The Ever-Burning Fire: Chompy first appears an egg on the planet of Magdomar founded by Rapheal. When he hatches Raph calls him cute and the little guy bit him giving the fire tortoise his name. Raphael had to find him his mom in which wasn't easy with the Triceratons in the way, soon Chompy lets loud a small cry in which awakens Tokka. The only way the turtles could get the fragment was climbing Tokka, so Raph left Chompy with April and Casey. But, what the duo discovered was that Chompy was Tokka's baby and April returned him. Even though, the gang tried their best the triceratons get the last fragment and to make matters worse the empire destroyed the dwarf star in the hopes of destroying Tokka. After that everyone was sad that Tokka and Chompy were gone especially Rapheal but relieved when the little guy hitched a ride on his shell.
Earth's Last Stand: He made a brief appearance standing on Raph's shell worried that he wouldn't comeback until Raph assured him, he's not going anywhere.
Tokka vs. the World: The turtles discover that Tokka is still alive and heading to earth looking for Chompy. Raph who was heartbroken had to return him as he knew it was the right thing to do, so they use a Kraang ship to return him after Raph explains to Tokka what happened. The two go their separate ways but Tokka stops them and allows Raph to keep Chompy and with Tokka back in space. Back at the lair, the gang discuss what will Raph do when Chompy grows to full size the earth won't be big enough to hold him. Realizing that he understood that Chompy would return to the stars one day but it would be a great while before that happened.
