You know what this web site needs? More robots. Without a constant supply of robots, the internet would collapse, and we'd have to go back to sitcoms for entertainment. Fortunately there are people like me out there, who can rely on other peoples creativity to provide us with costume ideas. So without further ado, I present something that's already been done before. A Mr. Destructoid halloween costume. Awesome.
The main cube thing is made out of that foam board kids use for science fair projects, cut into shape and held together by the handymans secret weapon. That's duct tape for the uninformed.
A helmet keeps the whole thing stuck to my head and protects me when I fall down. Two plastic cups and some superglue finish the whole thing off, and spraypaint gives it that metal color.
Throw in a snazy suit an you've got a bad ass costume on you're hands. Should have flashing red eyes in time for halloween, mostly because kids and drunks both love bright flashing lights. Now I just have to work on my robot voice. DESTROY! DESTROY!
