Spock is awesome.
He uses logic as a weapon, a tool to twist the mind, and he can use his weird mental powers to render entire armies baffled. He is a Vulcan from the planet Vulcan, and, like all members of his species, he has buried his emotions to use logic and knowledge as weapons instead.
He also has a catchphrase, 'Live Long and Prosper'.
He apparently also has influence over certain sea creatures.
