I can imagine a minfig of Roxas fighting that thing in a LEGO Kingdom Hearts 2 game. XD His hair falls off once he uses break raid, he puts it back on, and grabs the Key to bash him. The explosion, is made of white Legos.
Oh, cool, you're using a combination of bricks and technic pieces. That would make the heart-shaped hole a lot simpler. I've tried a couple times but always got hung up on that part because I was just using technic. I did get two good arms put together, and maybe some legs.
Also, haha, replying a year later. Eep. I haven't been on DA in forever.
