What ever happened 2 da gang leader wade in da first episode y doesnt he ever re-appear

Wade was never mentioned in the show after the Big Bang therefore his final fate is uncertain.

It's possible he died. It's never brought up in the cartoon(because it's a kids show) but in the comics it's mentioned that a lot of people at the Big Bang didn't survive(at least that's what I've been told. I haven't actually read the comics).
