Sunshine worked alongside Chojin like Asuraman, as he worked alongside major antagonists in the series, and was eventually absobed by Akuma Shogun. He later planned to steal the Friendship Power of the Seigi Chojin, but was defeated in the Tag Tournament. After this, he retired from wrestling and was not seen again until Kinnikuman Nisei, in which he trains Check Mate and Rex King, and eventually comes to respect the Seigi Chojin on his defeat. It is at this point he explodes the dMp base and eradicates all evil Chojin, except for one that miraculously survives named Scarface. He is very rarely seen again within the anime or manga.
Sunshine appeared as one of the Devil Knights, a group of Akuma Choujin who had supposedly stolen the Golden Mask, a sacred relic on planet Kinniku that was once the head of a god. He fought Geronimo during the Five Story Ring battle within Warsman's unconscious body. Though he nearly killed Geronimo, he was ultimately defeated by his Apache War Cry technique after his weakness was discovered to be loud noises. Like the other Devil Knights, he was absorbed by Akuma Shogun before the fight with Kinnikuman.
Later, he and Asuraman escape and plot to steal the Friendship Power of the Seigi Choujins using Cursed Dolls. They enact their plan during the Dream Tag Tournament, where they compete as the Stray Devil Choujin Combo. After they are defeated by Kinnikuman and Kinnikuman Great during the semi-finals they decide that "Demons also have friendship", but Sunshine is killed by Neptuneman.
Sunshine appears first on a television set, after the Tokyo matches against the dMp members: Kevin Mask, Maxman and Tel-Tel Boy. He is with two mysteriously cloaked men, who are his two proteges, and he is also in Osaka after having defeated Gorgeousman and Barbarian.  He is a founding member of the DMp and head of their Akuma Chojin division. In the past thirty years, he states he has grown bitter and angry at the Muscle League, and has found two of the strongest proteges to get revenge on his behalf.  He declares his proteges are The Nightmares.They meet again in an izakaya (bar), where Sunshine claims that he is neither friend nor foe until the matches, and treats Mantaro Kinniku and Alexandria Meat in a civil manner.  He reveals he is now blind in one eye and lost much of his power, as well as feels abandoned by those of his team who sided with the Seigi Chojin, and - due to feeling alone - he doubled down on his quest for revenge. He notices that Terry the Kid has broken in the Osaka Dome via a portable television set, and orders his Nightmares to capture him. He leaves and reappears later to catch Mantaro in an adult establishment, despite him being underage, and so he blackmails Mantaro into being the referee for the following match.  Sunshine obtains a yellow card when Mantaro begins to help the Kid, as he steps into the ring, but he obeys and returns to observing the match from the side.  Sunshine antagonises the Kid to gain the upper hand, but soon Rex King is defeated and he infuses Check Mate with his spirit to make him stronger, so as to prepare for the second match against Mantaro Kinniku.  Sunshine announces the following match. 
It is revealed in flashbacks that Sunshine beat and tortured Checkmate, so that he would be impervious to pain and an invulnerable warrior.  Checkmate then reveals he carries a photograph of his old team, which he holds dear, and that he founded the dMp with two other members in hopes of gaining his own faction to control. Sunshine then intervenes with the match when Mantaro is unable to fight, begging Check Mate to stop, but - disgusted by his tears and emotion - Checkmate attacks him and pins him to the ropes.  He is devastated when Checkmate tears up his photo, which is his sole memento of the past, and follows this by preventing Check Mate from attacking a small child, saving the child's life. Checkmate proceeds to attack him, until he loses his eye-patch, and is eventually helped up by Mantaro. 
After Checkmates crosses boundaries in battle, he starts to cheer for Mantaro. This inspires the crowd to rally behind Mantaro and provide him invaluable strength and inspiration to continue.  Checkmate is then defeated. Sunshine refuses to allow anyone else to tend to his wounds, as he runs to his protege who he still holds with great regards and affection, but his colleagues in the dMp send an arrow crashing through the roof of the stadium to kill Sunshine.  His army back at base stages a rebellion, but loses in the fight, and so one creates an explosion that destroys all of the dMp and its base. Sunshine - in his bittersweet victory - carries a bleeding Checkmate out of the stadium with the promise to train him to be better.

Ultimate Muscle: Anime Changes
In the dub, it is explained that after the events of the Dream Choujin Tag Arc, when his friend Asuraman left to join the Muscle League, he grew a great urge to destroy Kinnikuman and the Muscle League, and that after the Devil Chojin were presumed destroyed, he had moved to Miami, Florida, where his appearance was ruined by sunburn (he claimed to have been banned from every public beach in South Florida, and that the lines on his arms no longer formed a perfect grid as he used to).
In the final season of the anime, he is seen with Clioneman and Dead Signal, indicating that he may have been training them.

(The Japanese name, "Suna Jigoku no Bannin", is a pun of sorts. "suna" means sand, whereas "jigoku" means "hell", hence "Guardian of the Sand Hell". However, an alternate reading/interpretation would be "Sunaji Goku no Bannin", which would mean "Guardsman of the Sand Prison", since "sunaji" means "sandy place/soil" and "goku" means "prison".)
