Cosmos



Cosmos is a young, but giftedly brilliant and respected astronomer[1] who knows quite a bit about space and alien planets. Unfortunately, he hasn't exactly gone out very much since he started his job. Little guy has zero social skills, which makes it pretty hard to get to the guy and know just what kind of person he is.

He turns into a mobile observatory buggy.

Fiction
Cosmos was visible among many Autobots celebrating the return of Sentinel "Magnus", and waved his alternate-mode nacelles (instead of his arms) in the air as Sentinel promised to hunt down Shockwave for assaulting Ultra Magnus. Later, he was seen cheering for Optimus Prime and his crew when they returned to Cybertron after their victory over Megatron.
