In the 1987 cartoon, Traag (voiced by Peter Renaday) came following the Neutrinos through the dimensional portal. After a small skirmish with the turtles, the Neutrinos teamed up with them and Michelangelo and Donatello sent both Traag and Granitor back through the portal and to their own dimension. Traag would make further appearances in the series until the eight season finale "Turtle Trek". As "Turtle Trek" ended with the Technodrome stranded in Dimension X it can be assumed Tragg is still in Dimension X somewhere.
