Mystery Comet Typhoon (怪彗星ツイフォン Kai Susei Tsuifon) is the 25th episode of Ultraman. On the DVD release it is only called The Dreaded Comet Tsuiphon/The Dreaded Comet Twenty-Four.


When the giant comet Cyphon was headed towards earth the SSSP division in Paris discovered that it's cosmic rays might set off unprotected Hydrogen bombs. Japan's SSSP sent members Shin Hayata, Daisuke Arashi, and Mitsuhiro Ide to search for six missing hydrogen bombs in the Alps. Shortly after the men arrived in the Alps, Cyphon had already passed over the Earth, but it's presence disturbed the kaiju Gigass, then later Dorako. Still in search of the missing bombs the SSSP found another generation of Red King (generation II), who had  the missing hydrogen bombs on his neck.

Red King then found the two previous kaiju locked in combat and decided to join. Both he and Gigass ganged up against Dorako and beat the kaiju mercilessly. Red King viciously tore Dorako's wings off, and Dorako died of it's injuries soon afterward. Gigas was driven off by Red King and fell victim to the Extreme Drought Bomb deployed by the SSSP. All three monsters apparently precipitated out of a fragment of comet debris, or were awakened by the comet's radiation; it is not entirely clear, but the comet somehow triggered their appearance. Apparently Red King now presented an extra danger, as it had swallowed six long-lost hydrogen bombs. Ultraman appears and ultimately paralyzed Red King and raised it off the ground with the Ultra Air Catch. He then used two of his Ultra Slashes to slice Red King into thirds. Ultraman took the head and neck portion and flew away into space with it to allow the H-bombs to detonate harmlessly.
