Toy customizer Donald Kennedy aka KodyKoala made this Mario Mech out of a Merio vinyl figure, a Mario Keychain, and some parts taken from a toy mech from that Avatar movie. The dirty brushed metallic finish is awesome and the bolts are a great touch. Hopefully he does some more Nintendo mechs. Donky Kong, anyone?

About the piece, KodyKoala says:

This was something that my brother and I have been talking about for a while. We thought it would be cool to have Nintendo characters drive a mech of the themselves. This is the first of a series. I love the way this came out, and it is pretty self explanatory how it is made, except for the cockpit, which I got from and Avatar Mech Amp Suit. I am also trying a cool new background as well as better lighting, so the pictures come out crisper.
