This Mecha is the most advanced project of my creations because I have tried to follow the slightest details from the original drawing. In the head that opens from the top, there are two minifigure-clones, whose pilot the robot and the other handles his fearsome weapon: the mechanic saw-mace (which works in real life through the gear !). In the hips are two clones fighters armed with small mechanic saw-maces. This terrible robot has enough of joints to be able to adopt all positions to fight his eternal adversary the Samurai.
