Ratar-O and Vultureman used the Ratstar to capture Snarfer from the Planet of Snarfs with the objective of using him as bait for the ThunderCats on Third Earth. The ThunderCats came to Snarfer's rescue and crippled the Ratstar in the process, causing it to crash on Third Earth. Ratar-O ordered the Mutants to create the Mutank out of some of the parts of the Ratstar wreckage. The Mutank then towed the Ratstar back to Castle Plun-Darr. Lion-O searched the Ratstar wreckage for a hyper-space mega-condenser that Panthro needed in order to finish the Feliner. Jackalman salvaged the Vericannon and hid it in the forest. The weapon was later retrieved during Jackalman's Rebellion with the help of The Driller. By the time of the events of ThunderCats-Ho! The Movie, Part 2, the Ratstar was operational again and helped capture Snarf.
