Powers & Abilities[]

Superhuman Regeneration: Gilbert's body possesses an extremely fast rate of regeneration which is only active when he's been inflicted with grave injuries or blows which cause instant death. This ability is shown after Gilbert's head was cleaved in two by an Alterworld creature, who'd stolen Phillip's brain, but managed to hold onto consciousness and kill it shortly afterwards. However, despite being able to heal from pretty much any wound, this power doesn't nullify the pain which comes from his injuries.
