Baribarian

The Baribarian is a giant spherical space fortress/city utilized by the Universal Reckless Driving Tribe Bowzock in Gekisou Sentai Carranger. The outside of the fortress is covered in ring-like roads that constantly have vehicles moving on it, while the interior is one-part spacecraft and one-part home for the Bowzock. Its most notable landmark is a bar where President Gynamo and the main Bowzock forces hang out and plot to blow up Earth or defeat the Carranger in.

Ultimately after defeating the Carranger on his own by absorbing the Kurumagic constellations into his own body, Reckless Dash Emperor Exhaus (the shadow master controlling the Bowzock making them destroy planets) throws the Baribarian fortress towards Earth with the space gang in it, treating them as the "trash of the universe" and using the fortress as a means to eliminate Earth and the Bowzock simultaneously. The Baribarian is saved by Signalman, who uses the Sirender mech to catch the fortress preventing the collision. Ultimately once making peace with the Bowzock gang, the Carranger take the fortress themselves and use it to slam right into Exhaus, destroying it and likewise freeing the constellations to regain their powers.
