Cyclopsis

Cyclopsis, a giant evil zord piloted by Goldar—and arguably the strongest enemy the Power Rangers had faced in the first season—was summoned as a War Zord, apparently used 10,000 years ago, when Rita had launched an earlier attack on Earth before becoming imprisoned in a space dumpster. He was destroyed by Ultrazord twice.

Cyclopsis easily beat up the Megazord. The Rangers tried calling the Dragonzord, but it was no help, and even Dragonzord Battle Mode was easily beaten, weakening it quicker than even The Spit Flower and the Samurai Fan Man were able to. Seeing the situation, Zordon summoned Titanus (which blasted the zords free of Cyclopsis's arm cables) to form the Ultrazord. The Ultrazord's arsenal was too much for Goldar's warzord to handle. Cyclopsis's head survived and flew to a distance.

Soon, Rita summoned Lokar, who quickly rebuilt the War Zord, adding wings and wrist mounted swords, who easily overwhelmed the Megazord and Dragonzord again, this time slicing off the Megazord's arm and half of the Dragonzord's tail, When Lokar joined the battle, it only made things even worse for the Rangers.

The Evil Zord possessed physical strength far exceeding any season one Megazord combinations including the MegaDragonzord and carries a number of weapons, including deadly twin multi-rocket launchers mounted below his neck, a powerful eye laser, and hands attached by cables when they shoot out, which can deliver electric shocks through them to damage his opponent. After being rebuilt by Lokar, Cyclopsis didn't use any of these weapons, but solely relied on twin blade gauntlets mounted on his arms.

After linking to Rita Replusa's computer systems while her Lunar Palace was on Earth, Alpha discovered that the only weakness in Cyclopsis was that its systems needed to adjust to compensate for battle with a new opponent, and too many changes in the enemy would cause it to freeze up.

First, the Rangers attacked Cyclopsis with their individual Zords (with no success) and then the Megazord, which was again overpowered. The Dragonzord was then summoned, and was able to break Cyclopsis's blade gauntlets. The Rangers attacked with the Dragonzord Battle Mode, which took the upper hand because Cyclopsis was apparently ready to freeze up. However, Lokar joined the battle again, blasting the Rangers, which forced them to summon Titanus and form the Ultrazord before Cyclopsis could adjust and pummel the Dragonzord Battle Mode like it did in the first battle. Cyclopsis froze up completely upon this opponent switch, which left him helpless when Ultrazord destroyed him permanently. Afterwards Rita fled the battle by command of Goldar (who temporarily gained more power afterwards, almost like a top general or a quartermaster). It has been speculated that because Alpha and Zordon hacked into Rita's database, and Rita found out, she was forced into alternative methods of monster making (such as planting seeds and transformation of objects) until Finster had fresh monster ideas.

Cyclopsis appears as a boss in the SNES, Sega Genesis, & Sega CD versions of Mighty Morphin Power Rangers.
