These tmnt heroclix are made from imported china tmnt plastic minis I got on ebay and can no longer find. They didn't come with weapons so those were made with nails, plastic, and fodder. I gave them a black wash to dirty them up a bit and glued them on actual heroclix bases that coincide with each turtle

I think their bases work well. Look them up for more details. My major requirement for them was they each HAD to have stealth. What heroclix base would you use for the tmnt? Let me know. All comments are welcome and appreciated!
