Coppertop is a well-conceived pure thug of a supervillain. It's quite refreshing to find a real thug rather than the never-ending hordes of supervillains that want to take over the world or indulge in some other gradiose scheme... and of course, they need minions and enforcers so perhaps that's where you can use him.
There's a whole backstory to the fellow, but basically Coppertop was a fairly ordinary and quite grumpy electrician who encountered a wierd rock in a thunderstorm and emerged from the experience with certain powers, notably the manipulation of electricity and super-strength. Don't get him wet, though. He is well detailed and the backstory makes sense in explaining how he is now.
A simple adventure idea using him is included, although it makes little use of his abilities. Yes, he's a thug and he's being one in the scenario outline, but there's no reason to use him rather than anyone else. An inventive GM shouldn't take long to come up with a better use for him - perhaps some other supervillains are planning a heist or some other escapade that needs a black-out, and Coppertop shorts out a sub-station or even part of the grid for them. Maybe it's a plan to thwart democracy by crashing out the voting machines on election night...
Anyway, a nice low-level villain to tuck away for when the need arises.
