Roberto grew up in a rich family from Brazil and was a very skilled soccer player. After his powers manifested the hellfire club and the X-men fought over him which resulted in his girlfriend dieing in his arms after taking a bullet for him. After this he joined the New Mutants and became best friends with Cannonball. When his mother who was estranged from the family because of her job as an archeologist invited him and his friends on an archeological dig they accepted and they saved her life from a hellfire club assassin. His father meanwhile became the white rook of the club. He briefly left the team and joined the fallen angels but rejoined before the team became x-force.
Upon his father’s death he became a pawn of Gideon an immortal mutant who used him as a test subject. Unknown to either Dr. Jashua used his blood on Subject 19 which resulted in Reignfire, essentially his twin. When Reignfire escaped he became leader of the Mutant Liberation Front and used his power over sunspot to attack the team. Cable later severed the link and he began dating his best friend’s girlfriend Tabitha Smith/ Meltdown while they were still together. When they were caught the friendship strained. He was eventually confronted once more by Reignfire who revealed their shared origin before he was defeated.
Roberto was next blackmailed by Selene into being the Black King of her hellfire club in exchange for bringing his dead girlfriend back to life. He accepted and left X-force. He resurfaced as the head of the X-corp Los Angeles Branch. When x-corp shut down he was approached by Sebastian Shaw to join his rendition of the Hellfire club but after Sebastian was injured fighting Pierce he became Lord Imperial of the club hoping to use it as a force for good. He was injured by the young X-men when they were tricked into attacking him.
When two of his former New Mutant teammates go missing he’s recruited by Cannonball to join the reformed New Mutants. After the successful mission they stay together and aid Cyclops on Utopia.
