Isla Ryker
During "The Gauntlet" storyline, the Rhino gives up his life of crime, surrendering himself to the police. S.H.I.E.L.D. removes his Rhino suit and sentences him to 25 years on Ryker's Island. He is released early on good behavior, and upon release, he meets Doctor Tramma, who wants to reinvent the Rhino. Sytsevich declines, and Tramma creates a new Rhino. At Spider-Man's persuasion, Sytsevich refuses to fight the new Rhino. That promise is broken when Sytsevich's wife Oksana is killed, and a grief-stricken Sytsevich kills the new Rhino.
