Gresh has the same Av-Matoran build as all the other Stars, except a bit of armor: new armor. This claw-like armor can be found only in this set, which is another reason to get it. Gresh stands out also because of his lime green pieces, a pleasure to the eye.
As I said above, Gresh has some interesting pieces. Half of this set is either recolored or new, which is great. He has a new lime green mask, my favorite mask ever. The color scheme fits well on him. He also has new claw-like armor, and a recolored sword, Glatorian fist, and exterior.
Gresh is a cute little character to play with. The other Stars make it fun for battle scenes with him, the weapons are awesome, and he is kind-of poseable.
