Fictional character biography
[edit]As a child, Sidney Green lived in various foster homes and orphanages, unable to find acceptance because of his crude behavior and chronic bedwetting.[1] This was cured after his mutant abilities activated, transforming him into a four-eyed golem-like creature.
Subsequently, Sidney becomes a student at the Xavier Institute as Onyxx and joins Gambit's training squad, the Chevaliers.[2] He develops a crush on fellow student Foxx, who is later revealed to be a disguised Mystique.[3]
Sidney is one of 198 mutants who retain their powers after the Scarlet Witch depowers most mutants on M-Day.[4][5][6][7] He is later killed by Wither before being resurrected after the establishment of Krakoa.[8][9]
Powers and abilities
[edit]Onyxx has a craggy granite body, which gives him superhuman strength and durability. He also possesses an additional pair of eyes, but it is unknown if these serve any special purpose.
