Took me a bit of time and thinking to come up with the answer to this question...
My answer... Johan Liebert
from the anime Monster
I could explain his character... but I'd rather just tell you all the general plot of Monster
as I assume a lot of you have yet to watch the show.
Just a little bit into why I like his character... he is literally the best villain ever. Without any special powers he just needs to speak a few words he can make someone do almost anything... all they need is a little suggestion... >:)
Also heads up the show is quite dark so if that's not your cup of tea...
Kenzou Tenma, a renowned brain surgeon of Japanese descent works in Europe (Germany). He has everything a loving wife, praise from his fellow workers and is right about to have a HUGE promotion. Then he is given the choice to save either a small boy, or the town's mayor. The higher ups are aware that the only person who can possibly save the Mayor's life is Dr. Tenma, thus tries to send him over to the Mayor when the small boy was about to be operated on. The boy is in a similar condition as the Mayor, and as a result of Dr. Tenma's morals he saves the boys life and forfeiting the mayor's life. A doctor is taught to believe that all life is equal; however, when a series of murders occur in the surgeon's vicinity, all of the evidence pointing to the boy he saved, Johan Liebert
. After he finds this out he goes on a journey all across Germany to find and kill the boy which he saved.
Seriously though this is an amazing watch, although it's a bit long going on for 74 episodes.
