Brimstone (Cybertron)
| The name or term "Brimstone" refers to more than one character or idea. For a list of other meanings, see Brimstone (disambiguation). |
- Brimstone is a Jungle Planet Decepticon from the Cybertron portion of the Unicron Trilogy continuity family.

Brimstone isn't much for thinking. He's more comfortable taking orders from his leader Scourge, but when left on his own, would rather simply follow Undermine's lead. He really enjoys his position as one of Scourge's right-claw mechs, since it gives him an unrivaled opportunity to beat people up without reprisal.
About the only thing Brimstone's brain is good for is playing Praxus Fold 'Em. He and Undermine typically play during quiet nights in the Jungle Temple, with chores as the high stakes.

Brimstone was a denizen of Jungle Planet, one of Scourge's acolytes who joined him during his quest to enforce peace on Jungle Planet by any means necessary. Honor In the present, he attended to Scourge's needs at the Jungle Temple. Although Brimstone missed Megatron's arrival, he was present to observe a sparring match between Megatron and Scourge, and was impressed by the Decepticon's control and power. Deep Later, Brimstone was going for a walk in the park with his friends when some loud-mouthed Humvee had to challenge Scourge's strength. Never a good idea. Race Brimstone and Undermine watched eagerly as Scourge pounded on Overhaul, and didn't notice Snarl sneak off to help the interloper. When Overhaul returned for a second match, Scourge initially said he couldn't be bothered to fight the Autobot. He changed his tune after Brimstone and Undermine were battered aside by Overhaul as proof of his worthiness in battle. Detour
When Optimus Prime arrived on Jungle Planet, Brimstone journeyed out to confront the Autobot leader with Scourge. Unwilling to negotiate with anyone who hadn't proved their strength in battle, Scourge demanded that the Autobots and Decepticons fight before he heard any more about the Cyber Planet Key quest. Brimstone and Undermine kept Snarl and Backstop out of the contest at first, but soon it broke into a free-for-all with the Jungle Planet residents each aiding the Autobot and Decepticon camps. Savage As Scourge's entourage met the Autobots again in a narrow canyon, Brimstone matched his vanadium wing blades against Backstop's horn. Sand
As Optimus Prime came to Scourge's temple to once again ask for the Cyber Planet Key, Brimstone watched guardedly from the sidelines. The Jungle Planet warriors openly mocked Optimus for his refusal to fight for what he wanted, and for battling with his own arm in Savage Claw Mode, as Leobreaker bristled for combat. Later on, Brimstone and Undermine tried to prevent Backstop from entering the temple until Scourge granted his old sensei an audience. It seemed Optimus Prime had changed his mind, and would now meet Scourge for battle at a time and place of his choosing. Honor Brimstone and Undermine aided Scourge as he began to train vigorously for the match. He had himself chained to the temple pillars while still fighting off attacks by his subordinates. Eventually, Brimstone and Undermine called it quits because even a handicapped Scourge was too much for them. Once Prime arrived at the temple, he introduced them to the ambassadors from other worlds threatened by the black hole: Override of Velocitron and Lori of Earth. Brimstone was curious about the pint-sized creature, and moved in for a closer look. Primal
After Optimus Prime defeated Scourge in battle, he claimed the Cyber Planet Key, but allowed Scourge to remain titular ruler of Jungle Planet. Scourge, Brimstone and Undermine remained uninvolved in the conflict that followed as the Decepticons attempted to steal back the Cyber Planet Key from the Autobots. Trust

He comes with a silver-border Jungle-type Cyber Planet Key; the Hasbro version has the Key Code "d0h3" stamped on the back.
- The Takara and Hasbro versions have a variety of small color differences, largely in the realm of different shades of the same colors.
- Sideways, Brimstone, Thunderblast ("Value Pack", 2005)
- Brimstone was also available in a Toys "R" Us exclusive "Value Pack" alongside Sideways and Thunderblast; all three normally-carded toys were put in a large cardboard "sleeve" that let the bubbles stick out. This set retailed for $29.99... and since Deluxes were $9.99... not much of a "value" there.
