History Edit

Transformers: Retribution Edit

When the Nemesis caught up with the Ark above Aquatron, The Aerialbots Silverbolt, Fireflight, Skydive, Slingshot and Air Raid participated in the initial counterattack. They combined into Superion and crashed through the bridge before making their way to the hangar area to wreck the engines. The Aerialbots disengaged and were driven off by Megatron before completing their mission, and were seriously injured in the conflict.

By the time Sideswipe was prepared to use the Ark to buzz the Quintesson city Hydratron to rescue Optimus Prime and the others, however, the Aerialbots were back on their feet. They provided cover as the Ark descended on Hydratron, and Superion proved to be a powerful ally against the Sharkticon hordes. The Autobots and Decepticons formed a shaky alliance against the Quintessons, and so the Ark was forced to tow a damaged Nemesis back to orbit. Superion provided the boost necessary to get the clamped ships airborne.
