Junkion

Junkions are a race of transforming mechanoids that inhabit the garbage planetoid Junkion (also called the Planet of Junk).

Anatomy
Junkions have a unique physiology that share similarities with Cybertronians, as they are occasionally descended from them. They seemingly made of little more than the same rusted scraps of trash metal that compose their homeworld.

Powers and abilities
Junkions are capable of withstanding damage that would normally incapacitate or kill the average Cybertronian.

Junkions can repair their damage using any pieces of scrap metal they can get their hands on. For example, a Junkion that has been reduced to a pile of parts can come back at their enemy less than a minute later.

Junkions in battle are utterly fearless, using tag-team and ambush tactics to keep mobile while swarming their opponents en masse.

Junkions are expert mechanics, being able to repair Cybertronians that normal medical science would write off as dead with remarkable ease. However, how they have developed in this manner has yet to be explained.

Culture and society
Junkion culture is centered on Earth broadcasting, as evidenced by their speech patterns. As such, they are instinctively protective of Humans, the source of television.

Junkions are somewhat childlike, naive, and curious. However, they also tend to be wary of, if not outright hostile towards, newcomers to their planet. This is because far too many have come with the goal of harming their world. Luckily for off-worlders, once a Junkion's friendship is gained, they go "coo-coo for Cocoa Puffs" and treat their allies as Friends For Life.

After having come in contact with the Autobots, the Junkions have become known as some of the best scrap metal merchants and traders around. Even some Decepticons make use of their services. The Junkions are all too happy to exchange energon for more scrap metal... even if they do not think to ask just where the scrap metal came from.

Language
A Junkion's speech is a hodgepodge of television and radio clippings, making them oftentimes hard to understand.
