Gigan

Gigan (ガイガン, 'Gaigan') is a Kaiju from the Godzilla series, introduced in the 1972 film Godzilla vs. Gigan. Gigan is a monster sporting a buzzsaw weapon in his frontal abdominal region and large steel hooks for hands and feet. Gigan is sometimes considered Godzilla's most brutal and violent opponent, and has a large fan following (including Godzilla: Final Wars director Ryuhei Kitamura) despite the generally perceived low quality of its first two films. His new designs for the Millenium series was praised by many and ranked among fans as the best improvements to any monster. He is one of the most popular Godzilla villains in the films. In the Showa series, he is an alien beast, while in the Millenium series, he is portrayed as an evil entity and one of Mothra's arch nemesis.

Bio
GIGAN is renowned throughout the galaxy as the pinnacle of monster elimination technology. If his younger brother MEGALON is the demolisher, GIGAN is the assassin, and he wears the title with pride. There's no record of exactly when Gigan was built, other than that of the insectoid aliens of Nebula Space Hunter M, and even their own records are spotty at best. While the Nebulans do indeed control Gigan and send him on whatever mission of bloodshed they so deem, there is no evidence to support that they themselves created the cyborg. Gigan's inner workings and horrifically beautiful mesh of synthetic allows, circuitry and organic flesh may be just too far beyond the grasp of the somewhat technologically challenged sentient cockroaches. It has been theorized even that Gigan was a creation of a race that preceded the Nebulans, and they simply "inherited" it (if their story of their home planet is to be believed). While the gigantic cyborg does indeed answer to the Nebulans, he does seem to have a conciousness and sentience of his own...it would almost seem as though he tolerates the Nebulans rather than being subservient to them. This is indicated by the cockroaches' tendency to act as though they control him, yet almost bend their plans around Gigan's actions. Godzilla and Gigan share a relationship based on rivalry rather than aggression, and while the two are perfectly willing to beat each other to death, there's an air of respect that each has for the other. Megalon isn't as smart or as efficient as his older sibling, yet Gigan seems to maintain a cool set of circuits when dealing with the simple yet effective hailstorm of destruction that Megalon rains down on whatever pitiable civilization incurs the beasts' wrath.

Though chased from Earth by Godzilla and Anguirus, Gigan returned in during Operation: Final War, upgraded and ready to carry out a new set of wicked plans...
