Ok, I know, there’s lots of those, but I have clues! Just nothing I can use Google on, so instead I come here. I know you guys will help.
Here’s what I remember: typical superhero team setup. I know most of them got their powers in the same manner–I can’t remember how. I know one of them was dead, he looked rather like the cryptkeeper. And one was a kid, but only his father and one of the other teammembers knew about it. He got his powers differently–he was in an experiment or something that gave him the ability to change himself physically for a certain period of time, after which the shell would become a pile of green goop and he’d climb out of it back to normal. He was a big muscle man named Prime (only name I remember).
Ring any bells?
