She may have the most useless ability (I can stop time! But if I do it'll kill me! Wait...what?

), and big obnoxious headgear, but Elita-One gets my vote for whupping Shockwave's ass.
And does anyone else think that "Elita-One" sounds vaguely similar to "Leader-1?" Perhaps the writers of Transformers were sticking it to their rivals at Go-Bots by making their most heroic character into Optimus's girlfriend.
