Ultraman Orb Darkness (ウルトラマンオーブダークネス Urutoraman Ōbu Dākunesu) is a dark clone of Ultraman Orb that first appears in Ultra Galaxy Fight: New Generation Heroes. He is presented as a member of the League of Darkness.
Ultra Galaxy Fight: New Generation Heroes
Orb Darkness was created by Ultra Dark-Killer using the energy stolen from Ultraman Orb by X Darkness and Geed Darkness. However, its appearance is incomplete as X Darkness and Geed Darkness were interrupted by Ultraman Victory. Nevertheless it is already as powerful as Orb.
Upon creation, Orb Darkness was blasted with Tregear's lightning as a reminder to Dark-Killer of his original goal. When the New Generation Heroes storm the Planet Tenebris, Orb Darkness fought against its template and managed to shrug off Orb Origin, Spacium Zeperion and Burnmite. He was killed after Orb changes to Emerium Slugger and fires he ES Specium, followed by the Hyper Ultra Knock Tactics. In a desperate attempt to gain advantage over the New Generation Heroes, Dark-Killer recreated Orb Darkness and the other three Darkness warriors, only to consume them and grow even larger.
