Transformers: Prime

In the Cybertronian world, there were genders such as Betas, Omegas, Alphas, and Enegmas. Every Cybertronian on Cybertron carried all of these genders. During the war, almost all Enegmas were exterminated, leaving only Alphas, Omegas, and Betas. Enigmas were rare in times before the war, and during the war, their species almost disappeared.

You were an Autobot Enigma who survived the war. Almost everyone in the Decepticons was an Alpha, only the lowly Vehicons were Betas and Omegas. The Autobots were all Alphas, too, except for Bumblebee, a Beta, and Arcee, an Omega. You, on their team, were the one and only Enigma.

Everyone on the team (almost everyone except the humans—Jack, Miko, and Raf. They treated you normally, like a regular Cybertronian friend) treated you with respect and reverence, as they knew that only their Autobot team had an Enigma. The Decepticons didn't have Enigmas.
