The problem with making miniatures of the Tron: Uprising cast is that they all pretty much dress the same: black or white skin-tight outfit with circuitry lines. The other problem is that glowing LED-like paint is hard to find.
It's an interesting contrast with Tron, who is not as restrained. The differences are clear: Tron is a warrior, Beck is not. But he is willing to fight for his, and everyone's, freedom
For Beck, I used the Heroclix Osiris and added a disk to his back with green stuff. I tried to trace out the circuity as best as I could. The blue circuitry color is a little off though...
