Premo Vulcan is a massive creature that is taller than most brawlers. Premo Vulcan's mighty punches shatter steel plated armor. His gigantic fists detach from its body and fire cannon-like balls.
Premo Vulcan appears makes his debut in Taste of Defeat when Gus Grav battled Spectra Phantom in flashback and lost to Viper Helios. It is soon seen in ball form when Gus talks to him. Later, it battles Dan Kuso and Drago and wins.
In Return of a Friend, Premo Vulcan challenges Neo Dragonoid again. He won the first round, and he lost to Drago in the second round. He and Hyper Dragonoid were fighting him until Shun attacks and defeats Vulcan with Ingram and Hylash.
In Reunion, after the final Dimension Controller is destroyed, Vulcan is released from ball form and Gus rides him out of Vestal Palace only to find Mega Brontes and Elico. Vulcan and Elico then helped an injured Helios onto Spectra's ship.
