Toughest guy in anime

Encouraged thread from /a/.

Who is the toughest male character in all of the anime you've seen? A kinda guy that if you messed with you'd get your ass handed to you? and good god don't say anyone from Dragon Ball Z.

Possible people would be Batou from Ghost in the Shell, Brandon Heat from Gungrave, Chad Yasutora or Zaraki from Bleach. Theres a lot others too..

As much as Love Hina was a harem anime, the comedy in it was really wat made it shine.

Not to mention that the romance side of it was quite well written. Except at the very end.
