Hello folks. Personally I think the Underminer is awesome and I also wanted to draw him. Unfortunately I haven’t been able to get a good picture of him. I was wondering if anyone had some concept art or renders of this guy they could share with me so I may have reference pictures. I hope someone out there does. If you don’t wish to share publicly, send me a PM with the stuff I need. Thanks for reading!
I can’t find any concept art for the Underminer, but I have found a picture of John Ratzenberger with an early drawing of the Underminer.

Oh, cool. That’s a nice find. So uh, anyone else got any pictures of him? Or is there a way I can contact pixar and ask them for one?
Also I’m looking for a render of Syndrome, high quality, if you don’t mind.
Well, I would try google searching for what you need. But if you can’t find anything you need, I would contact Pixar.
Grendor- I had a look around and couldn’t find any concept art of the Underminer, but perhaps if you have The Art of The Incredibles or if you plan to get it, that might be a good place to look? I know it’s an expensive book, but if you’re a big fan of The Incredibles, it should be worth it.
The only Underminer piece in The Art of the Incredibles is a collage by Teddy Newton (famed for collaging many other character designs.) It really hard to tell, but it looks like it’s on the board behind Ratzenberger very out of focus. I can scan on demand, if you so choose.
My question concerning the Underminer is if he would be present in a possible sequel to The Incredibles? I mean if I got it right, he was featured in The Incredibles video game, right? So does that mean that he’s not a possibility? 
In a sequel, I doubt that he would be in it. (Maybe the fight between TI and the Underminer could be the opening of the movie to get Ratzenberger’s voice in it)
