Burpy is an Infurnus Slug. He was part of Will Shane's arsenal until he was sent to find Eli right before Will went missing. He is Eli's faithful companion, an ultimate fire-based weapon and master slug strategist. He's also the general to Eli's army of slug buddies. Extremely loyal to Eli and more clever than your average slug, Burpy's got slug moves most people have never even seen before like Fire Wall.
Burpy debuts in The World Beneath Our Feet Part 1, where he finds Eli Shane, after Will Shane is "killed" by Dr. Blakk. He directs Eli down to SlugTerra, where they meet Pronto, a Molenoid scavenging Will Shane's roost. They head to a tournament qualifier, where Eli outwits Shockwire, and defeats him with Burpy. Burpy is also shown to have a friendship with Joules.
In The World Beneath Our Feet Part 2, Burpy helps Eli to win the first round and get Banger. He is also one of Eli's many slugs to help him get into the final against John Bull. During the final match, Eli shoots Burpy as his last slug and Burpy takes on John's ghoul slug and loses thus making John the winner. Later, when Eli is dueling Dr. Blakk and his henchmen, Burpy unleashes his fire wall and defeats 3 ghoul slugs helping win the battle
In The Slug Out, Burpy defeats Billy's Hop Rock during the trickshot match and also wins the duel against Billy for Eli. When Billy returns with ghoul slugs, Burpy uses Pronto's device and unleashes the Grenukes on Billy and his gang therefore eliminating most of their slugs.
In the episode Lightwell he has contracted a sickness from exposure to Ghouls. The only cure is to reach The Lightwell. On the way there he had only gotten sicker. Finally, Eli is able to overcome many obstacles obstructing the way. There, Burpy recharged for a minute as Dr. Blakk attempted to destroy the Lightwell and Eli who was trapped. However as Blakk decides to destroy Eli first, the well manages to cure his ghouls, giving Burpy enough time to emerge. There he knocked Blakk into the wall allowing the Shadow Clan to take Blakk.
