who is the most scary Anime character?

Mine from Karneval?

I would say Lucy from Elfen Lied because she can be mew oder turn into a Murderous girl that can kill people with invisible hands (sorry no pic too lazy but the Anime Hintergrund has her at the very right side)

hmm...
Rena and Shion from higurashi
yuno and that 5 yr old from mirai nikki
captin of squad 12 in bleach
maria from umineko no naku koro ni

Belarus from Hetalia. O.O

The stalker from Perfect Blue... o____o;;

Kenpachi Zaraki (Bleach)
