Giant Iron Mecha
From Record Of Fantasy Adventure Venture
A thirty foot tall drivable robot built by Archimedes and currently located in his tomb in Syracuse.
It requires some sort of power source to be inserted in one of seven sockets. Insert it in the wrong power source and there will be a CATASTROPHIC EXPLOSION! At least, according to one M. Tulius Cicero. There is a puzzle which will supposedly indicate which is the correct socket. This puzzle is currently in the possession of the Danger Gang.
