Okay got him!
Initial reaction: COOL.

Alright first off I had a disappointment. His left leg joint was broken, the pin up in there seemed to sheer off. One strike against.

Okay besides that...
Appearance:The figure is awesome.
Well done detailing, he looks right out of the comics. I think the dark lines that denote musculature and wrinkles should have been a dark green, black is sort of odd but it does help with the comic book look of illustrated lines. I love that his head is textured skin.

Watch the kneepads, they're not full wraparound straps, they're broken in the back for posing purposes, you'll have to glue them back on if you pull them off!

His sai I'm happy to say, fit into his belt on his sides, IMO the way it SHOULD BE!
Not on his front so he couldn't walk right.

And I'm happy they got TAILS!
Articulation:Joints can be delicate, like the left leg ball joint that was broken right out of the box. I hadn't even touched it yet and saw how loose it was.
Everything else seemed to move fine, he can hold zai* fine & dandy. He is alot of fun to pose, no doubt about it. There are joints where most average figures could only dream of. I like that they put a joint up in the head and then at the lower end of his neck, so you can move them anyway you want. Watch the shoulder joint, Cyn's Leo came out with the ball turned the wrong way so be careful turning it the right way and watch those legs at the hips.
Extras:
His hands pop off and you can pop on his climbing hands, I think they're called shuko?

The best extra is the turtle baby. OMG it is so cute! It's like the size of a hatchling spotted turtle. Those little grey things by the laptop are his throwing knives.

The diorama is nice and detailed as well, as you can see in the top image. I won't be surprised if the first wave sells out fast, overall this is the ideal adult TMNT figure.
With this leg issue I've emailed NECA hoping they are willing to replace the figure.
*zai = plural for sai. yes this is true.
