"The tragedy will reappear, just like before..."

―Kokakucho to Mayomi Shinjo in her dream, "Bird of the Phantom Dream"

Kokakucho (姑獲鳥コカクチョウ Kokakuchō) is a monster from Ultraman Dyna.

Subtitle: Misfortune Monster (凶獣 Kyō-jū)


Ultraman Dyna

Kokakucho was actually a sentient cloud of plasma which took the form of its spiritual namesake and first appeared in the dream of Mayumi, reminding her of the death of her boyfriend at the hands of Gazort. The monster made herself known in the center of the Chinese Mainland, heading straight towards Tokyo while destroying Chinese power plants. As Kokakucho arrived at the open air of Tokyo and was attacked by the Super GUTS member Shin Asuka, with no avail as Kokakucho is resistant to lasers, being intangible to the beams. However, Ryo and Nakajima appeared with a new weapon: the Anti Plasma Bomb, which they fired upon and forced her to return into her cloud form and disappear. Kokakucho reappeared where the second Gazort had struck years earlier and began to drain the long lost plasma energy, which was still in the air. Super GUTS was unable to do anything as the large amount of plasma energy had fueled Kokakucho enough to resist all of their attacks, even keeping Dyna at bay with clever use of long ranged attacks until a thick mist fell over. Mayumi, who happened to be there, saw her deceased boyfriend Takuma reappear again in front of her, distracting Kokakucho as he did to Gazort, giving Dyna the time he needed to change into Miracle Type. As the mist faded, Kokakucho unleashed a thunder cloud as Dyna, who unexpectedly absorbed the energy and recharge himself to banish her to an alternate dimension via the Revolium Wave Attack Version. Bird of the Phantom Dream

Sometime later, the image of Kokakucho was shown among the Phantom Monster Army before the illusion unveil itself as Moravia. The Power of Thinking of You


  • Kokakuchu's episode is a tribute to Gazort II's episode. Initially, the plan was to have Gazort return to this series but the departure of Clitters from Tiga made it impossible for them to reappear.
  • Kokakucho's origin of myth is variable on certain countries:
    • In China, she is known as Gu Huo Niao (姑獲鳥), a bird in Chinese lore that kidnaps girls and raises them as their own.
    • In Japan, the kokakucho is a yōkai called Ubume, a Japanese spirit of a woman who died delivering a child without providing care for her baby.
