Black Pigeon (ブラックピジョン Burakku Pijen) was a Terrible-Monster created by Yapool. He appeared in episode 18 of Ultraman Ace. Although appeared to be a transformation, in truth, Yapool performed a brain transplant of an Earth pigeon into a space monster, wanting to use its homing instinct.

Ultraman Ace

Using a small boy's pigeon named Kojiro (小次郎 Kojirō) as their personal test subject, Yapool transformed the harmless Kojiro into a ferocious Terrible-Monster. The avian monster was unleashed on Japan but was deterred by TAC. Black Pigeon immediately went on the offensive, rampaging through a construction site before smashing several apartment buildings to pieces. Yapool, however, was furious, as his monster was attacking without him giving it orders to do so, and so he soon recalled the monster back to his dimension.

Some time later, the boy, who knew Black Pigeon was Kojiro, attempted to call him to a harbor, and Black Pigeon appeared again. The Terrible-Monster spat out jets of flame and unleashed hurricane-force winds by flapping his wings. As TAC was about to be burned by Black Pigeon's fire, Hokuto and Minami called on Ultraman Ace to fight the Terrible-Monster. The Terrible-Monster and the hero clashed, and it was clear that Black Pigeon had the upper hand, whacking Ace around with his chest spike and spewing his regurgitation fluid at him, then following up with his fire.

As the fight continued, Ace's energy began to wane as Black Pigeon used every extent of his abilities on the hero. After Black Pigeon discarded his chest spike, Ace used the opportunity to fire his Metalium Ray at Black Pigeon, seemingly defeating the monster, but this was not the case. After quivering for a moment, Black Pigeon shot the energy back in the form of a purple beam which struck Ace, leaving the hero in bouts of pain! TAC could only look on in horror as Black Pigeon closed in and began relentlessly beating Ace, who was so badly injured by the assault that he was left briefly unable to stand after climbing out of the harbor.

Immediately knowing what to do, the boy used his pigeon whistle to call Black Pigeon again, who stood to attention. Realising this was perhaps his final chance, Ace got up, and while Black Pigeon was distracted by the whistle, shot him in the back with his Diamond Beam. Black Pigeon turned around to face Ace, but then fell limp, and his eyes closed for the final time as he breathed his last. Afterwards, Black Pigeon reverted back to Kojiro, but remained dead. TAC then held a funeral for the bird, while the boy blew the whistle for the final time to honour the fallen creature.Lend Me the Pigeon


  • Depending on the interpretation, some source stated that Yapool performs a brain transplant of Kojiro's to a space monster to give it a pigeon's homing capability.
  • In an alternate story by Mamoru Uchiyama, instead of dying, Black Pigeon was revived as an ordinary pigeon after being defeated by Ace, essentially resurrecting Kojiro.
  • Black Pigeon is a heavily modified Cowra suit.
  • Black Pigeon's roar appears to be heavily altered from Varan's but reversed and segmented.


  • Height: 57 m
  • Weight: 43,000 t
  • Origin: Yapool's Dimension
  • Weakness: Due to Black Pigeon's creation from Kojiro, a trained homing pigeon, Black Pigeon will stop whatever he is doing and stand to attention whenever the pigeon whistle that was used to call him is used. This leaves Black Pigeon vulnerable for a brief period of time.
Powers and Weapons
  • Extreme Strength: Even when flying, Black Pigeon can lift heavy objects and move without it visibly slowing him down.
  • Flames: Black Pigeon can emit flames from his beak.
  • Beam Reflect: Black Pigeon can reflect beams back at their source.
  • Regurgitation: Black Pigeon can regurgitate white sticky fluid (which is probably Crop milk or stomach acid) at its opponent, which paralyses them for short periods of time. This fluid seems to be dissipated by fire.
  • Missile Thorn (ミサイルトゲ Misairu Toge): Black Pigeon has a large spike in his chest which he can use as a bludgeoning weapon, and he can also fire it from his body to attack opponents or cause destruction.
  • Hurricane Winds: Black Pigeon can create hurricane force winds from his wings.
  • Flight: Black Pigeon can fly at low speeds.
