Mega Bloks idea.
 

Invisibility is impossible. But here's an idea how Mega Bloks can make The Foot TECH Ninjas with their disappearing act; Make two mini figures, one a visible Foot TECH Ninja mini fig and another of the same features only made out of transparant plastic so you can see through it.

First, it's TECH. As in technology. Not TECT. Secondly, that's pretty much the same idea that's been kicked around for the action figure version of the Foot TECH Ninja.

I just type fast, see my edited post.
