Sunfire (Shiro Yoshida) is a Marvel Comics superhero, associated with the X-Men. Created by writer Roy Thomas and artist Don Heck, he first appeared in X-Men #64 (January 1970).
Sunfire is a temperamental and arrogant Japanese mutant who can generate superheated plasma and fly. Not suited for teamwork, Sunfire was only briefly a member of the X-Men and has kept limited ties to the team since. He has had some presence in the greater Marvel Universe.
(Note: Sunfire first appeared during the era of the original X-Men when several explanations for the existence of mutant powers had been given, one of which was radiation. Genetic evolution is currently the most common explanation).
Shiro's mother died of radiation poisoning when he was young and Shiro grew to hate the United States, despite the influence of his US-friendly diplomat father. His greedy uncle Tomo inspired Shiro to take the identity of Sunfire and engage in a one-man battle against the U.S. He attacked the United States Capitol and battled the X-Men. Later, he saw Tomo kill his father. Distraught, Sunfire killed Tomo and surrendered to the authorities.
Sunfire has appeared sporadically in various Marvel comic books throughout the years. On a few occasions his temper has led to conflicts with other heroes such as Iron Man, Rogue and Wolverine.
In 1998, Marvel published a mini-series entitled Sunfire and Big Hero Six about Sunfire's brief membership in a new superhero team sanctioned by the Japanese government.
But now Deathstrike, who was more machine than woman, was able to restore her memories the same way one would a hard drive. Deathstrike kidnapped Blindspot, who released a photo of Sunfire, Rogue and Mystique to attract their attention to save her. Though Mystique never came, Rogue joined Sunfire, whose reputation had been ruined by the photograph, in Tokyo to discover why they were framed and who was responsible. The two ran into Lady Deathstrike, who in a heated battle cut off Sunfire's legs, leaving him in critical condition. Rogue surrendered to Deathstrike, who imprisoned the two. There, Rogue met Blindspot, who restored Rogue's memories and explained to her what was going on.
When Deathstrike discovered that the three were not actually responsible for stealing the adamantium, she went to kill them to destroy any evidence of what she had done. A weak Sunfire asked Rogue to absorb his powers so she could properly battle Deathstrike. Rogue had previously lost the powers of Carol Danvers that she had taken and was hesitant. She worried that she would harm Sunfire but Blindspot pushed her on Sunfire's face causing her to absorb all his powers and possibly killing him. With it, Rogue now also contained with her Sunfire's personality, similar to how she also once had Danvers' personality with her.
Sunfire's personality controlling her, Rogue went out to get revenge on Deathstrike, severely injuring the woman. The X-Men arrived in time to intervene, but Blindspot erased Rogue's memories of being an X-Man causing her to see her teammates as her enemies. After a brief altercation, Rogue's memories were restored and she told the X-Men what had happened to Sunfire. They went to where Rogue last saw Sunfire, but his body was missing leading some of the X-Men to believe he was somehow still alive.
Sunfire accepted, but after being chained away and locked in a prison while listening to the tortured screams of Gazer (another of the new Horsemen), Sunfire attacked Ozymandias and attempted to make his escape. Captured by Ozymandias and Apocalypse, Sunfire was transformed into the Horseman of Famine. When Apocalypse launched his attack on the X-Men, Sunfire caused an intense feeling of hunger and weakness in the mutants and humans on the institute grounds. As he was fighting the X-Men, Havok shot him down and Rogue, who recognized him, caught him as he fell. He was taken to the Medical Lab and Emma Frost entered his mind in an attempt to help him. When Apocalypse departed he sent War to retrieve Famine but Shiro broke free from Apocalypse's control and attacked War.
Sunfire was last seen running off with the unconscious body of Gambit, like him a former X-men turned Horseman. At the temple where Sunfire first took Gambit, Mr. Sinister told them, "I am glad you both feel able to move on from the past... for I am your future!".
Yashida and Yoshida seem to be different spellings of the same name. While in his first appearance, Sunfire was called Shiro Yoshida in the story arc that introduced his cousin, Mariko, his name was spelled Yashida and this version of the name was carried on in Mariko's next appearances. Although probably a typo, it could just be based on the Romanization/transliteration of the Japanese names. In addition, there is a phoneme in Japanese somewhat between an English R and an English L - at the time of his first story it was more popular to use an L, whereas nowadays one would write in Latin letters an R, which may explain the name Leyu instead of Reiyu. For example, Godzilla would today likely be spelled "Gojira".
After his transformation into Famine, a Horseman of Apocalypse, Sunfire gained the ability to use his flames to create flashes of light that affected the sections of the human brain which control hunger, causing any people who saw his light flashes to feel as if they were starving.
