Giant Bot

This Giant Robot (No official Name) only appears in Episode 23 where it needs to destroy the Enchanted Forest to find Argaï and Barnaby. They walk slowly, but are able to crush big trees and set the forest on fire using flamethrowers attached to their arms. Eventually they're all diabled by the magic power of the Fairy Melusine, who activates a heavy thunderstorm to hit the Robots, and rain to put out the fire.
