Cute characters that go evil

[Radical]

In any cartoon/anime, do you know any cute characters that are innocent, but are evil when they show their true colors:evil: .

Gatomon/Elecmon(Digimon)- Digimon Savers had an evil Elecmon in it.

I was thinking of the cat version of Yzma from The Emperor's New Groove, but she was evil to begin with.

[Darking]

The Giggle-pies from Fairly Oddparents

[Dr.Pepper]

Mushi from Codename: Kids Next Door.

[Anthonynotes]

Snooky Wookums, from "Krypto the Superdog".

[SantosLHalper]

The rabbit from Hoodwinked.

[DarthGonzo]

The Twonkies from the Jimmy Neutron episode "Attack of the Twonkies."

And there was a Duck Dodgers episode where Dodgers adopts a pet that turns out to be evil. "I'm also a licensed midwife" is one of THE best lines from that series.

[Wussycat]

That thing from the episode of 'The Chipmunks Go to the Movies' that parodied Gremlins.

[Skeeter]

ANYTHING taken in and/or adopted by Muriel in Courage the Cowardly Dog. The one that springs to my mind right off the bad, ironically, is the little duckling that imprinted Eustace as his "mama", and attempted to off Muriel at every opportunity.

Also, I would argue against Gatomon being truly evil. She was only manipulated and tortured by Myotismon, so much so that she repressed her memories of being a Chosen Child's Digimon. Even when she suspected Hikari of being the Eighth Child, Gatomon couldn't bring herself to kill her. After remembering that she was Hikari's Digimon and uniting with her, Gatomon dropped Myotismon like a bad habit, and later (as Angewomon) kicked his ass.

Let's not forget the Puuchuus from "Excel Saga". They don't just turn evil, they turn ugly too.
