Got both now, they're smaller than they look on the pics, but still awesome nonetheless. Gurren Lagann comes with two heads, two parts for the face with sunglasses and no sunglasses, four different hands, jumbo throwing sunglasses, and a Giga Drill. You can pretty much take the whole thing apart and put it back together, awesome, but.....
The Lazengann is straight sexy, I wanna fuck it and fuck it some more, it comes with two of those drill thingys that come out of it's body, two parts for the face with teeth and no teeth, and four different hands. Also, it comes with two parts for Gurren Lagann's Jet Pack thingy, guess that's the incentive to buy em all, meh.
Oh, and they both come with these stand thingys, but they're pretty lame.
