8. Goldface

Let's talk about supervillains who really shouldn't be supervillains.

Keith Kenyon was a professional criminal (love that distinction) who was trying to invent an invulnerability elixir. Unfortunately, he needed to steal a bunch of gold to do this. He wound up stealing several treasure chests from shipwrecks, which"¦is that actually stealing? Real question here; let me know if you know, because I just always assumed sunken treasure counted as salvage, not thievery.

Kenyon eventually accomplished his elixir, as well as a helmet that could turn anything he wanted into solid gold. At this point, you don't really need to keep stealing things. You could just, I dunno, USE YOUR GOLD-MAKING HELMET TO MAKE A BUNCH OF GOLD AND SELL IT. Just off the top of my head there. But then, Goldface doesn't seem like a brilliant man.

As evidenced by the fact he decided to call himself Goldface.
