Freedom Cobra is Master Shake's tattoo who forced him to eat people, especially Meatwad's dog, Carl and the Doctor's hands. He only appears in Freedom Cobra. Every time he fed he "grew", or as he calls it "added on". The first tattoo was Freedom Cobra with a sword and a Danger City: Population Me sign. Next he was riding a rocket, next Meatwad and Frylock were being fed into a grinder and poured into the mouth of him. His last add on was his body was all around Shake.
- Freedom Cobra is probably based on Audrey II from the Little Shop of Horrors musical since both characters have urban accents and both grow as they eat blood.
