So what's the point of showing the monsters still being alive at the end?
 

So the show is kind of infamous for introducing characters that never return or at least don't come back in any meaningful way. The Turtles battle all these monsters and nearly every time they're shown to still be alive at the end, promising a follow up that will never happen.

What is the point of that? It just creates more and more unresolved plotlines, it's pretty frustrating to be honest. Think about it, what does this actually imply? Look:

1. Snakeweed is still probably trying to eat people
2. The cockroach thing may very well regenerate
3. The Newtralizer is still alive (granted, he'll probably come back)
4. The mushrooms are still around
5. Pizza face was ultimately proven to be real in the Mondo Gecko episode
6. The Creep was implied to regenerate
7. The Chimera is still haunting Northampton

So why even imply their survival if they're probably not going to come back?

Cause it's a children's show.

Because (hopefully) the writers are focusing on more important plot lines like Karai and Shredder and not so much the characters people dont wanna see. Characters like Newtrawlizer get extra episodes with characters like Slash because we the fans wanna see those characters more so than we wanna see Spider Bytez or Cockroach Terminator.

Showing them still alive means that they will come back eventually even if it may not be right away.

I don't know about you, but I think the Creep and Chimera will team up.

Na, it should be Creep and Dream Beavers teaming up but then they turn on each other referencing Jason vs Freddy movie. :lol:

Preeeeetty much. And so they can bring them back whenever they feel like it.

Spyderbitez and snakeweed are great original creations so I am glad they are still around. If cockroach terminator shows back up I hope he is in his original form and not what he was right before he died

So they can be ready for new episodes, easier to sell toys if they aren't de-mutated and forgotten...

So they can maybe use them again when they don't feel like making another villain model?

Yeah, it's cheaper to reuse...

Its hardly a problem exclusive to TMNT though :) I mean how many other superhero series (live action or animated) will forget to finish off their villains?

It generally only happens in movies (and even then....)

Same with many comic books about heroes and superheroes.

I like how the only villain who's more or less dead is the Rat King.

And by like I mean ugh.

Yeah. That way the writers can bring the characters back if the plot calls for it.

It's actually pretty bleak when you think about it. Some of these guys came really close to killing the turtles, who just barely defeated them....and they can't ever die. They're still out there killing dozens if not hundreds of more people while the turtles have their back turned, fully unaware. (You saw those skeletons in the Chimera's nest.)

It's like a neverending battle.

Also, it may (hopefully) come a day at the end of the series (or mid, befoere a new main-storyline replaces mutations) when the TMNT are able to cure most mutations.

Does it matter now when the show is still young? If we were in Season 7 and villains kept coming back with no closure I would agree, but now in Seasons 1-2?

For example Rockwell disappeared after like the 8th episode of the show and didn't reappear till part of the Mutanimals much later on. Some characters can go gaps without reappearing.

Some of them do get used again once or twice.

They want to turn them back to normal for a happy ending for them (especially Timothy). It also effectively kills the animal-to-monster ones by making them just normal animals, so they don't really die.

I assume so that the toys are more likely to sell. Also, so that they can use the character again. In addition, like others have said, cause it's a kids show.
