Gibbon

Martin Blank is a man who was seemingly born a mutant with an ape-like build and agility. Gibbon later joins a circus where he does well as an acrobat. His powers are later enhanced by a potion given to him by Kraven the Hunter to "Unleash the Beast Within". Martin Blank begins his career as a friend of Spider-Man's while wearing a gibbon suit. He even wants to be his partner, but Spider-Man laughs at him. Sick of being seen as a freak, Martin cannot take further ridicule and lashes out. He then catches the eye of Kraven the Hunter who enhances the Gibbon's powers with a herb broth, also giving him a great animal rage.
