The second season of Nick's Teenage Mutant Ninja Turtles is nearing its end and the big finale was promoted at San Diego Comic-Con with an exciting new trailer! Shredder takes on Leatherhead; a Kraang invasion; and Leo's in trouble! There's a lot going on in this trailer, so instead of talking any more about it, we'll let you go check it out for yourself!

The season finale will air this September. So, what was your favorite part of the trailer, TMNT fans? Don't be shy, chat about it below!

September you say? This is gonna be one hell of a birthday present!

that's okay she can show up in season 3 and 4 more bad ass than ever

Yes Leo gets that thrown window scene

I'm calling it. Beebop and Rocksteady are going to appear in the finale, like at the final scene

They had me at Shredder vs Leatherhead

And I thought the finale trailer for last season was epic.

I mean, Leatherhead returns, lots of epic fight scenes, Gilbert freaking Gottfried!

I guess Shredder just wants to watch the world burn.

Was that...Gilbert Godfrey? What the heck is Gilbert Godfrey doing here? And man was that an epic trailer. I thought Season 1 ended on a high note but this is like ending your tour at Madison Square Garden to a packed out audience.

This looks intense. It's great they can add this kind of emotion to a kids show and make it interesting to everyone.

Anyone know when it's supposed to start up again? And is the finale the only episode(s) left in season 2?

After the whole thing with Karai, she is not involved here ?! I mean come on, that is one of the most important plot-points compare to alien invasion.

They better involve her somehow O.o

I'm excited for the Leatherhead/Shredder fight.
