Burner is a Lavalynx Slug who belongs to Eli Shane. He is first used against Billy in a trick-shot contest and wins. Burner appears again in "Shadows and Light", where he is used for defense against the Shadow Clan. While rarely seen in the show itself, Burner makes several appearances in Slugisodes.
