List of episodes

The fourth season of Teenage Mutant Ninja Turtles is split into two main sub-sections that aired concurrently: thirteen episodes which aired daily in syndication, and twenty-six episodes that premiered in hour-long double-bills on Saturday mornings on CBS. Additionally, a two-part "Easter special" aired in syndication the following Spring.

The syndication episodes featured the original title sequence, while the CBS episodes debuted a new title sequence, also did away with the show's title cards, and included a brief "Turtle Tips" segment between the two episodes which served as a PSA about the environment or other issues. There were a total of 20 "Turtle Tips" segments produced and aired.

During this season, the Technodrome is back in Dimension X, having been launched from Earth through a portal at the conclusion of season 3. ^[1] The first syndicated episode, "Plan 6 from Outer Space", detailed how the villains' battle fortress crash-landed on an asteroid; in the first CBS episode, "The Dimension X Story", a volcano on the asteroid erupted, immobilizing the Technodrome by surrounding it with molten lava. ^[2]

Note that the Vacation in Europe episodes take place between seasons 3 and 4. ^[3]
