Contrast to an Anti-villain; which differs from an Anti-hero; There aren't many good examples.
#Alexmercer of #Prototype for instance
MAYBE Kane of #Commandandconquer.
People who are obstensibly villains; but their actions end up saving people anyways, be it the goal or not.
People keep posting villains who had a redemption arc/changed to be good at the end. Twist Heroes are characters who others misconceived as the bad guys but were actually trying to do good all along.
