Godzilla: Rulers of Earthland Wiki

Gigan is a Cybernetic Space Dinosaur Kaiju that was created by the M-Space Hunter Nebula Aliens/Nebulans. After the Nebulans' extinction in The Thousand Year War, Gigan encountered King Ghidorah and the two went to Terra where they countered Godzilla in 2002. He would become one of Godzilla's major enemies.


In his original form that was constructed by the M-Space Hunter Nebular Aliens, Gigan's skin was a dark green colour and he possessed golden scales over several parts of his body. On his back are three, large yellow fin-like spines on his back. Spikes run down Gigan's tail. His metal, toothy beak is silver with tusks at the side of it. Instead of eyes, Gigan has a red cybernetic visor. Gigan also has a spike/horn on top of his head with smaller spikes running down the neck and end when they meet the back fins. Instead of hands, Gigan instead has large steel hooks and on his feet he smaller ones for toes. In abdominal region, Gigan has a buzz saw.

He was soon given an upgrade by the Cryogs when under their control. Gigan is given a more cybernetic body and now dark blue skin. His body is now also thinner and more streamline, he also has wire like structures on his body. The fin-spines are now red in color. The spikes on his tail also have metal plating. On the tip of his tail is a metal claw for grappling. The hooks are now replaced with more scythe-like blades with grappling hooks, these hooks are visible as smaller hooks on each side of scythes.

On his knees are metal plates and also have spikes on them. After being damaged from his battle with SpaceGodzilla, Gigan has his scythes replaced with double-pronged chainsaws. The spike on his head and the tusks at each side of his mouth are now serrated.


Gigan is a Kaiju that rarely seems to act on his own accord often, usually just following orders of whoever is commanding him at the moment without much question. In a way, he could be thought as a mercenary for hire. The few times he is seen acting on his own choice, the cyborg is an odd book to read. He certainly doesn't bat an eye visor at causing mass destruction, but does it more out of being told to and simply not caring to oppose instead to relishing devastation. In battle, Gigan is a ferocious duelist, but not the extent he will not know when it is time to retreat from a lost battle, such as when he retreated after being brutally beaten and losing an arm to Godzilla. He also has a bad tendency to underestimate new opponents. 


It isn't entirely sure when or where Gigan was first found and rebuilt into a cyborg, but what is known is that he was originally an alien dinosaur that was discovered by the Nebulans and rebuilt into a cyborg to serve under them. During the Thousand Year War, he and his younger brother Megalon served as their secret weapons when the Nebulans and the Xilians formed an alliance against the Kilaaks, Simians and Millennians. When his masters were destroyed at the end of the war, Gigan wandered the galaxy aimlessly until he crossed paths with King Ghidorah before both were lured to Terra by Dr. Deverichs Psionic Transmitter.

At some point, the two were confronted by Mothra and Battra, but Gigan and King Ghidorah were able to defeat them. They where also confronted by Anguirus and defeated him as well.

Post-Trilopod War Arc

While Gigan himself doesn't appear, he appears in Godzilla's memories as the Shobijin show the core members of Fairy Tail Fairy Tail after the Earth Defenders were transported to Earth Land. As the Fairy Tail mages witness Godzilla's memories, they see Gigan in his battles against Godzilla, Kiryu, Anguirus, Rodan and Jet Jaguar.


Giganium Laser: Gigan's primarily energy based attack, Gigan can fire a red laser of energy from his eye visor. This weapon can cause great damage against opponents.

Buzz Saw: Gigan has a buzzsaw built into his abdominal area. This allows him to slash deep wounds into an opponents hide, being able to cut at Godzilla's skin. A tactic Gigan uses a lot is to use his powers of flight along with his buzzsaw in hit and run attacks, slashing his opponent as he races by them.

Arm Appendages: Gigan has always had some form of arm based weapon given. In his case he has had three different types.

  • Hooks: His original cybernetic arm appendages before being upgraded, Gigan used his hooks to slash deep into an opponents hide and skin, as well as to latch on to opponents.
  • Scythes/Grappling Hooks: When he was under the control of the Cryogs, Gigan is upgraded and give scythe like blades which work simalry to his previous hook. However, these blades were also been given grappling hooks that can shoot out and bind opponents so Gigan can swing, drag or pin his opponents
  • Chainsaws: Gigan's current hand weapons, soon after his battle with SpaceGodzilla, Gigan is upgrades to having duel-chainsaws. The chainsaws are powerful energy to shred through the hull of a Cryog Ship and cripple it.

Razor Disks: As part of his Cryog upgrade, Gigan is given he ability to fire guided razor discs from two hidden slots in his upper torso. These disc have a boomerang affect as they come back if they miss their target. Some times this can be a risky tactic as an enemies could potentially use the disks against Gigan's advantage such as when Godzilla used them to free himself from Gigan's Grappling Hooks.

Flight: Gigan is capable of flying at high speeds while in Earth's atmosphere. In space, Gigan can fly even faster, so fast that he can sometimes look like a flaming purple comet from a distance.

Tail Claw: As part of his upgrade, Gigan is given a grasping claw at the end of his tail. With this claw can grab enemies or even jab them in the manor of a scorpion.

Immense Strength: Having been heavily modified with Nebulan technology during the Thousand Year War, Gigan has been shown to posses incredible strength in combat. During his first invasion on Terra, he and King Ghidorah were able to defeat both Mothra and Battra as well and Anguirus before confronting both Godzilla and Kiryu on equal footing. He was also shown to be strong enough to drag Godzilla across the city of Las Vegas by his tow cables alone after being further modified by the Cryogs. In his last modified form, he was able to use his chainsaws to carve through an entire fleet of heavily armored Cryog warships with ease and fight on par with Jet Jaguar.

Immense Durability: Gigan's bionic enhancements have allowed him to gain stronger defenses, being able to take blows that would normally be fatal for any other kaiju. He's survived direct blows from Godzilla's Atomic Breath and even took a direct blow to the head by Anguirus in his spike ball form, which didn't kill him, but instead put him in a deep coma for only two years. He's even managed to survive having his arm ripped off twice (once by Godzilla and the other by SpaceGodzilla) and being curb stomped by both Godzilla and Jet Jaguar at once.

Enhanced Speed: Not only has Gigan gained greater strength and durability from his enhancements, but also speed as well. He's fast enough to fly across the cold vacuum of space at high speed and fight on par with Rodan, who is said to be one of the fastest flying Kaiju on Terra. Gigan is also as fast on land as he is in the air, being able to attack foes with precise and lightning fast strikes that can render them immobile in mere minutes. He was even fast enough to destroy an entire fleet of Cryog warships in space without being struck himself.

Enhanced Endurance: Being a cyborg, Gigan doesn't require sleep and is unable to feel exhaustion, allowing to fight for hours without feeling fatigued. Unfortunately, he does require a rest period between missions in order to ensure his systems are kept in peak condition and to avoid them from overheating as well as for occasional repairs should he be damaged in combat.

Bionic Enhancements: Throughout his life, Gigan has gone through numerous bionic enhancements, granting him enhanced strength, speed and durability. This also gives him access to a wide array of both ranged and melee weapons, including lasers, cables, razor disks and so on.

Expert Hand-to-Hand Combatant: A highly trained expert in the art of battle and warfare, Gigan has fought against some of the strongest kaiju in his time, including Jet Jaguar, who is another expert in close combat.
