When the Asgard became stuck in orbit, the Rescue Bots launched their ship again, with Boulder navigating, and Chase and Blades as co-pilots. They also had an unintended stowaway in the form of Cody Burns. The Sigma reached the stranded ship, but Heatwave found that the tether cable was jammed, so he had to jump to the Asgard without it. Once he'd rescued Graham and Doc Greene, they used the Sigma to tow the Asgard back to Earth. Space Bots
Notes
- Art released by storybook artists Bull-Pen Studio showed the ship to have a design extremely similar to Transformers Animated Omega Supreme, and labeled images of the interior as "Teletran 1 bridge". The ship remained unnamed in any published fiction until "Space Bots".
