Episode Summary

The Return of Dregg
The Turtles are working on once and for all ridding themeselves of thier mutations, Donatello makes use of a Virtual Reality Programm to test out the effects of a potential cure he has created using the Vortex Crystals. On his homeworld, Dregg schemes to return to Earth, his chief scientist, Mung presents the micro-bots capable of creating advanced machinery in seconds rather than days or months, as well as track down the Vortex Crystals presently being used on earth.

Back on earth, Donatello tries out his cure on both himself and the rest of the TMNT for real. It works, well, at least on MOST of the green machine, one of the micro-bots Dregg sent to Earth to find the vortex crystals, has located the source at the lair. Unseen, it steals one of the crystals just as Leonardo receives treatment for his own mutation. The experiment goes without a hitch, and Leonardo seems fine until later, when he suddenly mutates and goes on a rampage across New York.

April, Investigating a recent power outage at the Hydroelectric dam, stumbles onto Dregg (having arrived on Earth VIA his ship the Dreggnaught) and discovers he is using the Microbots to create a dimensional transporter, she contacts the Turtles, but she is caught by Dregg. After a dramatic chase, The TMNT are able to capture Leonardo, and they set out to rescue April, in the ensuing battle, the Turtles are tricked and captured by Dregg.

Before the TMNT can be used as guinea pigs in Dregg's dimesional transporter, the mutated Leonardo bursts out of the Turtle Van and tears the place apart. Dregg and Mungg escape in the Transporter before it explodes, and the TMNT escape the factory as it collapses completly, but although April, and the day, has been saved, Leonardo is still mutated, and Dregg is still at large...

    Even though this is probably my least favorite episode from Season 10, it's still a cool episode, and starts off the "5 part" mini series. I love how the mutated Leonardo throws that giant cyborg into space. That was awesome! The fight scenes were at it's best in this season, as well as the story line. Though, it probably wasn't WRITTEN as well as the earlier seasons.

Trivia, Notes, Quotes and Allusions


  • TRIVIA (1)

    • From this episode onwards, Mung is Dregg's second in command, and Hi-Tech gets blasted into space to orbit the galaxy. (Needless to say, this is Hi-Tech's final appearance as well.)

  • QUOTES (7)

    • Raphael: April, it's Raphael!
      April: What's up?
      Raphael: Leonardo's mutated out of control! He's doing a King Kong routine for the local news. Can you pull the plug on the story?
      (April checks computer)
      April: Hmm, let's see. Oh, sorry guys, it's a live feed.
      Raphael: In that case, how about calling the department of animal regulation?

    • (While mutated Leonardo is destroying the city)
      Donatello: Raphael! Call April, and see if see can keep us off the 11:00 news!
      Raphael: Oh sure, give me the impossible job.

    • (Mutated Leonardo destroys traffic light)
      Raphael: I sure hope our insurance covers mutant damage!

    • Donatello: It's a good thing we ran a virtual reality simulation on that de-mutation ray, before we tried it on ourselves.
      Raphael: Look on the bright side, guys: we could make a bundle selling that as a video game!
      (Raphael puts de-mutation simulation glasses back on) Can I play it again?
      Leonardo: (sternly) This is no joke, Raphael.

    • Leonardo: (Talking to a mutated Michaelangelo) Come on, Michaelangelo, snap out of it!
      (Mutated Michaelangelo extends his claws)
      Raphael: Just our luck, a Swiss army mutant!

    • Dregg: Place these fools on the transporter with the girl.
      Donatello: Hey, where are you sending us?
      Dregg: The center of The Sun.
      Raphael: Aww. And me with out my number 50 million sunblock.

    • (Dregg is about to blast Hi-Tech into space)
      Dregg: I'm sending you on a mission Hi-Tech, you are to orbit the galaxy and return with untold data in 2000 light-years...
      Hi-Tech: Lord Dregg..No!!......
      (Hi-Tech gets blasted into space.)

  • NOTES (4)

    • As of this episode, Michael Gough (II) provides the voice for Raphael. Since Rob Paulsen was not around to voice Hi-Tech (even though his appearance was quite brief), Cam Clarke exclusively voiced him.

    • This was aired alongside the next four episodes in the U.K packaged as a "Feature-Length" movie around November 1999 on Fox Kids, the "Red Sky theme" was glossed over the title sequence by the U.K "Teenage Mutant HERO Turtles" theme
