Alien Waiell (ワイアール星人 Waiāru Seijin Waiell Star-people) were aliens from the planet Waiell who feed on human blood. He is also known as Alien Wyaan.
Subtitle: Organisms X (生物X Seibutsu X)
An alien plant covered with countless thorns, Waiell uses two extraterrestrial Tilsonite 808 rocks to disguise himself as Ishiguro, a crew member of Space Station V3 who has just returned to Earth. Under the cover of night, Waiell reverts to his true form and begins attacking humans by sending blood-sucking tentacles down the streets. In turn, the victims become Waiell-type monsters themselves, and spread the vampire-like epidemic across the city.
When his Tilsonite 808 rocks are destroyed (revealing that they contain alien machinery and the real Ishiguro within), Waiell's cover is blown, which then forces him to go through a gruesome transformation while on a train in the middle of a tunnel. He then takes on giant size and battles Ultraseven until he's cut completely in half by his Eye Slugger. Ultraseven then destroyed the halves with his Emerium Ray.
