Spock

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 helps the Federation in their wars, and used to serve on the USS Enterprise. He was the science officer, which makes Data his spiritual successor.

He apparently also has influence over certain sea creatures.
