Confirmed villains returning list
 

So aside from new villains Nick has confirmed:

Shredder
The Foot
Baxter Stockman
Leatherhead
The Rat King
Karai
Metalhead

So I guess Nick is bringing back all the major old characters. Depending on if you view The Kraang as a fusion of Krang and the Utroms that's another.

I hope to later on see the Triceratons and Hun, but this is a good starting list of old classics.

Um...is Leatherhead confirmed as a villain?

If I remember the toy sketch had a Foot symbol on Leatherhead. He might start off as a villain and then become good.

Leatherhead was confirmed in a photo of toys that are sure to be second wave of the upcoming Nick show line. Along with Baxter Stockman in a battle suit,Metalhead, and those three new mutants.

Rat King has not been confirmed though or even hinted so I am not sure why he is on the list.

Metalhead is not a villain. I always thought of him as a good guy. It depends on a simple rewiring so you might be him as a neutral until we know which sdie he will end up on.

Rat King was confirmed by the two folks who went to the event in the UK. And of course Metalhead is a villain, what kind of question is that?

I Hope Leatherhead isn't a villain, I've always preferred him as an allay

When it comes to good and evil robots Metalhead comes to mind for good and Chrome Dome for bad. After Don reprogramed him he was good so I would not classify him as bad. We will have to agree to disagree,my friend.

Thanks for the heads up about Rat King. Are there any pictures? I just hope he will be a human who is the #2 foe.

I could be wrong but I believe there was an article a few months ago confirming that the Rat King would be a part of the new series.

i wonder if bishop will show up in the 2nd season

So far none of the 4kids-created characters seem to be in it. I do want to see Hun eventually though.

i'd be really confused if leatherhead wrks for shredder n kicks the turtles butt...and rat kings a clone of stockman....

Where are the images of the three new mutants? I... can't navigate at all through all these threads to find anything.

I don't really like the new mutants designs or names so far, but I'll wait to see them in action.

When Old Hob was first announced I wasn't keen on the idea of a mutant cat as a major character, but he turned out wonderfully. I really hope Old Hob winds up in Season 2 of the cartoon.

I'm definitely looking forward to Leatherhead and the new mutants. Though I would still like to see Bebob and Rocksteady make appearances at some point. Even if it's just long enough for both of them to get action figures.

I'm not sure if I would count Metalhead as a villain just yet. He could just as easily be an ally. At least I don't think they've said anything about his allegience yet.

I really couldn't care less about Rat King. Though who knows, maybe this show will finally make him interesting to me.

Is that bit about TRU being the only retailer committed to the Classic Collection line true? That's the first I've heard of that, and I REALLY hope it's not true...

i wish klunk would come back one day as a mutant

I prefer Klunk as being a normal cat, but that's just my personal opinion.

God, those three-toed toys look terrible. Why on earth did they decide to do that?!

Where? I don't see a symbol on him.

But Leatherhead could be a villain, if they use his original origin he could be rised by The Kraang instead of the Utroms.
