannot be hurt.
The Grim Reaper grabs Buffaloman by his horns, before grabbing at his skin and flipping him over, and - in the process - tears chunks of skin from Buffaloman.  The Grim Reaper proceeds to tear off more skin from Buffaloman, and attacks with a Dress Spear, which reveals all the scars on Buffaloman's body from previous matches.  He is eventually countered by Buffaloman's Buffalo Hammer. The Grim Reaper proceeds to capture Buffaloman's legs, as he sets up for a John Does Arrows, before revealing it can double as a solo-technique called the Phantom Canon. This causes Buffaloman's scars to reopen in a bloody manner.
Buffaloman summons his blood back into his body by force of will.  The scars move to Buffaloman's horn and turn it into a Long Horn, before he speeds around the Grim Reaper and lands a series of blows.  The Grim Reaper uses an Ignition Dress, followed by a Thunder Sabre, which pins Buffaloman to the canvas, and the Grim Reaper uses the Earth Unit to absorb power from Buffaloman. The sheer power from Buffaloman causes the Earth Unit to break, and Buffaloman uses a Hurricane Mixer. 
This is followed with a Chojin Cross Slam.  The Diabolos are declared the winners of the match, and Psychoman exposes his chest with the offer that Buffaloman kills him as he sees fit, due to the Perfect Chojin suicide rule and out of respect to Buffaloman as the victor. The Grim Reaper taunts Buffaloman until Buffaloman stabs him through the chest with his horn, and this cements Buffaloman's return to a Devil Chojin, preventing him from going back to his Justice Chojin allies. Psychoman then vanishes.
Buffaloman takes a piece of Springman's body and leaves. 
After the Perfect Origin hit the scene, and Grim Reaper reveals himself to be Psychoman, Buffaloman decides to make up for letting him escape alive, but Devil Knight Planetman beats Buffaloman to fighting Psychoman. Buffaloman mostly observes while the Devil Knights take on the Perfect Origin.
Buffaloman vs. Ganman
The fight takes place on the first ring of Yggdrasil. 
They begin by clashing horns in a rapid succession, before Ganman slams Buffaloman's head onto the corner-post with a bulldog headlock.  Ganman attempts to ram into Buffaloman, but Buffaloman counters with a preemptive kick, and attempts a body-press, which is caught by Ganman in turn.  He throws Buffaloman down, before they lock hands centre of the ring, and Ganman attempts a double over-hook suplex; which prompts Buffaloman to state that he cannot lose, as he must avenge Sneagator.
Buffaloman extends one horn, and uses it to pierce into Ganman's right shoulder.  This is followed by a Hurricane Devil Sword, as well as a Buffalo Hammer, until Ganman throws Buffaloman out of the ring and forces him to prevent his fall by drilling into the stone ring.  Buffaloman drills a tunnel under the ring, which allows him to pierce his horn through the surface for a Devil Shark manoeuvre. It is impossible for Ganman to "read" Buffaloman's moves while he is underground, and Buffaloman knocks him down by targeting his legs.
Ganman begins to dodge the horn by sensing Buffaloman's breathing, and catches the horn in his hands, which he uses to drag Buffaloman out of the ring, before using Elk Horn Scissors. He slams Buffaloman onto the ring, which reduces the size of his horn, and Ganman shines a light down on Buffaloman with his cyclops eye.  Buffaloman attempts a Hurricane Mixer, but Ganman catches him by his horns and proceeds to use a brain-buster.  It is revealed Buffaloman is holding back his power, and Kinnikuman and General Devil convince him to use his full power once more.  Buffaloman breaks out of a Canadian Back-Breaker. 
He uses a Reverse Suplex, before struggling evenly with Ganman in the middle of the ring. The two engage in a series of even blows, but the scars on Buffaloman start to reopen as he gains back the Friendship Power of the Justice Chojin, and - after an equal battle - Ganman breaks off one of Buffaloman's horns.  Ganman gains the upper-hand, after a series of carefully aimed blows, until Buffaloman punches his own eye so that he is left with one working eye (just like Ganman) in order to create a 'fair' fight. 
They lock together evenly again in the ring, until Buffaloman dares Ganman to use his eye power on Chojin Enma.  This provokes Ganman to use an Elk Horn Compressor, as he states he will not use his eye power on Chojin Enma due to having faith in him as a person.  He follows with an Elk Horn Tempest, but - as the throws Buffaloman - Buffaloman uses his one remaining horn to swing on the corner-post. Buffaloman builds up speed by moving post to post, and uses a new finishing move: Hurricane Giga Blaster. 
This completely destroys Ganman's horns.  Ganman reveals he has remembered Buffaloman's name, which proves he considers Buffaloman a worthy adversary due to how he forgets all other opponents' names, and hands him his dumbbell. This kills Ganman, who dies upon the canvas. 
Buffaloman meets with Meat and goes with him to check a disturbance. He collapses when Alexandria Meat is taken by six tendrils, much like what happened to him 36 years ago, and the six people reveal themselves to be the ultimate Zangyaku Chojin: the Demon Seeds.  Buffaloman cries to see that the new generation cannot enter the General Palast. 
He stabs himself in the chest with a jagged piece of rock, and tears open the wound to accept the General Stone and reaffirms his pact with Satan.  He uses his newfound powers to open a hole in the barrier, but only one chojin can pass through as his strength is not enough for more. The barrier closes just after Mantaro Kinniku enters, trapping them both inside, but also cutting off Buffaloman's horn in the process. 
Buffaloman tosses away the General stone, only to be carried - in his weak state - by Mantaro.  Mantaro is forced to choose an opponent, but The Constellation attacks before the match, and Buffaloman blocks an arrow aimed at Mantaro with his body in defence of his ex-pupil.  The Constellation pushes the arrow further into the wound and then proceeds to break his arm, but Buffaloman counters with his Hurricane Mixer. The Constellation uses a Suplex, which smashes Buffaloman's head against the concrete floor and cracks open his skull, incapacitating him. 
Mantaro struggles to gain an advantage, but Buffaloman's advice helps him to counter.  The Constellation uses a broken post of the ring to attack Buffaloman, so as to stop his invaluable advice, and it strikes Buffaloman on the forehead and knocks him unconscious.  He regains consciousness just long enough to offer Mantaro further encouragement, before he faints once more.  Mantaro tries to carry Buffaloman to safety, but - due to his injuries - passes out in the central chamber and collapses next to Buffaloman, at which point the B-Evolutions arrive. 
Buffaloman appears late into this arc, as he participates in the tournament at Kourakuen Stadium.  He is featured alongside Mongolman (Ramenman) as part of the 20 Million Powers; despite his missing horns, from the match three days ago in his timeline, Buffaloman seeks to distract the New Generation (to which he sees as the villains).  Buffaloman chastises Robin Mask for helping Chaos Avenir, as he believes they are responsible for Alisa Mackintosh's accident.

- Theme Song: "Devil Buffalo" (悪魔の猛牛, Devil no Mōgyū) by Takayuki Miyauchi
- In his match with General Devil in the manga, Buffaloman removes a wig from his head to reveal a bald, devil-like scalp. The wig removing scene is supposed to show that Buffaloman had shaved his head in contrition for his deeds as an Devil Chojin, and that he had been concealing that he had been a Justice Chojin all along during the Golden Mask Arc. But even some Japanese readers found this confusing and thus this was totally dropped in the anime.
- Buffaloman appears in the Kinnikuman chapter of Super Kochikame, in which he is arrested by Nakagawa for weight training at a Shinto shrine.
- In Mattel's M.U.S.C.L.E. toyline, Buffaloman was renamed Terri-Bull, leader of the villainous Cosmic Crunchers.
- In the Ultimate Muscle American 4Kids dub, he was portrayed with a heavy Russian accent and occasional Russian exclamations like "Bolshevik!", though when Dialbolic impersonates him, he is portrayed with an accent similar to actor, bodybuilder and politician Arnold Schwarzenegger.
- Yudetamago have stated that Buffaloman is modelled after professional wrestler Bruiser Brody. In tribute to the larger Brody's tag team collaboration with the smaller Jimmy Snuka, Buffaloman is paired in tag matches with smaller characters like Springman and Mongolman.
