Eric the Siscon, calculative in strategy and violent in battle, his nature is protective towards his sister which in his case he has broken several bones of his enemies: thugs, bullies from highschool, perverts. He master many kinds of deadly technique such as:

-Whip of Mercury, the method of making the body as fluid as possible to enable it to act as a whip. This allows for the usage of the arms being as flexible as a whip that allows for the user to perform powerful "slaps" which affect the largest organ, the skin. Since the entire body is covered by skin, the Whip Strike has the same effect, no matter where on the body it hits. It doesn't matter how thick or tough the skin may be. The technique is so powerful, it can actually rip the victims skin off, and the pain is enough to cause most people to instantly cry out.

-Punch through body

-Mortal Kombat Fatalities and X-Rays
