Spirass (スパイラス?) is a SupairasuMutian kaiju created by Toho that first appeared in episode 4 of the 1996 tokusatsu kaiju series, Seven Star Fighting God Guyferd titled Escape from the Genetic Laboratory.
Spirass is first seen using a web attack to steal a bus full of children to use as bait to lure Guyferd to a Crown Genetics facility. She is seen again at the end of the episode after being summoned by Megumi Shion to fight Gou Kazama, at first underestimating the female Mutian and told her not to get hurt. After the childrens escaped the facility, Spirass was ordered to kill Guyferd as his dead body is good enough for experimentation. However, she eventually meets her end as Guyferd hit her in the face with Jiraishin (Landmine shock) technique. Spirass is the first Mutian to have no lines of dialogue in her debut episode.
- Spiral Beam is a purple ki attack that explodes on contact, even against other ki attacks.
