Thinks you would want returning in the show

[Powder]

I've never been a fan of thinks.

[ZariusTwo]

I'd like Channel 6 to be referenced in a throwaway gag line

[Bossk]

I'd like some totally radical whipped cream pizza, dude!

[Mr.Turtle]

as to reference, i d like they do that to as many things as possible frm the shows in the past so to keep the continuity of universe...

[Genesis]

It's... a different universe. That's kind of the point.

[Mr.Turtle]

just small references wont hurt nothing.

[Genesis]

That's what they're already doing, though. Your concern is entirely moot.

[Mr.Turtle]

we havent seen 1 episode yet n all of a sudden u got everything defined in ur mind abt the show? mook.

[Vincent]

Let's see... things I'd like to see return, that I don't know if they are returning...

From Mirage (not counting the obvious, core things that always come back):
Bloodsucker (more specifically, I'd like to see an adaptation of The River)
Chet (I'd love to see little hints dropped here and there that the kid is still in the city, and grown up, even if we never get to see him)
Klunk
Triceratons
TCRI/Utrom (after having introduced the Kraang, the twist that the Utrom are good guys could potentially be even stronger for viewers not already familiar with the Utrom)
Leatherhead as good and intelligent

From Fred Wolf/Archie:
The Technodrome (it's a cool design, it's iconic, it's huge, and it's called The Technodrome - what's not to love?)
Bebop & Rocksteady (We all know they're more interesting designs than Tokka and Rahzar, although I'd like to see the intelligence quotient cranked up to at least near average)
Ninjara
Irma Langinstein (as a minor character, perhaps April's classmate)

From 4Kids/Dreamwave:
John Bishop
Hunter "Hun" Mason (as Purple Dragons leader, then maybe later joining the Shredder)
Angel
Mr. Mortu
The further developed Purple Dragons (Dragonface, Two Ton, et.c.)
Dheeraj
Garbageman
April's computer skills being somewhat played up (I could have put this in the Mirage list, but I feel like it was given a bit more of a spotlight at 4Kids; Donatello "does machines", but it'd be neat if April helps program them)

Things I don't particularly want to see return:
Justice Force (because I think the idea of superheroes always diluted the importance of the TMNT)
Turtle Titan (mostly because Mikey should have learned his lesson after the first try and never done it again, and now it's been done so much that there's no point even doing it once in the new series)
Ch'rell (because I personally feel it detracts from the dramatic impact of Oroku Saki as a man who made some bad choices)
Channel 6 (or 3, for that matter), and by extension, April as a reporter/damsel-in-distress (because that's Lois Lane)
Cody Jones/Serling
The Ultimate Ninja
April's 2k3 fashion sense (I don't know anything about fashion, and don't really care, but that half-shirt seemed a bit out of place in 2003)

[Mr.Turtle]

its fine if cody's back but not serling.

[ZariusTwo]

If Irma did come into the picture, I'd love Don's affections switch from April to her, just 'cause every old 'toon fan likes to pair those two up.

[Mr.Turtle]

bishop and hun r good choice too.

[Jephael]

To be honest, I seriously don't see those two characters fitting into this new show.

[Mr.Turtle]

^ i do. they r bad a$$ and they r original.

[FearlessLeader]

I just want Klunk

So original that they should be brought back and thus made unoriginal by being rehashed!

[Mr.Turtle]

^well they can always redesign the look of the 2 to make them unrecognizable by the old fans. as long as they are still called bishop and hun.
