Mini-Con city

The "Mini-Con city" is a floating and presumably space travel-capable city created by and for Mini-Cons, and possibly based on a design by Stella Holley. It is meant as a place where they can live in peace, far away from the bulks and their continuous conflicts. Humans are welcome though. The city is equipped with space bridge technology.

Shortly after awakening, the Super Stunt Team made it their goal to create a home where they could live in peace. They found no such place before destiny required them to team up with their peers to defeat Unicron. They were victorious and spent the rest of up to a year on finally getting themselves their own place.

During the Mini-Cons' absence from Earth, their human friend Stella Holley often thought of them and translated her thought into drawings. She was certain her friends would receive her feelings and one of the drawings she made was of a home for them: a floating castle.

When after a year the Mini-Cons returned to Earth, they channeled images of their new city to Stella: a floating fortress-like construction. Stella couldn't wait to meet them there.
