Power Warrior suit Grungy is the Renegade's Power Warrior. The design is the same as Courageous with different colors. The main body can transform into a nifty jet. You can open the chest up and place a GoBot inside as well.
There are four different Power Suits produced. Each is numbered with a sticker. Tonka produced each suit with either a red or a blue sticker. They can clip on to the legs or arms of the main body and be moved around. The weapons and fists (or feet) clip on as well.
For fun facts, the original Japanese ones could fire missiles out of the feet. You can also store the the hands in the feet, through a back door in the foot.
