Though most of the characters she's voiced are mostly likable. What unlikable characters did she voice?
Numbuh 363 from the KND episode I.N.T.E.R.V.I.E.W.S.
I can name Princess Morbucks from the Powerpuff Girls.
Numbuh 363 should be on the wiki, but not Morbucks because she is a decent villain.
Mindy from Totally Spies
