Teletraan-X (Cyberverse)

Teletraan-X is essentially a sentient back-up hard drive for Teletraan-1. While it wants to be helpful, its programming forbids it from helping anyone who is not a crew member aboard the Ark, a fact that it continually reminds everybody of.

It's quite hilarious, really.

Under undivulged circumstances, Teletraan-X was separated from the Ark. After spending "millions of years" searching for the ship, the little drone was found by Slipstream's squad who used him as the bait in a trap for Bumblebee, the only one on Earth whom the drone would respond to. When the Seekers began their torture of Windblade and Bumblebee however, the drone's programming compelled it to defend the Autobots, using its forcefield to knock down the Decepticons. Joining the duo in their escape attempt, Bumblebee and Teletraan-X were forced to leave Windblade behind.

Ever chipper, Teletraan-X spent the next four and a half hours recounting human history before Bumblebee outright asked him where the Ark was. Information that Teletraan... didn't know. Noticing that Bumblebee carried a cortical psychic patch with him, the drone offered to help the scout make sense of his jumbled memories. Within the scout's brain, Teletraan-X drew his attention to his memories of Optimus Prime, showing that even the greatest of heroes could come from humble origins and weren't infallible. Inspired, Bumblebee set out to rescue Windblade with Teletraan in tow. By the time the two arrived back at the missile complex, Windblade had already freed herself (mostly) and the trio made good on their escape. As they fled, Windblade revealed her data mining had allowed her to learn of another Autobot on Earth, buried somewhere on the planet.
