Venom

Venom used to be an ordinary Weirdo criminal, but a poisonous space alien called the Gollionk mutated him by forcing radioctive earthworms down his throat, and he became a super villian. Venoms real name is Edward Zeal Yinfield but because of his horrible appearance and green colouring, people call him Venom. 
Venoms arch enemy is Robbert Vern aka "Anti-Venom". They lothe each other and will fight to the bitter end if the see each other.
