you're so vain

Ami likes word puzzles because they help train your brain. This time, she's thought of something that could help with locating enemies in disguise. Or maybe she just thinks it's fun... because really, how many of the villains actually have cars that they drive on a regular basis? Two? (sigh)

Villians are pretty vain, so they might have vanity plates on their cars! Whose car would have this plate?
Note: it may not always be a villain :p
