Ultra Dark-Killer

Ultra Dark Killer (ウルトラダークキラー), or simply Dark Killer, is the primary villain in the pachinko game, Ultraman Taro: Revenge of the Dark. He also appears in various stage shows and events and most recently, Ultraman Festival 2017. In 2019, he makes his first on-screen appearance in the Ultra Galaxy Fight: New Generation Heroes spin-off.

Ultraman Taro: Revenge of the Dark
Dark Killer is said to have been born from the grudge of various monsters and aliens destroyed by the Ultra Brothers much like Grand King and Tyrant. However, unlike those two monsters, Dark Killer is capable of reasoning and conversation.

He would harass Taro, by reviving several monsters, to weakening him, and covering the Earth with the 'Killer Plasma' effect before facing him directly. Although initially overpowering him easily, he was defeated when the Ultra Brothers, from Zoffy to Ace, appeared and merged with Taro to grant him his Super Taro form. Defeated by an Ultra Dynamite, Killer's eyes turn blue as he encounter a new emotion, Taro self-sacrifice, with his Ultra Dynamite.

Despite his defeat, Dark Killer would later return, revived by his hatred for Taro. At this time he learned to use the Killer Plasma attack separate from his body and create the Ultra Dark Killer Brothers, dark doppelgangers of the Ultra Brothers that assisted Taro in their last fight. He would then attack Ultraman Mebius and the other Ultra Brothers but would be driven off.

Later he would appear and attack Ultraman Zero, but was defeated.

Ultra Galaxy Fight: New Generation Heroes
Ultra Dark Killer has revived and teams up with Dark Lugiel and Etelgar to fight against the New Generation Heroes. He steals the light of Ultraman X, Ultraman Orb and Ultraman Geed to create his minions Ultraman X Darkness, Ultraman Orb Darkness and Ultraman Geed Darkness.
