27 best fighters in the Arrowverse, ranked

19. Brainiac-5

Brainiac-5, or Brainy to his friends, is a member of the Legion of Superheroes from 1,000 years in the future. He first arrived in the present time with Mon-El and Saturn Girl during Supergirl season 3 and spent most of his time acting as the Legion’s man in the chair. His intellect allowed him to plan for anything and solve complex equations in seconds, which made him an extremely useful man to have around.

Once he returned to 2018 and took the place of Winn Schott at the DEO, we began to see a lot more of Brainy. This included his remarkably unique fighting style. As he’s basically a walking supercomputer, Brainy uses deductive reasoning to predict his attacker’s movements and avoid them. This produces what appears to be a well-choreographed dance.

Brainy truly shows that brains can be as valuable in a fight as brute strength. His fighting style is something that hasn’t really been seen on television before and he certainly deserves a place on this list for the sheer imagination behind it. He’s no slouch either, particularly when you consider that he took out the Amazo android single-handedly during the Elseworlds crossover, something which took the combined might of Barry Allen’s Green Arrow, Oliver Queen’s Flash, Supergirl, and Superman.
