Old comic question

[DAMION99]

does any body remeber the name of the comic about a kid who develop an ability to change to this powerful as superhero
every time he would change he would like have to slime out
and his powers would run out and he would just start turning into and then he would turn to the kid. the kid was also able to decide which version of that superhero he wanted to be
it was a real good comic that had a show on tv

[Aaron King]

I think you're thinking of Prime.
