Evac

When Evac received the transmission from Optimus Prime, inviting the surviving Autobots to Earth, he knew he was needed there immediately. The final battle against Megatron could only have resulted in massive damage to the world, which meant that his skills would be critical. As a rescue specialist, Evac has spent his life traveling from one disaster zone to the next, protecting and saving those he could. He is totally fearless, willing to risk anything to help his fellow sentient creatures.

History
Evac was a veteran that often helps Grapple and Hoist rebuild many damaged cities and often transforms into his Helicopter mode to attack enemies from above. He flies pretty fast and was often ordered to evacuate civilians out of the war.
