Forth is a dragon-like Decepticon Mini-Con. He is partnered to Quillfire and Back. He uses a form of magnetic repulsion as an attack ability. When paired with Back, who has the power of magnetic attraction, the two can be quite the formidable force.

Back and Forth were part of the group of Decepticons led by Scorponok and Glowstrike. Teamed with Quillfire, the pair accompanied their new boss into Crown City to scavenge auto supplies, and were in the process of doing so when Bumblebee and Strongarm found them in an alley. Forth used his powers to hurl several trash dumpsters at Strongarm, knocking her out of the fight temporarily, giving them the chance to escape as Quillfire towed a trailer full of pilfered parts. The Autobots gave chase, and the two Mini-Cons were dumped from the trailer when he spilled the contents in the hopes of evading his pursuers. They were able to catch back up to their boss after Quillfire knocked out the Autobots with a volley of stunning quill-missiles (having lost all the stuff he was trying to steal in the first place), and the trio made a break for it to try and salvage the mission.
The Decepticons hit an auto parts distributorship, but were interrupted mid-raid by Grimlock disguised as a crane. Back and Forth used their magnetic powers in concert to try and pull him apart, but were forced to flee when Bumblebee and Strongarm arrived. Moving to a nearby truck stop, the trio were again interrupted by the Autobots. Strongarm managed to lure Forth into trying to move a bus in an attempt to crush her, but the bus was simply too heavy, and the Mini-Con collapsed from the exertion. He, Back and Quillfire were all captured and taken back to the scrapyard.
Forth shares with Back the ability to manipulate magnetic waves and use them to move objects with ease. However, unlike Back's magnetic waves that drags in objects, Forth's magnetic waves pushes objects. This can be used as a counterattack against Forth as Strongarm is able to trick Forth into crushing her with a truck. However, due to the truck's large size and heavy weight, Forth collapsed from exhaustion.
- Forth's magnetic "breath" weapon is depicted with red energy rings, matching the color commonly used for the "north" end of magnets.
