Started working on this guy the other night. The base model is Genesis 3 Male with Joe Quick's Turtle Power for G3M. Elbow and Knee pads are from Joe's earlier TrtlPWR set for Genesis. bandages are from M4 Bandages by Evilinnocence. The mask, belt harness and weapons are extracted from FoRender's TMNT LEO.
The mask was extracted from the TMNT LEO model, deformed to fit my Leo's head and then simply parented, it also retains the separate bones for the tails for independent posing. The belt harness was also extracted, but due to its positioning it required a lot more deforming to fit the turtles shell. Unfortunately, since I've learned shit-all about rigging, I've simply parented it to his upper abdomen, which really limits his upper body movement.
Planning to do all four Turtles. Which means I'll have to extract the other belt harnesses from the FoRender models. Luckily won't have to do the masks, since a simple color swap will be sufficient.
