Green Lantern is up there, the dude can do practically ANYTHING with that Power Ring, as long as there's no yellow around...
I also dig Wonder Woman, an Amazon made from clay and capable of doing anything and she CHOOSES to come help humans even though her society frowns upon men (and any interaction with men)...
Monel (Valor/LarGand) is also cool, I mean you have to be cool to repopulate thousands of planets and be stuck in stasis for a thousand years without going COMPLETELY crazy...
I love Lobo too.. what a bastich he is with that uber powerful arm (even though his other one is spindly as a stick! lol) and his disregard for the 'rules'
Oh and Hellblazer kicks ass big time, I really enjoy the language they use in his comics and his sardonic nature along with some great storylines
There are way too many though to have just one favourite really
