Roadrunner... Pretty much the fastest villain out there. Capable of running speeds of over Mach 5, he enjoys speed, money, and showing heroes (or coyotes as he likes to call them) who's boss.
Note: On this villain I didn't give him Megascale movement for a couple of reasons. First, a lot of GMs do not like it and would rather stay away from it. And second, Megascale movement makes it harder to get exactly where you want to go, usually only within a kilometer, but Noncombat multiplier makes it much easier to get to the exact hex he wishes to move to.
