Autobots

The Autobots (オートボット, Ōtobotto) are a group of Cybertronian freedom fighters that are against the tyranny of the Decepticons, who were lead by Megatron and the societal oppression of the Caste system.

"We are autonomous robotic organisms from the planet Cybertron." "But we are mostly called Autobots for short."
 * —Optimus Prime and Ratchet.

Dynasty of Primes

 * The Nine original Primes
 * Vector Prime (Richard Newman): The master of time & space. Though recorded history pegs him as 25 million years old, he has identified himself as 9 billion years old, making the clockwork-covered Transformer one of the Thirteen. He's so old that in many timelines, the locals have called him "the First Autobot". Despite his age, Vector Prime is very powerful, and can warp both space and time, though excessive use of this power can severely weaken him. His powers allow him to traverse the multiverse at will, allowing Vector Prime to track and record events across a countless number of realities. Indeed, he was once a multiversal singularity, existing as one being across all of time and space, but that is no longer the case. He transforms into a White Cybertronian Jet similar to his Cybertron counterpart.
