*laughs* Thanks for reminding me! This one's from a friend of mine from college days, telling me about an old game of his, where someone created a character named Warhead. Pretty simple power structure ...
Duplication (4 duplicates). The duplicates had:
A squidload of Superleap, and
A no-range killing explosion, both with one charge each.
Basically, he'd split off his duplicates, then they'd leap at someone, land, and explode, dying messily. Of course, after a couple of games, they realized that dead duplicates STAYED dead ... so the explosions became personally immune, and the duplicates would spend their next phases running for their lives back to the original.
