Cyborg (DC Comics)
Victor Stone is fortunate to be a jock and a geek at the same time. After a freak lab accident, Stone took advantage of his science knowledge and became Cyborg. His brilliance is the reason the Teen Titans had weapons, vehicles and a technological headquarters.
Wally West aka The Flash (DC Comics)
Wally West recreated the experiment that gave the original Flash (Barry Allen) his powers. His love for science is the reason he is one of the most popular characters in the DC Universe. In the Young Justice animated series, we got to see how much of a nerd he was.
