Damocles Sword

The Damocles Sword was an ancient, powerful and unstable weapon used by King Mondo when he decided to face the rangers himself. Despite its incredible power, the sword was destroyed along with Mondo.

Past
A 1,000 years ago, King Mondo used the sword in unknown incident, which resulted in his destruction. After being rebuilt, Mondo hid the sword on Earth so he wouldn't be tempted to use it again.

The Return
After Mondo grew tired of his monsters losing to the Zeo Rangers, he decided to take matters into his own hands, and despite Machina's judgement, unearthed the Damocles Sword, believing he knew what he was doing this time. After remastering the sword's power, Mondo used to to grow into a giant. Rocky attempted to fight him on his own, but Super Zeo Zord 3 was no match for the power of the Damocles Sword. After Rocky was forced to retreat, Mondo turned the sword on Angel Grove, his strength growing by the moment.

The Destruction of the Sword
Eventually, the Zeo Rangers combined the Super Zeo Zords to form the Super Zeo Megazord, and, after receiving a final component from Billy, faced off against Mondo. Despite Mondo's boasts that they couldn't defeat the Damocles Sword, the Rangers were able to break the sword with the Megazord's twin sabers before destroying Mondo with the Super Zeo Sword Saber, as Machina thought would happen. Despite this, she assured Sprocket that Mondo would return, more powerful than ever.
