Fall of Cybertron
The Combaticons took part in the Decepticon assault on the Ark, but managed to avoid Metroplex. Onslaught and Brawl hauled Optimus Prime back to headquarters when he was captured by Starscream, and chained him up. As Megatron prepared to execute him, the Combaticons watched Metroplex kill him. The team retreated under Starscream's command at Optimus' recommendation.

When the Autobots made off with Shockwave's Energon, the Combaticons were assigned to sabotage and reclaim it, despire being annoyed at Starscream's leadership. Blast Off, Vortex and Brawl went off to bring down the bridge the transport was to roll across, while Swindle worked to shoot out the wheels. Despite their efforts, the transport suddenly became airborne. Swindle grappled his way aboard and was able to destroy the anti-aircraft guns, which had devastated the Decepticons' aerial assault, thanks to Starscream's impatience. Starscream ordered a retreat, but Onslaught ordered the group to combine into Bruticus as a last ditch effort to salvage the operation. Bruticus made it to the control room, but the transport was so damaged, it crashed and half of the Energon was lost. Starscream had the Combaticons jailed for disobeying his orders, even though Onslaught pointed out they saved a mission he screwed up from the get-go.

The Combaticon's were freed after Soundwave resurrected Megatron, who quickly deposed Starscream. Onslaught wanted to go after him, but Megatron let him go. The group accompanied Megatron to where Trypticon's remains were held, and combined into Bruticus to clear a path for their leader. The Combaticons were aboard the Nemesis when it left Cybertron, and took part in the attack on the Ark. The group combined into Bruticus and laid waste to the Autobot forces. However, Jazz and Jetfire managed to throw Bruticus off the ship and cast out into space.
