Took me some time to begin but here is how is looking. Now this is a totally different exosuit from the original Krang. I wanted to make him look stronger, even though he doesn't fight at all, but you have to be prepared always when you have the turtles as enemies.

I still haven't decided if I should go with 2 or 4 legs. I'll decide later.

Anyways, this Krang is going to look good!

But I didn't stop there. My plan was to do the whole thing. So, I went ahead and started redesigning the whole robotic body. This is how it turned out.
I was kinda satisfied with the design so I proceeded to model it. Here is how is looking so far. This was done in 3D Max, is not textured yet, and probably I won't texture it.
I wasn't happy with this robot. So, I went back to redesign the entire body. This is how is looking far.
Now I am happy. Yes, I think this one will work.

I have always been a fan of the Ninja Turtles, and for some time now I have been thinking on redesigning Krang.
Yes, up until now I haven't seen anybody model the poor villain. So, I went ahead and redesigned the guy. I went for a similar look from the cartoon, but in the cartoon he was a pink thing with no shape and tentacles. So, I said, to me, he was always a brain. And so, I went for that look. A pink brain with a face and tentacles.
Done in 3D Max, and later in Zbrush. Textured with photoshop. Voila! A new and improved version of Krang! Enjoy.
