Brian Griffin (seasons 1-7)

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.

He's a talking dog and the best friend of Peter, Lois and Stewie, as well as an adoptive member of the Griffin family while also acting as a voice of reason for them whenever they have problems. He's voiced by Seth MacFarlane (that also voices Peter, Stewie, Quagmire, Carter Pewterschmidt, Dr. Hartman and Tom Tucker).

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. He also has a great chemistry with Peter.
 * 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 are some 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 that make him relatable for the audience.
 * 8) He does gives some bad people the punishment they deserve, like in "Barely Legal", where he scolds Connie D’Amico and calls her out for her awful behavior towards Meg, which is satisfying.

The Only Bad Quality

 * 1) He was hit hard with mh:loathsomecharacters:flanderization in the new seasons.
 * 2) Even before Season 8, he still has his unlikable moments like when he tries to kiss Lois Griffin in Play It Again, Brian and when he neglects his own son, Dylan in The Former Life of Brian. Though a season 2 episode does show him having a crush on Lois, he didn’t stoop that low and he and Lois agree that they should only be friends.
