King Mondo

King Mondo (voiced by David Stenstrom) is the ruler of the Machine Empire and the main antagonist of Power Rangers Zeo.

Driving Rita Repulsa and Lord Zedd off the moon, Mondo believed the Earth would be an easy conquest, but was shocked when his army of Cogs was repelled by the Zeo Rangers. Intrigued by the idea of being challenged in a conquest, Mondo decided to take his time trying to conquer Earth, as he had gotten bored of the easy takeovers of other galaxies.

However, Mondo soon grew tired of the Rangers, who repeatedly thwarted his plans (some successful, some almost successful, some not). The conquest of Earth was made even more difficult when the Gold Ranger arrived and bolstered the Zeo Rangers' ranks, despite repeated efforts by the Machine King to take the Gold Ranger's powers for himself. Mondo finally tired of fooling around and unearthed the ancient Sword of Damocles, intending to personally destroy the rangers. He grew giant and confronted Earth's defenders, but was vanquished by their new Super Zeo Megazord.

Despite this victory for the Rangers, Queen Machina expressed confidence that Mondo would be rebuilt. During this time, the Royal House of Gadgetry had to deal with potential usurper Louie Kaboom, who tried to woo Machina but eventually placed her and Prince Sprocket under arrest and ruled by decree. Mondo's first son Prince Gasket soon arrived with his wife Archerina, took care of Kaboom, and then took over themselves.

King Mondo returned to the throne shortly after chasing away the two. He clashed with the rangers in battle with his new monster Cog Changer. When Rita and Zedd threw down their gauntlet and sent down their own monster, Mondo asked them for a temporary alliance and merged the two monsters, but this plan failed. After a failed attempt to steal the Gold Ranger Powers again, the Royal House of Gadgetry met with Rita and Zedd on the moon to strike up an alliance. However, they were double crossed as Rita and Zedd's "surrender" gift was actually a bomb. Mondo and his family were blown to bits but Mondo survives, though he is badly damaged and swore vengeance.

Mysteriously rebuilt once again, King Mondo attended Dark Specter's conference on the Cimmerian Planet with his wife and was present when a mysterious red ranger crashed the party. Months later, he teamed with General Havoc and led the Machine Empire in invading KO-35 and the Phantom Ranger's homeplanet. When Zordon's energy wave struck, King Mondo was reduced to a pile of sand, destroyed forever.

Years later, General Venjix, the leader of the Machine Empire remnants, still looks up to his former king as a living god over creation. Before his destruction, he is sad that he has failed his king years after the Machine Empire fell. King Mondo is mentioned by Venjix, as he shows to his minions a statue of him.

True to his name, King Mondo acts very much like a king or an emperor, he is a ruthless entity that will do anything in his power to destroy the Rangers and rule the Earth, despite this, he is loyal to his monster creations (valuing them as his equals) and is good terms with his family, as well as his servants Klank and Orbus (even so, he does occasionally boss them around a little). He loves his wife and second son dearly, but is on shaky terms with his first son due to the fact that he married the daughter of his sworn rival King Aradon.

He loves his second son Sprocket so much that on his birthday he and his wife gave him Wrecking Ball as one of his birthday presents.
