Post an জীবন্ত character আপনি DON'T want to mess with!

Yuno Gasai from The Future Diary. If I had anything close to a crush on Yukki, I'm pretty sure that there would be আরো blood outside of my body than inside.

Killua Zoldyck,when he is on his assassin mode

Accelerator from To aru Majutsu no index.....

~The most dangerous জীবন্ত character I've ever seen, I don't want something like him as an enemy ⌐.⌐

Death the Kid from Soul Eater

I don't wanna ruin his symmetrical image.

Taiga Aisaka (A.K.A.: Palm শীর্ষ Tiger) from "Toradora!" She may be small and Kawaii, but আপনি make the wrong সরানো and she'll go "cat scratch" on you!

I don't think আপনি would want to mess with Sebastian Michaelis.

Professor stein

I DON'T WANT TO BE DISSECTED!!! *runs away screaming hysterically*

France! He scares me *Shivers and sits in a corner*

Kisuke Urahara (Bleach)

when he is serious state.....he heeh

erza scarlet from fairy tail

any and all of the titan shifters

Everyone in Hellsing Ultimate, they'll destroy you, especially Alucard (`` OnO)

Kenpachi Zaraki (bleach)

Three of the Four Heavenly Kings:
Left-Coco
Center-Toriko
Right-Sunny

Hotaru Rindō from Qualidea Code

Push Mephisto far enough and piss him off and you'll probably regret it...
He's so scary when angry. ;-;
He won't exactly hurt you...but you'll end up questioning your existence pretty hard...you'd probably need therapy...
(Amaimon is also someone আপনি don't want to piss off. He's violent and holds a grudge...)

Gemini Saga from Saint Seiya.Virgo Shaka from the same জীবন্ত is another character that I wouldn't want mess up with either.

I'd have to say Pharoah Atem/Yami Yugi From Yu-Gi-Oh! since although he obviously knows about Shadow Games and Penalty Games and also has the ability to CONTROL them, as well as monsters, magicians, and other powerful cards. Push him far enough to where he's going to want to literally DESTROY আপনি and আপনি are done.
