NiStuff is a guy who has been working with Matt Doughty and branching off the Glyos universe. He's both created both his own original characters as well as his own versions of Onell toys. The results are quite remarkable, and his booth at NYCC showcased the toys in all their glittery glory.
The sheer amount of product on display was staggering.
Bins were overflowing with various custom heads.
The custom work extends beyond the standard PVC figures and applies to Vinyl as well.
