The Technodrome wasn't completely doomed
 

I still think Shredder and Krang could have used Dregg's nanobots to rebuild the Technodrome and its engines. And the turtles only saved Earth. Dimension-X still belonged to Krang. His rock soldiers were everywhere. Krang won in the end.

Divide and Conquer proves this; there are still a few soldiers in the Technodrome; but Shredder and Krang probably took a vacation somewhere and forget to have a sensor for the Technodrome to track the turtles. If the show had a Season 11, I easily could have envisioned a Super Shredder scenerio if S&K (a bit of trivia: I believe that in the episode Burne's Blues, the S&K Nutrifreeze van stood for Shredder and Krang) had found the proper materials to repower the technodrome. I also assume Bebop and Rocksteady are lost somewhere as well.

I find it funny that there is no indication if General Tragg and the Rock Soldiers ever stopped attacking the Neutrinos.

For all we know, the war between the Neutrinos and the Rock soldiers would continue for years to come.

or even some technology of Krang's even

i like that

yeah for sure

The microbots could have easily rebuilt the Technodrome. It was just as damaged after The Big Blowout and in the end, the Technodrome ended up being repaired, even without the help of the microbots.

they could rebuild, make it bigger, faster, stronger! :P

Well, Turtles Forever pretty much not only confirmed they got it up and running again...they ended up with an improved model by the movie's end.

I always figured Turtles Forever took place in Season 3, hence the Technodrome being underground, the Channel 6 building still standing, and April being in her yellow jumpsuit.

Its not unusual that Krang would want to remove all the Utrom stuff and turned the Technodrome back into what it once was.

Yeah, I as well assumed that the original toon's characters were supposed to have been from some time around season three.

That's why we're still meeting here for our TMNT discussions. ;)
BA DUM PSH.
