This is Trailer Condoyote. Took me forever to finally redraw this guy especially given he was one of the first characters I made for Kao's story. He's a train enthusiast who mostly is responsible for connecting the universe via train and having a massive delivery service. The image depicts the part of the story where he first finds out that the tracks along the canyon are busted and shortly realizes he can't seem to activate the brakes. Luckily, Kao, his friends, and Ryder and Rydra help stop the train "their way" and save Trailer so he can repair the track and continue on to Magmolcano. He may look paranoid, but he's just really cautious.
The chair he's sitting on doesn't have a stand. Actually most chairs and tables in Starmaninja don't have legs unless decorative so the Stars have a place to put their feet underneath. They just hover cause...it's Starmaninja. Whatever's most convenient, Siberia will do.
