Quote - how about  something X for explosion in his name and the rest of his name from his planet or something.

Hmmm... he's from earth. The particle that gives him his powers is from 10,000 light years away from earth. We never know the name of the planet, as it gets vaporized when a star goes supernova...

But I am still working on it. I haven't given up all hope. I thought about giving him a name like Hancock. Not that specifically, but maybe something unhero-like...

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
