Subtitle: Poison Flame Monster (毒炎怪獣 Doku En Kaijū)[1]


Ultraman Taiga

Segmeger is one of many planet-invading monsters used by the Alien Seger used to conquer planets with suitable conditions for their race. One Seger named Aoi decided to attack Earth with her own Segmeger.

Segmeger first fought Ultraman Taiga, poisoning his left arm with the Seger Flame, which transferred the damage over to Hiroyuki Kudo as well. Taiga destroyed it using the Strium Blaster after a brief fight, but Hiroyuki had to get a cast over his arm afterward. Alien Damara then came into the EGIS base to warn them that his planet was destroyed by Segmeger, and that it would continue to return as long as its summoner was still around.

Aoi summoned Segmeger again after she thought that Pirika Asahikawa, whom she met recently and became friends with for a short time, was spying on her. Taiga, Fuma, and Titas fought against Segmeger but their efforts were insufficient even when Taiga blasted it with the Mons Beam Ray. Ultraman Fuma also had a difficult time with Segmeger and switched with Ultraman Titas, who chopped its tail off. Titas was sprayed with Segmeger's poison blood that came gushing out of its wound, disorienting him, which allowed Segmeger to knock him down. Pirika managed to convince Aoi to do the right thing, so she used her crystal ball to give up her life force, which then entered Titas and healed him. Titas then pounded Segmeger and finished it off with the Electro Buster, turning it into a ring that Hiroyuki collected. The Future You Decide


  • Designer: Daisuke Inomoto (Completed), Kiyotaka Taguchi (Initial)
  • Suit Actor: Hiroyuki Arai
  • Although the effects of Segmeger's attacks and poison were carried over to Hiroyuki, they do not seem to be shared between the Tri-Squad members for some reason.
  • Its name is possibly derived from Egyptian goddesses name, Sekhmet and Meretseger.
  • Due to the origin of its name, Segmeger's design comes from snakes and lions and is meant to look like a snake from the side and lion from the front. 
  • According to Kiyotaka Taguchi who made Segemeger's initial design before Daisuke Inomoto modified it, Segmeger in the past likely looked different to its appearance in Taiga, believing it had deteriorated from its original beauty from overuse in planetary conquest. It could be presumed the malicious intent of its controller changed it to be more evil.
