The Griffin children's half-brother and Stewie's archenemy, Bertram first appeared in Emission Impossible (FG311) as an unborn sperm. Though he and Stewie resolved their differences after a microscopic encounter, their hatred was rekindled in Sibling Rivalry(FG424), after Peter replaced all the sperm at a sperm bank with his own. Battling for control of the playground, Stewie and Bertram (along with other children on both sides) fought it out in the air, on the ground as swordsmen, and Stewie even briefly transformed into a ninja. Bertram is a dishonorable opponent, as he used biological weapons against Stewie. Stewie won the war, however, and Bertram mysteriously disappeared into the night.
Bertram shares many qualities of Stewie, to include intelligence, strategy. Bertram also has a football head like Stewie.
However, Bertram would make a comeback to face Stewie in the Family Guy Video Game; he is the last boss that Stewie fights.
