|This article is about a/an villain in Power Rangers Ninja Steel.|
- "Ladies and gentlemonsters from across the universe, welcome to the Warrior Dome. It's time for another explosive episode of Galaxy Warriors."
- ―Cosmo welcoming the audience to the show[src]
Cosmo first appeared to welcome the audience to the Warrior Dome, Galvanax's base and the stage for the Galaxy Warriors show. He then introduced the next contestants, Lavagor and Korvaka, vying for the chance to try and pull out one of the Ninja Power Stars from the Ninja Nexus Prism and become a champion like Galvanax. After transporting them to the battlefield, he released Buzzcams from under his hat to display the fight. When Korvaka won the battle and returned, he presented him with the Prism. Once the Prism zapped Korvaka, Cosmo informed him that while he didn't win a Ninja Power Star, he did win a trip to the hospital.
Cosmo Royale is shove aside by Galvanax who declares to the audience that whoever destroys the Power Rangers will be named champion. Cosmo later sends Ripperat to destroy Mick Kanic, Calvin Maxwell and Hayley Foster in order to get the Ninja Steel. After Ripperat was destroyed, Cosmo Royale uses the Gigantify on Ripperat to fight the Rangers. After Ripperat's final demise at the hands of the Rangers' zords, Cosmo happily tells Galvanax about how well the show's ratings are doing thanks to the Rangers. However, Galvanax doesn't care about the ratings and vows that the Power Stars will be his, which Cosmo nervously agrees with.
Spinferno is hired by Galvanax to attack the Rangers and the Ninja Steel, Cosmo Royale hosts the show but is interrupted by Spinferno. Spinferno spins around Cosmo Royale multiple times making him dizzy. After Spinferno is destroyed by the Rangers, Cosmo asks the audience if Spinferno should be enlarged for a second chance. The audience votes "No" and Cosmo Royale unleashes a Skullgator instead. After the Ninja Steel Megazord destroys the Skullgator, Cosmo tries to cheer up an angry Galvanax by telling him that the audience loved the Rangers' new Megazord. Galvanax agrees the Megazord is "amazing" but points out it also defeated them. He threatens to throw Cosmo, along with Ripcon and Odious, into the sun if they fail him again.
Cosmo Royale is seen with Ripcon in Galvanax's lair while Galvanax is looking at the portraits of potential contestants including Lavagor's brother and Ripcon's mother. Later, after Sarah Thompson calls Galvanax a "chump", Cosmo Royale asks the audience what they think of the insult, causing them to boo. Later, when Slogre captures the Yellow, White and Pink Ninja Power Stars, Cosmo Royale praises him. After Slogre is defeated by Brody and Preston, Cosmo Royale uses the Gigantify to revive and enlarge Slogre.
Cosmo introduces Tangleweb to the audience. The monster regurgitates a Kudabot it ate earlier, which Cosmo says is disgusting. When Tangleweb absorbs all five Rangers, Cosmo faints with excitement. When Tangleweb is initially defeated, Cosmo asks the audience if they want to give him a second chance. The audiences votes yes, so Cosmo Giantifies him.
When Cosmo reveals Badpipes to the audience, Badpipes uses his power to make Cosmo dance. Later, Cosmo Giantifies Badpipes after the audience votes to do so.
Thanks to a unanimous vote from the audience, Cosmo Royale uses the Gigantify Ray on Hacktrack.
As the audience was displeased that Ripcon failed to defeat Levi Weston, Cosmo Royale unleashes a Skullgator.
As the host of Galaxy Warriors, he is witty and charismatic, behaving like a stereotypical game show host.
Unlike most previous villains and his fellow members, he doesn't seem to have a problem with the Power Rangers being around as long as they boost up the ratings, meaning he prioritizes his show over Galvanax's goals. In several episodes, he openly lauds the Rangers after they win. At the same time, he obeys Galvanax out of fear.
Powers and Abilities
- Buzzcams: Robotic bugs that act as video cameras to transmit the battles that take place between contestants. He keeps them under his top hat.
- Stage Machine: An as-yet-unidentified machine with three buttons each having a different function. The blue button activates the Gigantify Ray to grow the contestants, the red button sends down a Skullgator to Earth, and the yellow button so far is unknown.
Behind the Scenes
- Cosmo Royale is voiced by Campbell Cooley.
- Cosmo Royale's costume is a recycled version of Baron Nero's costume from Ressha Sentai ToQger (which was not adapted into Power Rangers and came before Shuriken Sentai Ninninger) while sporting a new head.
- Cosmo Royale is the third Power Rangers villain adapted from a different Sentai series than the one his respective season was based off of. The first was Furio from Power Rangers Lost Galaxy, whose costume came from Denji Sentai Megaranger, not Seijuu Sentai Gingaman. The second was Master Org, who's costume came from Gosei Sentai Dairanger, not Hyakujuu Sentai Gaoranger.
- As opposed to Ninninger where as Madame Odius' counterpart was the one who grew the monsters and summon the Gashadokuro, he is the one growing the monsters and summoning the giant Skullgators with a special machine.
- His facial expression is able to change based on his mood. He normally looks happy, but has an angry expression when Spinferno tried to upstage him in "Live and Learn", along with a shocked expression when learning that Tangleweb had eaten a Kudabot in "Drive to Survive." The same episode also shows that he is able to spin his head in order to turn his face back to normal. Because of this, he shares some similarity to the Mayor of Halloween Town from The Nightmare Before Christmas

- Kyuemon Shingetsu Kibaoni - Super Sentai counterpart in Ninninger. See comparison page. (as a role for growing the monsters and summoning the giant Skullgators)
