Santa Claus (American Dad!)

"Season's bleedings!"

- Santa Claus' famous quote.

"Yeah well I'm Santa,and maybe now even a dumbass like you can figure out that I'm the bad guy!"

- Santa about to shoot Stan.

Santa Claus is the main antagonist of the animated series American Dad!.

For Whom the Sleigh Bell Tolls
When Stan tries to teach Steve how to use a gun, the latter accidentally shoots Santa (whom at first they thought was someone in a costume). Upon recovery, Santa vows revenge against the Smith family. He later sends an army of elves, reindeer and snowmen to kill them. They are ultimately forced to retreat at dawn, though Santa declares he will try to kill the Smiths every Christmas Eve, thus bringing them a family tradition.

Minstrel Krampus
After Steve is kidnapped by the demon Krampus, Stan and Roger visit Santa to help rescue him. Santa agrees so he can kill Krampus, and when he does so he promises Stan a permanent spot on the nice list. However, it is later revealed that he lied, as well as the fact that - while Krampus was only punishing children for love and discipline - Santa was spoiling them with presents. After shooting Krampus, he attempts to shoot Stan, but Jack Smith sacrifices himself instead. After Santa and his elves retreat, the blood of Krampus transforms Jack into the new Krampus.
