Brian Griffin is one of the two tritagonists (alongside Stewie Griffin) of Family Guy, one of the two tritagonists (alongside Peter Griffin) of Family Guy Presents Stewie Griffin: The Untold Story, and a minor character in The Cleveland Show.

Why He Rocked

 * 1) He's the conscience of the family alongside Lois Griffin (in the earlier seasons).
 * 2) He has a great friendship with Stewie which is one of the best parts of the series and is a fan favorite trait.
 * 3) Seth MacFarlane makes him different than the other characters by voicing him with his real voice.
 * 4) His sarcasm, snarky attitude and dry sense of humor is one of his most hilarious traits.
 * 5) His background is sad and heartbreaking.
 * 6) He's probably the smartest character of the series alongside Stewie.
 * 7) Despite being intelligent and mature, he still has flaws which makes him relatable for the audience.
 * 8) Even when he is flanderized in the later seasons, he became more likable along Peter Griffin and Quagmire.

Bad Qualities

 * 1) He was hit hard with mh:loathsomecharacters:Flanderization in the new seasons.
 * 2) Despite being still funny in the seasons after the earlier seasons he became an arrogant asshole.
