Was once a human warlord before transforming into an Oni.
Has always been an alien and is the heavyweight champion of the intergalactic game show, Galaxy Warriors.
He has been sealed away 444 years ago and spent throughout the series as a disembodied voice whenever a corrupt shurikan creates a Yokai, before being revived with a full amount of fear.
He first appeared on Earth 10 years ago to obtain the Ninja Nexus Prism for it's ultimate power. He's mainly active with making schemes to obtain the Power Stars from the Power Rangers, by sending down each warrior contestant at a time.
Did not obtain any of the Ninningers' OtomoNin Stars in any other way.
Had obtained the Zord Stars because of Victor and Monty's Magnet attracting them.
Was destroyed by the Ninninger in the finale. With his end, after the destruction of his generals, his clan is no longer a threat.
Was weakened by Madame Odius, and then destroyed by the Ninja Steel Rangers in the first season finale, making Odius the one responsible for his death. However, Odius and Cosmo survive and the Super season follows, with Odius in charge of Galaxy Warriors and the later-appearing generals working for/with her.
Destroyed by the Ninja Star Morph Final Attack (which was his Sentai death edited into a quarry to match American footage around it). Never encountered the Ninja Blaze Megazord as it had not been created yet.
Died claiming that he would return one day and told the Ninningers to be ready,
Died moaning that this was impossible as he was the champion of Galaxy Warriors.
