Alpha 5 is a multi-functional sentient android from Edenoi who serves as Zordon's trusted robotic assistant, responsible for the daily operations and upkeep of the Command Center.
[7] Prince Dex/Masked Rider is a warrior from Alpha's home planet of Edenoi who leads a resistance movement against its ruthless dictator Count Dregon, an acquaintance and rival of Lord Zedd who is also Dex's uncle.
However, he often goes to Earth when there is no fight going on, because his main duties are acting as a spy and saboteur, as shown in episodes like "Switching Places", "Foul Play in the Sky", "Calamity Kimberly", and "Rita's Seed of Evil".
In "Rangers of Two Worlds, Part 1", Finster makes a new Staff for Rita which is absurdly more powerful than the previous one, as it creates a monster that is too strong even for the Zeo Ultrazord.
She was absent during the "Countdown to Destruction" finale of Power Rangers in Space, in which the majority of the series' surviving villains were either purified into human form or reduced to dust.
In the graphic novel Power Rangers: Soul of the Dragon, Lokar is revealed to reside in the Talos Dimension and ceased aiding Rita after the destruction of Cyclopsis.
[19] When he first appeared in the second season of Mighty Morphin Power Rangers, Zedd was quite furious with Rita's constant failures for being defeated by a bunch of children, even after she warned him about Zordon.
Despite his early defeats, Zedd's attack on Earth became progressively more violent and focused most of his attention on eliminating Tommy, whom he saw as Rita's biggest mistake.
Nine years later in Power Rangers Operation Overdrive, Rita and Zedd's son Thrax mentions that he seeks to rebuild his parents' legacy, disgusted by the fact that they were "lost to goodness".
In Power Rangers Beast Morphers, Lord Zedd's staff is one of the many villain relics in Ryjack's collection that is acquired by Evox and his minions.
Zedd was Scrozzle's choice until Robo-Roxy reminds everyone of what he and Rita did to the Machine Empire's Royal Family on the day after Jason returned the Gold Zeo powers to Trey of Triforia.
In Power Rangers Dino Fury, the necromancer Reaghoul revives Lord Zedd at his evilest and used a Compliance Collar to control him due to the Emperor of Evil not taking orders from anyone.
After spending a brief time in outer space, Zedd eventually breaks into Grid Battleforce and frees Scrozzle who retrieves his staff, growing ever more powerful.
Zedd deciphers a signal from the Rafkonian people informing survivors of the Sporix Beast Wars that the planet has been hidden and directs them to its co-ordinates.
In Power Rangers Cosmic Fury, it's revealed that Zedd was freed from his prison on Zordnia by Bajillia Naire, the CEO of Squid Ink Inc, the galaxy's largest and most evil weapons corporation.
However, Bajillia later betrays Zedd and traps him in the Master Captivator, intending to sacrifice him in order to create an evil version of Zordon's energy wave that will wipe out all good in the universe.
In a battle with some Putties, Tommy was knocked unconscious, and the Wizard cut a lock from his hair and turned him into an evil clone, imbued with the restored Green Ranger powers.
When Tommy was revived to full strength, he summoned his White Tigerzord to defend the city, but Dragonzord, energized by the Wizard's evil, soundly beat him.
Rito Revolto is a skeletal monster who is Rita Repulsa's younger brother, Master Vile's son and the secondary henchman for her and Lord Zedd in the third season, often partnered with Goldar and a few times with Baboo and Squatt (whom occasionally were The Three Stooges of the PR verse).
[22] He is famous for his introduction saga entitled Ninja Quest, where he easily and completely beaten and destroyed the Thunderzords by using his far superior weapons and powers.
Master Vile (voiced by Simon Prescott) was the father of Rita Repulsa and Rito Revolto and was based on the character Yōkai Daimaō, the ultimate antagonist in Kakuranger.
Although his monster was destroyed, Vile survived the finishing attacks of both the Shogun and Ninja Megafalconzord, and still managed to retreat despite not appearing to be that badly hurt.
Ivan Ooze was a tyrant 6,000 years ago, until he was imprisoned in a large purple egg-shaped hyper lock chamber by Zordon and a group of young warriors.
He was most angered by the boredom of his lengthy imprisonment, being forced to miss several disasters throughout Earth's history such as the Black Death, the Spanish Inquisition, and the 1981 reunion of The Brady Bunch.
Ivan proceeds to demolish the Command Center and fatally injure Zordon and Alpha 5, leaving the Rangers powerless to morph, fight or even call their Zords.
[15] After rendering the Rangers powerless, Ivan travels to the moon, and betrays both Lord Zedd and Rita Repulsa, trapping them within a snowglobe, much to their dismay.
The battle progresses into outer space, and though Ivan consistently has the upper hand, he is destroyed when the Ninja Falcon-Megazord knees him in the groin, which sends him flying into the path of Ryan's Comet, which happened to be passing the Earth at this time.
In an early draft of the script as well as in some merchandise, he is identified as Goldar's second cousin three times removed on his mother's side visiting for the summer.
They are adapted from the monsters featured in Kyōryū Sentai Zyuranger with the exception of the last 15, which were part of specially created Japanese footage for Power Rangers which fans call "Zyu2".
He would use the grenade for the final time on Repellator in the Season Three premiere and introductory vehicle for Saban's Masked Rider TV series in the three-part episode "A Friend in Need".
