I think "Animal Man" is a great name, especially considering who Buddy Baker is. It's very silver-agey, and seeing as how Buddy is not a dude who gets too crazy about the whole super-heroic thing, "Animal Man" is exactly the kind of name he'd pick.
Names that are so bad they're awesome: everyone in "Section Eight," from the immortal "Hitman."
Bueno Excellente
Sixpack
The Defenstrator
Friendly Fire
Flemgem
Shakes
Jean de Baton-Baton
and the best superhero name, ever, without a doubt: The Dogwelder.
