This one as another female demon, that I must say I am not sure if she is super strong or just uber fast. She slams a guys head into a wall with such force that his head goes through the wall. This isn't a very long web comic but I like it.

Has to female androids and while I have only seen one of them fight she is most assuredly a tough one. She likes to use guns to fight but she also uses her hands. In one panel she tears a guys head in two. Kind of messy.
