Flash Thompson was a Marine who lost his legs in the war. He signed up for a Cobra program helping disabled veterans. What he didn't know is Cobra was using this program to get test subjects for their Bio-Viper program. Thompson became the subject they were looking for as a host but not for his will. He was able to take control of his symbiote and form it to his will. Making him a versatile fighting machine. During his escape he encountered the Joes and was recruited by them.
