Ivan Ooze is a character from "Mighty Morphin Power Rangers: The Movie," released in 1995, and he is not originally from the TV series. However, some of his backstory and actions were referenced in the context of the series.
In "Mighty Morphin Power Rangers," Season 3, the storyline involves Rita Repulsa and Lord Zedd, who are the primary antagonists of the series. They may have used Ivan Ooze as a plot device to introduce new threats to the Rangers. His character was portrayed as an ancient evil who had been imprisoned for thousands of years, and upon being released, he sought to take revenge on the Power Rangers.
Ivan Ooze's appearance helped to create a fresh dynamic in the series, as he posed a significant threat due to his unique powers and abilities. Rita and Zedd initially allied with him due to his power, which added tension to their existing rivalry and set the stage for new and exciting developments in the series.
The mention of Master Vile refers to an even later character who appears in Season 3, specifically in the "Alien Rangers" arc. Master Vile is a significant antagonist who creates further challenges for the Rangers after the Ivan Ooze storyline. The introduction of new villains is a common trope in long-running series to keep the storyline engaging and to introduce new powers, conflicts, and character developments.
In summary, while Ivan Ooze himself doesn’t appear in the Season 3 episodes of "Mighty Morphin Power Rangers," his character was utilized in the movie to create a connection between the series and the film, enhancing the narrative's tension before transitioning to other villains like Master Vile.
