Antonio is the bass player in Snakes N' Barrels. He is often seen with a top hat and sleeveless jacket with no shirt. Despite his success in the band, Thunderbottom suffered from uncontrollable alcoholism, which after Pickles' departure from the band forced him into poverty, obesity, and eventually sobriety.

Despite Thunderbottom's poor health and withered musical skills, Pickles managed to help restore his musical talent in time for a Snakes N' Barrels reunion concert, which unfortunately was sabotaged by the Tribunal manipulating the band into taking "Totally Awesome Sweet Alabama Liquid Snake" prior to their performance. Although the drug was intended to effectively wipe Pickles' mind and make him susceptible to the Tribunal's control, his years of drug use left him effectively immune to the drug, while Thunderbottom was mentally traumatized into a hallucinogenic state during the concert.

In their next appearance, the remaining members of Snakes N' Barrels had been reorganized once more by musician and sobriety spokesman Rikki Kixx, who had taken advantage of their brainwashed minds in order to further his agenda of forced sobriety. Thunderbottom, while still visibly obese, adopted a newer cleaner style of clothing to reflect his new message of Sobriety. Unknown to everybody but the Tribunal however, the Totally Awesome Sweet Alabama Liquid Snake was still present in Thunderbottom's body, and would cause madness-inducing phosphorus snakes to shoot out from every orifice of his body if exposed to bright lights, loud sounds ,and pyrotechnics. The unaware Kixx proceeded to hold a concert with Thunderbottom playing on bass, during which the drug became active once more in his system and caused the entire concert to fall into a state of inebriated madness. It is unknown what happened to Thunderbottom following the concert.



  • Like many characters in the show his surname is a joke. "Thunderbottom" is an insult thrown at someone who farts loudly.
  • Thunderbottom's top hat and long hair are an homage to Slash, the lead guitarist of Guns N' Roses.
    • Slash himself would later make a guest appearance in the episode "Tributeklok", voicing Thunderhorse bassist Billy Butterface. After being kicked out of Thunderhorse due to Dethklok's takeover of the band, Butterface and his bandmates form the Snakes N' Barrels tribute band Serpents N' Containers, in which Butterface dresses up as Thunderbottom.
