Razorhorn is a bounty hunter working under Shadelock.
Season 2 1/2
In Mighty Big Trouble, Razorhorn worked as a bounty hunter alongside Shadelock and Roughedge. They were employed by Starscream to track down the Weaponizer Mini-Cons. The Insecticon and his team followed Starscream when he confronted the Scavengers, as he believed them to have the Mini-Cons he desired. Unfortunately, said Mini-Cons had already abandoned them before they arrived. The mission wasn't a total bust, however, as the Scavengers had managed to get their hands on the Dark Star Saber, which Starscream took for himself.
The bounty hunters tracked the Mini-Cons to a scrapyard, however the particular Mini-Cons Starscream was looking for had managed to evade them again, causing the bounty hunters to kidnap the wrong ones. However, the revelation from one of the Mini-Cons that Starscream's old enemy Bumblebee was on Earth as well was enough to change his tune.
In Mini-Con Madness, when Bumblebee escaped from the bridge, Starscream's crew prevented him from leaving the ship. They flanked Bumblebee on the bridge of the ship as Starscream related how he had escaped the Predacons on Cybertron. Razorhorn kicked Bumblebee when he insulted Starscream.
In Worthy, Razorhorn and the other bounty hunters guarded the Mini-Cons while Starscream searched for the seventh. When the other Autobots arrived, the battle spilled outside, where Razorhorn fought Strongarm. The combatants were all rendered unconscious by Starscream using the Dark Star Saber. When Shadelock and his men came around, they saw Starscream and Optimus Prime dueling, and opted to forget getting paid. Their escape was thwarted by the rest of Team Bee, and they were later secured aboard Optimus's ship for transport.
- Razorhorn was not named in his appearances on the show. His name was eventually revealed by showrunner Adam Beechen on his website.
