Jean-Luc Picard

Jean-Luc Picard is Captain of a ship called the Enterprise, which hails from the Trek Galaxy. The humans there have an organisation set up there to defend them, known as the Galactic Federation. Picard rose up the ranks of the Federation because of his awesomeness, and ended up captaining one of their best ships.

He went on many adventures and fought many alien races, like the Romluans, Klingons and Ferengi. However, and possibly more importantly, he also secured peace between the Federation and a lot of alien races. He was the Captain who secured the cross-galactic alliance between the League and the Federation.

He was also assimilated by a Cyberman-esque race exclusivce to the Trek Galaxy, the Borg. He is one of the only living things to be assimilated by the Borg and then be re-habiliated and cured. He is also best buddies with his Commander, Data.
