A group of all female transformers, the Amacons have separated from their male counterparts to escape from the bigotry they suffer.
When female transformers were first invented, they faced bigotry from their 'male' counterparts who felt they were not suited for anything other that creating new bots. While many females have fought to prove that they are just as capable as the other bot types, many have simply decided to leave Transformer Society behind and have founded their own home, on a planet in the outskirts of known space.
Their sudden loss has some Maxigons calling for all remaining females to put to work creating new bots, which many of the newer bots and the remaining females have fought long and hard against.
Despite their dislike of male bots in general, they are also not fans of the Darkcons who treat female bots even worse.
