Scarface, Eskara in the English dub, is a character form Yudetamago's manga and anime series Kinnikuman Nisei (Ultimate Muscle). He is initially a villain belonging to the DMp, one who betrayed Kevin Mask, but later he becomes a strong Seigi Chojin and a leading protagonist.
Scarface is an Akugyo Chojin who poses as a Justice Chojin and enrols in the Hercules Factory after the destruction of the d.M.p Headquarters. He is a master of psychological warfare and is well-studied in Chojin Wrestling techniques and their weaknesses. He has a long-standing relationship with Kevin Mask, having saved his life at one point during their d.M.p training days. After his loss to Kinniku Mantaro, he disappears for a while, returning during the Demon Seed Arc as an Idol Chojin. However, his Akugyo Chojin side resurfaces during the Ultimate Chojin Tag Arc when, while initially joining the Idols to save Kevin Mask, he soon changes his plot to stealing the Completion Bulbs in order to restart the d.M.p.
Although his true name has been revealed to be Mars, he still goes by the name Scarface as an Idol Chojin. He follows a strict diet, often only drinking freshly squeezed juice for a meal the day before a fight. Though he tries to hide it, Scarface is deadly afraid of roller coasters.
Mars joined the d.M.p before Kevin Mask. It was during their training when Kevin nearly lapsed and fell from a precarious point, which would have led to certain death, but - in exchange for one of Robin Mask's secret techniques - Mars saves Kevin Mask and considers this knowledge a debt repaid. When Mantaro Muscle defeated Check Mate the d.M.p base was destroyed and Mars was the only survivor.
After the fall of the d.M.p, Mars altered his identity, calling himself Scarface. He, along with Jade, Clioneman, and Dead Signal defeated Wolfman, Geronimo, Buffaloman, and Jesse Mavia all in under five minutes. In the replacement match he fought and soundly defeated Terry the Kid, utilising psychology about his father Terryman, and nearly killing him with the Ultimate Scar Buster.  After Mantaro defeats Clioneman, Mars goes toe to toe with Jade in a concrete death-match, once again using psychology and turning Jade against Brocken Jr. causing Jade to go into a rage and blindly attack.  Using his Madness Mask he is able to stop the Red Rain of Berlin several times. Jade finally connects with the Red Rain of Berlin, but the move is poorly executed and the wound doesn't even faze Scarface, who taunts him into attacking again. Scarface gets him in a standing shoulder breaker hold and rips his arm off, just as Scarface lifts him on his shoulders. As Jade apologizes Mars taunts him again, saying "Well I got Brocken's permission, that's all I need". 
Scarface jumps skyward and hits Jade with the Ultimate Scar Buster. Afterwards he and Jade shake hands and he wishes him good luck.  Later at a big party for the finals an attendant spills a drink on Scarface and takes him to a changing room.  The waiter then says Scarface's real name, and it turns out to be Kevin Mask in disguise. Locking Mars in the Tower Bridge, he tells Mars to reveal his real name or he (Kevin Mask) would break him in half and take his body to the chairman to do an autopsy. Mars then reveals his true identity by reminiscing with Kevin about the time he saved his life back in the d.M.p. 
Kevin gets lost in thought and his grip on the Tower Bridge loosens, allowing Mars to escape. All the commotion catches the attention of the chairman, and the special ringside enforcers Buffaloman, Wolfman, and Jesse Maivia.  They attempt to go after Kevin but Mars stops them. The next day at the finals Scarface is accompanied to the ring by first term graduates Mercury, Namul, Gyro, and Gorgeous Man (The Adams did not because he said Mantaro was his friend).  As the match got underway Mantaro takes advantage until Scarface knocks him out of the ring (he noticed Mantaro was hopped up on adrenaline and wanted to tire him out). As Mantaro gets back in the ring Scarface takes advantage. He hits Mantaro with a moonsault press but it is ineffective because it just purges Mantaro's system. Mantaro then starts to taunt Scarface by telling him to jump higher and give it all he's got and when Scarface jumps up Mantaro soon follows and locks him in the Kinniku Buster. Scarface pulls his head out and hits Mantaro with a Power Bomb. He says the Kinniku Buster is an incomplete move. Mantaro takes him up in the air again and locks it in tighter but Scarface rotates the move to where Mantaro gets hit with it. 
Kevin Mask shows up with Brocken Jr. and reveals Scarface's true name and that he is a member of the d.M.p. Mars then rips the front emblem open to reveal the d.M.p logo. As he leaves the ring Harabote Muscle tells him to get back in the ring and restart the match, as he is in the Muscle League. Mars jumps back in the ring and jumps up high and uses his Swallow Tail.  Mantaro rolls out of the way. Mars starts to dominate Mantaro, even taking time to mock Harabote Muscle for signing him to the league. He goes to finish Mantaro off with the Swallow Tail but Mantaro evades it. When Mantaro gets up he appears knocked out. Brocken Jr. reveals that Jade is helping him through his skull pendant.  Mantaro manages to hit Mars with Red Rain of Berlin, hurting Mars. Mars knocks Mantaro down, which knocks the pendant off him and off the platform their wrestling on.  Kevin Mask blames himself for his involvement in Mars winning, by teaching him how to reverse the Kinniku Buster for saving him. 
Meat comforts him, stating someone would have figured it out eventually and he did Mantaro a favor by teaching Mars the reversal as Mantaro can prove himself a true champion by coming up with a new finisher. Mars tries to hit the Ultimate Scar Buster to finish the match but, acting on instinct alone, Mantaro reverses it with a wedgie.  Mantaro realise through this he can make a new finisher to win. Eventually, Mantaro comes up with the Muscle Millennium and successfully hits it on the 1st try. The move is lethal, finishing Mars. As he's being taking away on a stretcher Mars tells Kevin he will return one day. 
The Demon Seed reveal there are General Palasts across Japan, and - after using tentacles to kidnap the Army of Idols - take their individual opponents to their specific Palasts.  The General Palast breaks into five pieces, with each Death-Match Room going to the new locations. 
Kevin Mask sees what he assumes to be a Demon Seed before him. He attacks them, only to realise the person is Mars. The two pieces of General Palast – to which Mars and Kevin were dragged – both landed in the same place on Ganryu Island.  Kevin and Mars use their ‘Ultimate Eyes’ to see two Demon Seed standing on Ganryu Island.  The two Palasts form General Rib, and the two remaining Demon Seed create a ring that is covered by a rib-like structure made of stone. It is announced the match will be a tag-team match – Kevin Mask and Mars are rowed to General Rib by Checkmate and Gazelleman respectively. They are due to fight Voltman in the tag-team of The Demolitions.  Kevin and Mars name themselves the Blood Evolutions (Ｂブラッド-エボリューションズ).
They engage in a series of blows with Voltman in perfect synchronicity. Mars demands that Voltman tag his partner into the match.  They engage in further attacks, until Mantaro warns them to watch out for the partner, but Voltman seemingly gains the upper-hand, until Mars performs the Swallow-Tail. At that point Asuraman appears.  Asuraman traps Mars in an ankle-lock, after they exchange attacks, and Mars is then slammed into the mat, before he taunts Asuraman.  Mars attempts a double-impact, but is attacked by Voltman's Tesla Coil.  After Kevin enters the ring, Mars convinces him to tag out so that they can save Meat. 
Mars lands a 619 to Asuraman's abdomen, before Asuraman tags out with Voltman, and Mars teases that he must win in order to have a chance to fight Kevin in future. Voltman uses a Hell Light Bulb to blind Mars, so that his Swallow Tail misses. Voltman gains the upper-hand, until Mars is thrown into the ribs of the ring above.  Mars stops Voltman from attacking the injured Kevin; he uncovers that Voltman is weak to attacks he has not researched, and enters a combination attack with Kevin to gain an advantage. 
Mars puts on his Mask of Madness. 
Mars wraps his body with the elastic covers of the ropes, which leaves him impervious to the electrical attacks of Voltman, as the rubber provides insulation.  He becomes trapped by Asuraman's Vajra Entanglement, and - in his inability to escape - removes his Swallow Tails, which peels off the skin from his back, only to follow with the Ultimate Mars Buster.  The cheers of the crowd - all for Mars - inspire him to fight.  He starts to black out from blood-loss, and Asuraman reverses the hold and gains the advantage.
Mars forbids Kevin Mask from moving, as Asuraman grabs Mars by his hair.  He wraps himself again in the rubber from the ring, while Voltman opens the door to his body and reveals a microwave, and Asuraman shoves him inside the microwave, where he proceeds to burn. Mars realises the rubber won't protect him from the radiation, so he uses broken pieces of his tail to throw at Kevin - this keeps Kevin at bay. He is burned alive and dies inside the microwave, leaving behind only his mask and the rubber. 
After Mantaro defeats Asuraman and Meat is revived, Scar is revived by the Reborn Diamond.
Scarface is one of the Time Warp 8 and travels back in time to the days of the Legends (right after the Dream Chojin Tag Arc conclusion) in order to save Robin Mask from being killed and, by extension, Kevin Mask from being erased from time. During the construction of the time ship he is made leader of Team 1, who are to retrieve the Tokyo Jumbo Sight for the body of the ship. On the day of departure, he packs his weight training equipment in case the 20th Century equipment doesn't live up to his standards. On the ship he is placed in charge of the antimatter engines and he shows great disapproval after they discover that Rinko had stowed away on the ship.
When the Ultimate Chojin Tag Tournament is announced and after hearing of the Completion Bulbs from Meat, Scarface teams up with Jade to form the Super Trinities (スーパートリニティーズ) (named after them excelling at three things: Technique, Strength, and Looks). While claiming to be fighting for Kevin, Scar now has the ulterior motive of wanting the Completion Bulbs in order to become more powerful.
The Super Trinites fought against the Hell Expansions (Neptuneman and Seiuchin). Scar shocks everyone by wearing his old overbody during the entrances and then arguing with Jade over who gets to fight first. After Jade has a personal dilemma in the ring, Scar is tagged in. Scar mercilessly assaults Seiuchin and is even able to manhandle Neptuneman. After he puts on the Madness Mask his assault becomes increasingly brutal, Jade begs him to back off and tag in. Scarface ignores him and tries the Ultimate Scar Buster on Seiuchin, but Scar's luck runs out when Seiuchin manages to break free and begin a ruthless assault of his own. Scar is saved by Jade's new technique, Brocken's Repatriation, after which Jade tells him that it's okay if he wants the Completion Bulbs because they are still friends. After awhile, Jade finds himself about to become a victim of the Optical Fiber Cross Bomber, but Scar jumps in the way and becomes the victim in his place. The skin on his face is peeled off and Scar is eliminated.
He is later sent to the Hospital along with Jade, having survived the Optical Fiber Cross Bomber and his face bandaged. Soon, he and Jade escape from the Hospital to see the fight between the Muscle Brothers Nouveau and The Machineguns. (More to come)
