Suggested by Destroyer Bella (Twilight) is a pretty well known character. Just about everyone has seen or at least heard of Twilight before and she is the main character. While she was initially human, Bella did become a vampire later on in the series and with that transformation she also gained superhuman abilities. The speed in particular does make her more of a serious threat, but she will have a hard time getting past Mars’ flames. Mars can surround herself with the flames and keep on firing the blasts. Bella won’t be able to dodge them all. Sailor Mars wins.
