A crossover-ish story where Soundwave, Rumble, Frenzy, and his minicons went to another world after the 'cons lost the war. He wasn't able to adapt to the sudden change so he found a way to live in a different place to not be seen as evil anymore. Meeting a familiar face while he, and his minicons, work for them and live in Ponyvile for a while.

Although, Soundwave will have to get used to a certain chaotic creature being around him and his minicons.

This came from the whole IDW Transformers/My Little Pony crossover comics.
