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


When the giant comet Tsuifon was headed towards Earth, the SSSP division in Paris discovered that its 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, Tsuifon had already passed over the Earth, but its presence disturbed the kaiju Guigass, 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 Guigass ganged up against Dorako and beat the kaiju mercilessly. Red King viciously tore Dorako's wings off, and Dorako died of its injuries soon afterward. Guigass 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.
