Fireworm

Fireworms were a type of creature that existed in the galaxy. In 9 ABY, the human Hunter Sentinel did an interview for the sporting competitive show Hunters of the Outer Rim and told stories of his Imperial service as a stormtrooper. In his reminisce, Sentinel claimed to have beaten a Fireworm during his deployment on a lava planet—although he was unsure if it was Senna or Mustafar—by shoving a Permafrost crystal in the creature's maw. Another competitor of the show, Imara Vex, later came to the interview and debunked Sentinel's stories.
