I tried to power scale family guy. Here is my tier list.
I think Meg is ahead of Peter because she defeated Ernie seemingly for good, while stewie is still young so he can get stronger with age.
Cleveland is in potential tier because when he bulked up in the early seasons he nearly defeated quagmire but doesn’t train/ fight much to my knowledge. Patty is in potential tier because Brian said she was in good shape at least. Dunno about the rest of Meg’s friends.
I’ve included a tier for characters I’m not sure about.
