Arcee

Arcee is the swift-cunning of female Autobot and membered Society's most fastest and bravest when protecting her Society friends.

Canon Bio
A former scout on Cybertron before the Great Exodus, Arcee is the least physically-imposing of Optimus Prime's crew, but she's also Optimus's most reliable soldier, his go-to gal when he needs someone he can count on. Whatever she lacks in physical form she more than makes up for it in force of personality. She is tough as nails at all times, always ready with a snarky quip even in the face of deactivation, not afraid to bend the rules every now and then, and seemingly never, ever scared.

Before the war, Arcee had been spying in Kaon, and sometime during it she had been rescued by Cliffjumper. When Optimus ordered the Autobots to Earth, her ship had been destroyed, and she was willing to wait as she detected the Decepticons had returned to Cybertron and they were planning something big. There, she entered a base and annihilated the Vehicons there, inadvertently returning Cliffjumper's favor. She hacked into the Decepticons's communications signal there, and found their weapons lab in Kaon. Arcee found Cliffjumper a brash soldier inappropriate for her stealthy mission, but he convinced her Kaon was too dangerous and that she could use his ship to go to Earth.

The duo entered the city through the maintenance tunnels Arcee had once explored, and she found a secret staircase by activating an Autobot symbol on the wall. There they discovered Starscream had rebuilt a space bridge to travel to Earth. Concerned by the repercussions of the Decepticons's discovery of how to build space bridges, Arcee wanted to destroy it, but Cliffjumper convinced her it was their way off Cybertron. Distracting Starscream with a ruse, Arcee activated the space bridge and overloaded its systems, jumping through it with him before it blew up.

Landing on Earth, the duo scanned their alternate modes and traveled to find a population center where they could build a scanner and find Optimus. Starscream attacked, having also jumped through the space bridge, blasting Arcee's arm off. Cliffjumper fought him and tried to get Arcee to safety, but she refused, telling him to leave her and find Optimus. Optimus and Bumblebee appeared, fending off Starscream and Breakdown. Optimus carried Arcee through a ground bridge to base, where Ratchet reattached her arm.
