G'Kar is the character of all time. He's a reluctant messiah. He's a Knight of the Round Table. He saved a stranger's life because "why not". He gave two of the top five speeches about freedom and equality in television history. When he was trapped in a life-threatening situation with his mortal enemy who wanted to work together to get out, he said "No. As the humans say, up yours. Die." He somehow got hold of multiple 500-gigaton nukes and no one ever questioned it because he's just like that. He's the galaxy's most prolific monsterfucker.
