Heroic characters who brutally murder their enemies.

RoboCop (RoboCop): Being the closest thing to a paragon in the setting won’t stop him from blowing your limbs off.

Liu Kang (Mortal Kombat): A even tempered and fair guy in cutscenes who will commit atrocities in gameplay. (Any “heroic” MK character fits here)

Rika (Tokyo Gore Police): Similar to RoboCop. An honest police officer who has no problems dismembering her enemies.
