The Machine King is evil personified. He is very sophisticated and always in control. He rules the Machine Empire with an iron hand, and wants to do the same with Earth! He wants ever more machines and humans, ever more worlds under his thumb. Too much of a good thing is never enough for this terrifying tyrant!
After finding the Sword of Damocles, Mondo used it to grow to giant size. He then took on the Rangers in battle, but he was destroyed with the power of combined Super Zeo Megazord Swords. He was then taken back to the Machine Empire in pieces, and slowly rebuilt.
