Battlefurnace Groll was a Chitus warrior and member of The Six. He possessed special armor that allowed him to leap incredible distances due to hydraulic pressure and throw flames from his helmet with an aerosol fuel device. He met his demise at the claws of Uropygus, and was reanimated by her whip scorpions to fight against The Six and “The Party”. He was finally slain by Barbus and cremated by Wyrmslayer Eberstark. His armor was destroyed in the process.
