Madame Odius

Madame Odius is a sly kitsune-themed alien who is first seen as Galvanax's advisor until she is revealed to be the true main antagonist of the Ninja Steel seasons. She is seen to possess a hammer-like object capable of performing magical spells. She and Ripcon accompanied Galvanax where they fought Dane Romero. When he suddenly disappeared during battle, she was present when Galvanax made off with Brody.

10 years later, Madame Odius pitched an idea to Galvanax in order to make new stars upon acquiring the Ninja Steel. Galvanax doesn't know, but Madame Odius plots against him and had successfully obtained the Gold Ninja Power Star. She begins by doing an experiment on it in a secret room on the ship with a civilian that she captured, a country singer named Levi Weston, whom Madame Odius captured in the same time after Levi pulled out the Gold Ninja Power Star from the Ninja Nexus Prism. However, the Astro Zord found and rescued Levi and escaped to Earth while after taking the Gold Ninja Star along with it to becoming a Gold Ninja Steel Ranger.

Madame Odius later created the Aiden Romero Robot using Levi Weston's memories of being Aiden Romero in order to get close to the Ninja Steel Rangers' base. Upon the robot's destruction, Madame Odius pinned the blame for its creation on Ripcon.

In "Galvanax Rises," Madame Odius ropes in Victor and Monty into building the Mega-Magnet to help her in destroying the Rangers and Galvanax. Upon Galvanax being enlarged, Madame Odius activated the Mega-Magnet to attract every Ninja Steel present including the Ninja Steel ingested by Galvanax as Madame Odius reveals her motives. However, the Ninja Steel meteor is also attracted as it strikes Galvanax' ship which sends it flying far into space. Though Madame Odius survives the unexpected meteor strike as she states that it's not over yet.

In "Echoes of Evil,” She and Cosmo Royale encountered Sledge and Wrench who escaped from a blackhole and wanted the Ninja Super Steel Meteor in the Warrior Dome's ship. In exchange for the Ninja Super Steel Meteor, Sledge will repair the ship. Madame Odius allows Sledge to repair the ship where she gained Badonna as a servant. Then Madame Odius plans to have Cosmo Royale begin the new season of Galaxy Warriors.

When it came to the Galactic Ninjas, Madame Odius managed to salvage Wolvermean's Ninja Medal to further her plot. Then she salvaged Speedwing's Speed Star upon his destruction. Madame Odius tells Badonna that she has plans for them.

After Rygore's death by the Rangers, Odius claimed his medallion and she is later approached by Badonna, Venoma and four Foxbots. She then took her Ninja Medallion which is used with those of the other Galactic Ninjas and her Foxbots to help create her Megazord Foxatron. After defeating the Rangers' Megazords, Foxatron ran out of energy. Madame Odius threatens Venoma, demanding an explanation for what happened. Venoma states that the Ninja Medallions just need to be recharged and by tomorrow at the same time the Foxatron will have enough power to destroy the Rangers once and for all.

In “Outfoxed,” After Foxatron was recharged, Madame Odius uses it to destroy Wolvermean before facing off against the Rangers. The Ninja Blaze Megazord destroys Foxatron with the Ranger Blast Final Attack forcing Madame Odius, injured at her face, to retreat with Badonna and plan her revenge.

In "Magic Misfire" after Tynamon kidnaps Mick and brainwashes him, Odius launches her final plan that involves a brainwashed Mick building a satellite to boost the power of her mind-control device.

In "Doom Signal" despite Brax's death, Odius succeeds in her ultimate plan: using her mind control device to brainwash all the humans, including Calvin the Yellow Ranger except the others Rangers, Redbot, Victor, and Monty. She plans to use the humans as her personal army to conquer the universe.

In "Reaching the Nexus", when the Rangers thwart her mind-control plot, Madame Odius manages to absorb the powers of the Ninja Nexus Star and assume a Kyubi-like appearance that grants her enhanced strength, combat prowess, increased magic attacks, and endurance. Odius is no match for a whole team of those with equal powers to hers, falling in the final battle when the Rangers combine their Power Stars with the Nexus Power and bringing peace to Earth.
