For example:
Mewtwo's uses the M from the middle of Samus (other M sounds sounded too harsh, because of the way it was modeled after the announcer's YouTube one where he emphasizes the "two," where "Mew" is softer.) So, it's M-you ("you" sound from "continue?") -TWO! (Two from, well, "two!")
They're far from ideal, but they're our best solution so far.
Thats cool
