Thaddeus Griffin

Background and appearances
Thaddeus Griffin is a character on the cartoon show, Family Guy. He is Peter Griffin's evil twin brother. His first appearance in Family Guy is when Peter's mother Thelma Griffin leaves her husband (Peter's stepfather) Francis Griffin in the episode 'Mother Tucker'. Thaddeus suddenly appears from the Griffin's kitchen and declares that this event will affect his inheritance[http://en. .org/wiki/Mother_Tucker#Plot].

Later, in the same episode, (Mother Tucker), when his (and Peter's) mother, Thelma Griffin is dating Tom Tucker, and the two separate, with Peter believing that the separation is his fault and is on his bed crying, Thaddeus appears outside the window in a hot air balloon, points at Peter, laughs, and then strokes his moustache whilst saying 'Nhhiaaaa' in a comicly evil voice.
