Little is known about Stryder’s past. Only that before becoming the ultimate reptilian terror of The F.I.S.T, he was once a freedom fighter from Brazil. He fought alongside a small militia that stood against the remaining F.I.S.T threats who made themselves present across South America. He was kidnapped during a botched mission, and mutated by F.I.S.T. scientists using different variations of reptilian DNA. As a result of his mutation, majority of Stryder’s memory had be lost, and replaced with the desire to destroy all that’s in his path.
