|First appearance||"A Taste of Freedom" (4ACV05)|
|Voiced by||Maurice LaMarche|
The Pain Monster is a monster hired by Richard Nixon to spend a weekend with any Earthican that chooses not to pay their taxes. Considering his name, it can be assumed this weekend wouldn't be very pleasant for the non tax-payers.
Richard Nixon: My fellow Earthicans, we enjoy so much freedom, it's almost sickening. We're free to choose which hand our sex-monitoring chip is implanted in. And if we don't want to pay our taxes, why, we're free to spend a weekend with the Pain Monster!
Pain Monster: See you April 15 folks!
- Despite a fearsome name and appearance, it has a pleasant and cheerful voice.
