characters dark side

I would have to say Lucy and Nyu,that is order Lucy small eye and Nyu Big eyes, from Elfen Lied the Bloodiest and Goriest Аниме Ты will ever watch

Honi Senpai from ouran, he might look cute but when he's mad U BETTER WATCH OUT!

Father Able Nightroad - Trinity Blood
He has a serious dark side!

kyo(Skip beat) is very ify there

Hmm..I'm not sure if this is what Ты mean but this is Dark Marik from Yu-Gi-Oh!..he's Marik's dark side but they are kind of separate but he was created from Marik's Hate and Anger towards the Anonymous Pharaoh and making him wait so long and him being a tomb keeper..he even sent his father to "hell" also known as the shadow realm in the english dub.

Shion from higurashi

tobi's not always a good boy....he has a dark side tooo....

um...well there IS this guy from my Избранное Аниме who got possesed by Dark Power... i know. O_O Dark Power. never mention it. whatever. XD
anyways, he battled this guy, thought he had a strategy, totaly failed, then....oh man it was scary. HE GOT POSSESED!
anyways, he broke free of the dark power at one point, wich kinda ruined it.
i mean, watching him all evil makes Ты want to run and hide at first, but after watching it a million times, Ты get used to it, it isnt scary, and it just plain fun to watch. :D
NOT MENTIONING CARACTER или ANIME! ._." im a little embaresed cause some-ok, most- think its stupid...

Hatsuharu sohma

Light Yagami from Death Note..

I don't want to spoil the Аниме if Ты haven't watched it..so I'll leave it at that.. ^-^

Sasame from Pretear.
At the beginning: Ты did fine, Himeno. Keep working hard! *smiles and freaking rainbows*
Nearing the end: Ты will all die if Ты do not embrace the Princess of Destruction's will.
