Guiron(monster)

Guiron is a Kaiju that appeared in the fifth original Gamera movie, Gamera vs. Guiron, (Known statewise as "Attack of the Monsters"). Due to the lack of distinction in Japanese between the "l" and "r" sounds, Guiron is actually named after the guillotine.

Guiron is an alien monster that normally traverses on all fours, but can also assume a bipedal stance. It is an unusual looking creature, with tough gray skin, a small mouth, sleepy looking eyes and a low, groaning bellow. The most unusual feature of this beast's anatomy, however, is the gigantic blade that it sports on its head, which is nearly as long as its body.

Guiron is mostly a melee oriented kaiju, attacking opponents with its blade. Indeed, this blade is so sharp that it can even cut through Gamera's shell. It also has a reflective surface that can send an enemy kaiju's beam attacks back at its opponent. In addition, there is a circular indent on either side of the blade. Housed within are shuriken that it can apparently launch with some kind of psychokinesis.

Guiron acted as the guard dog of two brain-eating space women, the last of a dead civilization on the planet Terra. The aliens guided him with a mind control device. Guiron proved his combat prowess by effortlessly defeating a Gyaos, reflecting its sonic cutter beam and literally slicing it to pieces with his blade. Guiron later fought Gamera, and nearly killed him as well. After a long fight, Gamera eventually managed to defeat the knife headed beast by flipping him upside down - his blade stuck in the earth - then igniting a missile that had gotten stuck in his circular indents, blowing his head off and killing him.
