The Mighty Morphin Power Rangers participate with Bulk and Skull in a charity skydive for the Angel Grove observatory, in anticipation of Ryan's Comet which is scheduled to pass by in two days. Bulk and Skull miss the target landing zone and accidentally land in a construction site where a giant egg has been unearthed. Lord Zedd, Rita Repulsa, Goldar, and Mordant arrive at the construction site and crack open the egg, releasing sorcerer Ivan Ooze, a morphological being who ruled Earth with an iron fist 6,000 years ago before he was overthrown by Zordon and a group of young warriors.
