Growing up in a number of orphanages and foster homes in New Jersey, Sidney Green was a boorish, clumsy child, often the target of cruel bullying, by children and adults alike. Also an inveterate bed-wetter, Green carried around with him the funk of uncleanliness, which further ostracized him and made him miserable. Green's attempts to curb his nightly emissions by avoiding liquids led to dizziness and dehydration. Once his mutation manifested, a blissful drought beneath the waist set in, and there was a lack of sodden sheets. When Green joined Xavier's he was put in Gambit's Squad. As a student at the Xavier Institute, Green had regained some confidence, forwarding audacious advances to aesthetically stirring female student Foxx. When Foxx was exposed as Mystique, Green sensed betrayal and attacked her. Within days, Green was able to walk again. Yet, the experience of being smashed in the head with a flush-lavatory triggered unfortunate memories of his childhood, perhaps permanently traumatizing him.

Sidney retained his powers post M-Day and is still residing at the school. Onyxx was critically injured by Reverend William Stryker during his attack on the institute and barely survived.

Onyxx was seen captured along side his fellow students in Limbo.

Following the events of Messiah Complex, Onyxx joined the X-Men in San Francisco and was seen training with Colossus and Rockslide in Manifest Destiny.

During the attack of Selene's Inner Circle in Utopia, Onyxx was killed by Wither.^[1]
