Devising a cunning plan, Chaos Ultraman flies to Kapuya Island, and tries to infect the monster inhabitants but fails due to the island's power field. Reappearing, Chaos Ultraman 'attacks his Wheel of Darkness and turns it into Chaos Neldorand.

With Musashi captured, Chaos Header is able to Strike again when Neldor and emerge from the ground. Instead of destroying the giant, the entity itself transformed into the Chaos Ultraman and overpowered it, forcing it to return to Musashi and capture him. When Musashi was forced out, the creature tried to assimilate Musashi by forcing him to transform into Cosmos as desired. The ball moved over him and chased after Musashi. One day, EYES handled Chaos Organisms in Treasure Base. This heinous evil warrior is able to match the movements of the guards, able to fight back unlike the other Chaos agents and he outlasts the guards, surviving as Ultraman Cosmos runs out of energy.

Almost forgot Zoffy, for being a ruthless hatchet-man.ДЄlmost need a poll going to get to the bottom of this.Chaos Ultraman / Chaos Ultraman Calamity is a dark clone of Ultraman Cosmos summoned by Chaos Organisms.

Does he count as a 'hero' ultra though? Technically, that would just be Tiga.

Dark Tiga makes sense, especially if I had considered early form Belial, whom Tiga is practically the inversion of.

Doesn't totally fit the 'brutal' bill though. I think if you were to take the original question for its yin/yang aspect, this one is just the most direct and obvious answer.

Solid points for Justice, in that they were always intended to be the dark mirror of Cosmos.

he got Minami killed within 5 min of meeting her.

Ace because of his 'chop their heads off/chop them in half/totally dismember them and ask questions later' policy.

the Shin/Shodai Ultraman for his 'if it moves, SPACIUM IT' attitude (and just unnecessary treatment of Jirass) which I think makes him a solid contender.

So far it sounds like people are leaning toward: Trying to get a consensus here for a potential future post. Tiga: Did also a bunch of evil shit back in the days. You probably need to be a bit morally ambiguous to get the rank of the mantle.ДЄn interesting scenario would be if Father of Ultra promotes Taro to his position while skipping Zoffy.Дestroyed an entire inhabited Planet with the ultra key HeвЂ™s students still cared for him years 26 years later. He had three jobs at once at the beginning of the show and actually cared for all of them. I donвЂ™t think he ever did anything too crazy. Mebius: HeвЂ™s probably the nicest of the brothers.

Father of Ultra didnвЂ™t even wanted to put him in the space garrison at first because he thought that he is fucked up in the head for life. Hikari: HeвЂ™s also got some serious traumatic moments behind him. Astra: HeвЂ™s doesnвЂ™t talk much because he was tortured by alien magma for years and probably suffers from pdst. Even kicking Ultraman aces head off with the leo kick. And he even still cared for Tregear even through he was a huge piece of shit friend that killed his son. He even saved a view kaijus instead of killing them. Taro, well he is probably the nicest of the ultra 6 brothers. Ace: Chojus donвЂ™t feel pain! (Except when they scream in pain) Besides that heвЂ™s a good guy. But i donвЂ™t expect him to go evil, since heвЂ™s against mass murder as he expressed multiple times through the show. Seven? Well he would kill anyone if the fate of earth is at stake. He nearly killed Leo and Astra without giving too many shits. And Zoffy always seems like a guy who would do anything what someone orders him to do. I donвЂ™t think all alien Varducks where evil. And Shinman destroyed the alien Varduck homeplanet. From the point of an alien baltans view, Ultraman is pretty damn evil.
