Why did the Kraang hide?
 

After BFNY why didn't the Kraang directly come back? Did they think they were outmatched? Was their Mutagen supply diminished? Its hard to believe that an alien race with attack ships, massive terraforming warships, and portal travel would back away from some turtles.

I guess the humans would try to hunt them down?

I do not understand what you mean by BFNY.

Battle for New York.

Well, after battle of new york, the kraang had a lot of enemies, powerful ones. The turtles themselves were bothersome to them. Not to mention there was alsothe mutanimals with That dude the turtles met a while back( forgot his name). He knew a lot about the kraang. Heck they were even looking for him in the beginning of the show.

I think there are two reasons. 1) To repair the technodrome. 2) Give the Turtles the element of surprise.

"That's (teenage) mutant ninja turtles Sparky." Plus, they're just that good. :trazz:

i can almost hear subprime. "because you humans had boards with nails in them! you ever been hit with one? its how i lost my eye."

The person you are thinking of is Kurtzman.

Thanks, angel. It was on the tip of my tongue, yet I couldn't remember. I hate that.
