Brimstone is one of the main antagonists of the first season of Slugterra. He is the ruthless ruler of the Darkbane and is determined to lead his army to victory in conquering all of Slugterra and returning the Darkbane to their former glory.


Brimstone debuted in the episode What Lies Beneath, where he was seen on his throne in the Deep Caverns and introduced himself as the High Commander of the Darkbane. He would then go on to saying that they (Shane Gang) aren't the first midlanders to enter the Deep Caverns, and that he has dealt with Humans before, including The Shanes. In What Lies Beneath, Brimstone intended to break through the Guardian Gate force field and lead his army into SlugTerra, however they would fail but he promised that him and the Shane (Eli) would meet again.

Brimstone's later seen in a flashback in Back to Blakk, where Blakk is seen making a deal with him and the Darkbane, where they would supply Blakk with Dark Water and in exchange Blakk would have to allow one of the Darkbane to disguise themselves and return to Slugterra with him.

Brimstone then reappears in Light as Day, where he and the Darkbane finally enter SlugTerra through their and Blakk's terraportal drills, but are stopped by the Shane Gang and the Shadow Clan.
