Gigan is truly a strange monster, sporting a circular saw weapon located in his frontal abdominal region, large steel hooks for hands with smaller ones for toes, spikes running down his tail, three, large fin-like spines on his back and a red cybernetic visor for an eye.
He also bears various avian characteristics, such as a 'crest' made of metal spines and a metal beak. In the Showa series, Gigan's skin was a dark green color and he possessed golden scales over several parts of his body. In Godzilla: Final Wars, Gigan's appearance was changed to make him appear more cybernetic. In this film, Gigan's skin is now a dark blue, his body is much thinner and more streamlined, and there are wire-like structures running across his body.
When Gigan is revived as Modified Gigan, his hook hands are replaced with double-pronged chainsaws. Gigan's new design for the Millennium series was praised by many and ranked among fans as one of the best improvements to any monster.
Gigan is sometimes considered Godzilla's most brutal and violent opponent, and has a significant fan following (including Godzilla: Final Wars director Ryuhei Kitamura) despite the generally perceived low quality of his first two films. Gigan is shown to be very vicious and sadistic in combat, preferring to shred his opponents up close with his hook hands and buzzsaw.
However, at least in the Showa series, Gigan appears to be a bit of a coward, retreating and leaving his ally at the mercy of his enemies as soon as the tide of battle turns against him. In Final Wars, Gigan is shown to be somewhat incompetent, having his head easily blown off by Godzilla's atomic breath and later slicing his own head off with two razor discs intended for Mothra.
In Godzilla Island, Gigan actually becomes an ally of Godzilla after being defeated by him, and assists him and the other residents of Godzilla Island in fighting off invading monsters. This is the first and only time Gigan has been depicted in a benevolent light.
In Godzilla: Final Wars, Gigan is an ancient cybernetic monster that was sent to Earth by the Xiliens thousands of years ago, where he was defeated by Mothra and subsequently mummified. In the year 20XX, Gigan's mummified corpse was discovered by the Earth Defense Force, and the monster was later reactivated by X during the Xiliens' invasion.
HistoryGodzilla vs. Gigan where he was controlled by the M Space Hunter Nebula Aliens. He was sent to earth to destroy it with King Ghidorah. They attacked a city, but they were interrupted by Godzilla and Anguirus. They battled at the World Children's Land, and they nearly killed the two monsters. After the destruction of the Godzilla Tower, Gigan and King Ghidorah are released from their mind control, and the two Earth monsters drove them back into space.
Godzilla vs. Megalon, as he was called by the Seatopians to help them conquer Earth. He arrived to help Megalon battle Godzilla, and they nearly killed him. Jet Jaguar attacked Gigan, but he was also defeated. The two monsters regained their strength, and they fought Gigan and Megalon off again. Gigan retreated back to space, and Megalon returned to Seatopia.
Garogas' Terror Beasts in Zone Fighter. It is revealed that after he was driven into space once more by the combined efforts of Godzilla and Jet Jaguar, he was captured by the Garogas. During his last battle, his cybernetics had been heavily damaged, so the Garogas repaired him. Most notably, Gigan had trouble slowing down when in flight, and had to deploy a set of parachutes like a spacecraft.
However, the Garogas outfitted Gigan's claws with a special ability that made objects explode when he hit them with the weapons. Gigan was sent to Earth, where he battled Zone Fighter, and nearly overpowered him. However, Godzilla, who had became close friends with the Sakimori Family, and remembering Gigan, took him on in a second rematch, beating down Gigan and forcing him to retreat yet again. However, the Garogan control over Gigan remained, and they sent him into battle once again.
However, the damage Gigan sustained while fighting Godzilla hadn't been repaired, and Gigan was beaten badly by Zone. After a short battle, Zone Fighter used his Meteor Missile Might on Gigan, and the alien monster fell to the ground whilst gushing black smoke, and exploded, finally ending Gigan's life for good.
Story 5In Godzilla Island episodes 31-40, when Zaguresu gets upset on the reports of her failures while reading a newspaper, a M Space Hunter Nebula Alien crawls into view and says to Zaguresu that it's here to help her conquer Godzilla Island, so the M Space Hunter Nebula Alien introduces Gigan to Zaguresu, which impressed her, and Gigan heads down to earth.
When Godzilla sees Gigan, Gigan levels off and starts a scan on Godzilla, and succeeds in doing so, Gigan then prepares to leave as Torema arrives on the scene, but Gigan flies over Torema's ship, and Zaguresu was annoyed when Gigan didn't even bother to fight. Gigan then fires an arrow with a note tied onto it to Godzilla Island from space, it turns out that the note said that Gigan has challenged Godzilla to a battle at sunrise, so Godzilla heads out to battle, only to be stopped by King Caesar, who then warns Godzilla that Gigan is too strong and needs to prepare before the battle, but Godzilla roars in defiance, then Torema begs Godzilla to listen, but Godzilla marches past King Caesar refusing to listen.
Godzilla finally reaches the battle site and finds Gigan waiting. The two monsters then begin to wait through the night before attacking, when the sun rises, Gigan reflects the sunlight off its claw, blinding Godzilla by the reflection. Gigan sees its opportunity and starts to charge at Godzilla, only for Godzilla to regain his sight, causing Gigan to halt its charge, and leap back to where it started attacking from.
Zaguresu starts getting frustrated that Gigan isn't fighting Godzilla, so she calls out Battra, only for Gigan to fire its Cluster Beam at Battra. The M Space Hunter Nebula Alien alien then assures Zaguresu that Gigan can defeat Godzilla on its own.
Godzilla and Gigan continue to face off as everyone waits in anticipation. When a landslide falls between Godzilla and Gigan, the two monsters begin to charge, but unfortunately, Godzilla goes down, much to everyone's surprise. Gigan then approaches the fallen Godzilla when Mothra suddenly appears, and attacks Gigan with her scales, then Rodan appears, picks up Godzilla, and flies away with Godzilla as Mothra follows.
Gigan watches, but turns away as Godzilla escapes. At King Caesar's healing spa, Godzilla admits to King Caesar that he wasn't ready to face Gigan and should've listened in the first place. King Caesar then tells Godzilla that he needed to use powers he's never used to defeat Gigan, and can train Godzilla how to use those powers. Gigan then appears, much to Godzilla and King Caesar's surprise.
However, it did not attack, but instead, enjoys the hot spa, as Godzilla and King Caesar watch. Gigan then rises out of the spa and challenges Godzilla at sunrise for the final battle, and Godzilla accepts Gigan's challenge. Before their final battle, Godzilla is seen meditating as Rodan flies by, King Caesar approaches as Godzilla continues to meditate. King Caesar taps into Godzilla's inner power, then walks away.
The next day, Godzilla has reached the battle site, and Gigan flies into position while King Caesar's gathered all the monsters, and warns them not to interfere in Godzilla's battle with Gigan. The monsters disapprove, and King Caesar roars in defiance, causing the monsters to step back.
Godzilla then closes his eyes, much to Gigan's confusion, and a green aura surrounds Godzilla, causing Gigan to step back. The green aura disappears and Godzilla opens his eyes. Godzilla suddenly fires his Radioactive Heat Ray aimlessly into the sky. Gigan sees its opportunity and charges Godzilla. In midair, the ray does a 180 and hits Gigan from behind, and everyone is shocked as to what has happened. Gigan looks back to see who attacked it, and Godzilla sees his opportunity and charges Gigan. As Gigan turns back around, Godzilla leaps in the air and strikes with a spinning tail attack, knocking Gigan down to the ground.
The fallen Gigan looks up at Godzilla as the King of the Monsters looks back. Gigan soon falls unconscious, and all the monsters come to congratulate Godzilla, even Torema is happy that Godzilla was able to defeat Gigan. but Zaguresu swats the M Space Hunter Nebula Alien alien with her newspaper because the plan's failed.
Gigan reappears in episodes 117-118 when Godzilla is getting a beat down from Destoroyah and Megalon. At first it would seem like Gigan is helping the two monsters against Godzilla, but as it turns out, Gigan is actually helping Godzilla when Gigan knocks down Megalon. Destoroyah then tries to fly away, but Gigan shoots him down with the Cluster Beam, and Godzilla finishes Destoroyah off with a spinning tail attack, knocking him down. Godzilla and Gigan then drag the two monsters into a cave, and use their respective beam attacks to close in the cave on Destoroyah and Megalon. Godzilla and Gigan then look at each other, and Gigan flies off while Godzilla goes back to Godzilla Island to help fight-off against Mecha-King Ghidorah.
Gigan once again reappears in episodes 169-178 when Misato goes on an expedition to Matango Island in her ship, Gigan is seen training by throwing rocks up in the air and slicing them in two, so Misato then reports this back to the G-Guard Commander. Landes sends Camero to ask if Gigan would like to join them in conquering Godzilla Island, but Gigan is uninterested and flies off.
The Giant Dark Emperor appears in space to yell at Landes, but she cries and he gives her a new monster, Dororin, to send out on earth. Dororin then crashes on Matango Island, shape-shifts himself into Godzilla, and smashes a rock on Gigan's head while Gigan was meditating.
Then he shape-shifts into Gigan itself, and flies off. Misato also arrives on Matango Island because Lucas got an alert, and Gigan tells her Godzilla attacked it, and Gigan flies to Godzilla Island to fight Godzilla. Meanwhile back in Godzilla Island, Dororin, while disguised as Gigan, smashes a rock on Godzilla's head. The G-Guard Commander radios Misato, and tells her that Gigan is here, but she tells him she's with Gigan. Soon enough, the real Gigan comes and fights Godzilla.
So far, neither monsters are falling or getting hit by blows that brought them down in previous battles. The battle continues despite Misato getting upset, and also the fact that the G-Guard Commander is piloting MechaGodzilla to fight Dororin to protect G-Guard Base. Godzilla refuses to stop fighting to help fight Dororin. But then Moguera, piloted by Nao, comes in-between Godzilla and Gigan and tells Godzilla to help fight-off against Dororin, so Godzilla decides to go because his friends are more important than his battle honor, and Gigan follows.
While Misato uses the computer and gets a clue on how to beat Dororin, Godzilla comes in and blasts Dororin with his Radioactive Heat Ray and takes over the fight, but Dororin grabs him from behind. Then Gigan comes in and attacks Dororin. And then Fire Fighter Jet Jaguar, piloted by Misato, comes in and uses its fire hose, melting the shape-shifting monster away, the spirit then flies up to the air, only for Gigan to smash it with its claw and finally, Gigan flies away, but not before it fires an arrow with a note tied onto it to ground from space.Godzilla: Final Wars, where he was discovered as a mummified monster in Hokkaido by the Earth Defense Force. According to the Shobijin, Gigan invaded the Earth thousands of years ago, but was defeated by Mothra. Gigan was awakened by the Xiliens to help them conquer the Earth. He chased the Gotengo to Antarctica to stop it from awakening Godzilla. He nearly destroyed the ship, but he was blasted by one of Godzilla's nuclear beams. Gigan battled Godzilla, trapping him in barbed wire and pulling him toward his buzzsaw. However, Godzilla fired his atomic breath at Gigan's head, decapitating him and causing him to fall to the ground.
Modified GiganModified Gigan (改造ガイガン?) was Gigan's second form in Kaizō GaiganGodzilla: Final Wars, where he is rebuilt with a different head and chainsaws instead of hooks after being decapitated in his earlier battle with Godzilla. Gigan was released by X to battle Mothra, and seemingly defeated her after slicing off part of her wing. Gigan then attempted to help Monster X in his battle with Godzilla, slicing him in the chest while Monster X held him still. Mothra flew into the battle and knocked Monster X and Gigan over. Gigan shot his blades at Mothra, but she dodged them. Gigan then blasted Mothra with his laser beam, causing her to burst into flames. Gigan struck a victory pose, but his razor discs flew back and sliced his head off. Gigan wandered around blindly after his head was severed until Mothra, now on fire, flew into him, causing him to explode and die.
Gigan is capable of flying at speeds of up to Mach 3 while in Earth's atmosphere. However, in the realm of space, the cybernetic assassin Gigan is capable of flight at millions of times faster than light by encasing himself in a diamond. This normally assists in interstellar travel and is utilized very little, if at all, during battle situations. When it is used in battle, however, Gigan will often use it to engage in aerial slams to continuously topple his opponents without giving them a chance to counter, or even get up. Oddly enough, Gigan lacks his flying ability in the Godzilla: Destroy All Monsters Melee, Godzilla: Save the Earth, and Godzilla: Unleashed video games, though he is clearly seen flying in the opening cinematic sequence of Godzilla: Save the Earth. Another mode of movement that Gigan utilizes is his teleportation ability, only seen in the video games.
Gigan has a buzzsaw built into his abdominal area made of an unknown alien alloy; granting it considerable durability and sharpness. In his first appearance, Gigan's saw was able to draw blood from both Godzilla and Anguirus. In Godzilla: Final Wars, it was even able to lacerate the hull of the Gotengo. A favored tactic of Gigan is to use his powers of flight along with his buzzsaw in hit and run attacks, slashing his opponent as he races by them.
In the video game Godzilla: Battle Legends and the Godzilla arcade game, Gigan has the ability to spew flames from his mouth. Although this ability has never been used in a film, Godzilla Movie Studio Tour confirmed that it is a normal ability Gigan has always had.
Gigan's forelimbs sport a pair of large metal hooks in place of hands which he can use these to batter and stab an opponent. In his appearance on the television series Zone Fighter, the tips of the hooks can release an explosive charge on contact with an enemy. In Godzilla: Final Wars, instead of hooks Gigan's forearms ended in scythe like blades, the undersides of which were each equipped with dual grappling hooks which Gigan could use to bind an enemy and then drag them straight into his buzzsaw. Following his initial defeat by the recently awakened Godzilla, the blades were replaced with double-pronged chainsaws.
In addition to his melee weapons, Showa era Gigan was depicted as having an beam aperture set into his forehead just above his visor. Official art would frequently depict him as firing a laser from this device although he was never shown to actually do so on film (possibly a result of budget limits/cutbacks and/or lack of time; the illustrations could also have been done for effect). However, in a battle sequence for Godzilla vs. Gigan, after Godzilla heaves a rock at Gigan's face, the laser device in Gigan's forehead gives off a quick flash of light, possibly short-circuiting. In video games, Gigan's laser was featured in Godzilla: Monster of Monsters for the NES as well as later being used in Godzilla: Destroy All Monsters Melee, Godzilla: Save the Earth, and Godzilla: Unleashed. According to the info located on the back of Gigan's Trendmasters collectible card, Gigan's forehead laser is actually an atomic energy weapon, similar to Godzilla's own atomic breath.
In Godzilla: Final Wars, Gigan's laser blast was finally revealed on screen, though it had been heavily altered from the original concept. Rather than being fired from a forehead laser device (the aperture had been replaced with a non-faceted ruby gem), it was instead fired from Gigan's eye itself. It also was no longer a traditional laser, but a large energy blast that-in a manner similar to a cluster bomb-would split into smaller explosive bolts of energy upon entering close range of a target, saturating the target in multiple hits simultaneously. The eye beam has been officially titled the "Cluster Light Beam," and while featured in the video games, unlike its film counterpart the beam scatters the instant it leaves Gigan's eye, has a limited range, and is referred to as "Shotgun Blast." In Godzilla: The Game, Modified Gigan's laser beam is called "Giganume Cluster."
After being repaired and upgraded following his initial fight with Godzilla in Godzilla: Final Wars, Gigan displayed the ability to fire guided razor discs from two hidden slots in his upper torso which were able to boomerang back for a second attempt if they initially missed their target. Doing so however is risky as if they missed the target once again, Gigan would find himself right in the path of his own attack; which ultimately was what killed him.
In the 2014 Godzilla game, Gigan's razor disc attack is called "Blooded Slicer." He also possesses a more powerful version called "Surging Wave Blooded Slicer".
Gigan was also able to use his scorpion-like tail to aid him in melee combat.
Gigan appeared later on within the 2004 video game Godzilla: Save the Earth.
|“|| Gigan is the vanguard of the Alien Invaders. He is the finest fighting monster the Vortaak have at their command. Gigan is a cyborg infused with Vortaak technology designed to augment his powerful natural combat abilities. This latest upgrade makes him faster, stronger, and more ferocious than ever.|
Gigan projects powerful alien energy from his single eye to engage opponents at range, though with quick footwork and lightning-fast edged attacks he is clearly designed with close combat in mind.
In addition, Gigan has the ability to teleport short distances to confuse and outflank his opponents.
— Gigan Godzilla: Unleashed bio
Gigan's Godzilla: Unleashed bio differs slightly in the Wii and PS2 versions in the sense that the latter has contains a different closing sentence.
Gigan was featured within the game Godzilla On Monster Island.
|“|| This monster was a space dinosaur the Nebula M Space Hunter aliens turned into a cyborg to serve as an invasion weapon. It is equipped with mechanical weapons from head to toe, including talon hammer hands and rotating cutters in its abdominal region. The cyborg is designed to carry out joint operations with King Ghidorah, and it's operated by a special signal from "Godzilla Tower," a conning tower constructed in the invasion front line base made to look like an amusement park.|
In "Godzilla: Final Wars" (2004), Gigan was a cyborg monster for the Xilien Invasion. Notable features include the "Gigarium Cluster," a diffused light beam it can shoot from his eyes, rotating "Bladed Slicers" it its abdomen, and the talon-shaped "Bloody Triggers" that make up both its arms. 12,000 years ago it felled Mothra, and after destroying the civilization of prehistory, it ended up in a mummified state resting at the bottom of the sea until reactivated by the Xiliens during their reinvasion. Despite its first failed attempt, it was improved and powered up to go after Godzilla again.
A biological weapon with built-in combat weaponry all over its body, Gigan is a strikingly popular monster despite having appeared in only a few movies.
— Gigan Kaiju Guide bio
Gigan, using his "Modified Gigan" design from Godzilla: Final Wars, appears as a boss in many levels throughout the 2014 Godzilla game. He was the final kaiju revealed to be in the original PlayStation 3 release of the game. Gigan attacks with his buzzsaw, razor disks, chainsaw hands, and eye beams. He also charges at enemies with the blade on his head. When defeated, Gigan's head will explode, which is a reference to Godzilla: Final Wars.

Gigan appeared within the mobile title Godzilla: Kaiju Collection.
In this promotional comic by Cinema Shares International, Gigan (named as Borodan) is said to have been 'acquired' by Megalon, rather than being recruited by the Seatopians. Borodan fights both Godzilla and 'Robotman', but is defeated after he gets dropped from a great height by Robotman.
In this short manga series, Gigan is featured as an enemy of Godzilla that is under the control of Doctor Oniyama. This Gigan was called Neo Gigan, and was sent to Earth from space with King Ghidorah at the end of Volume 1. Neo Gigan fought Godzilla after Flying Ebirah was defeated, and used a variety of abilities to overpower the heroic kaiju, including firing his hooks off on cables to ensnare Godzilla, using his Optic Laser, and using his Buzzsaw.
Godzilla managed to pull off one of Neo Gigan's arms when the latter attempted to use his Buzzaw again, exposing the cybernetics inside his chest. In a bid to turn the battle in Oniyama's favour, Neo Gigan tried to attack Godzilla by launching his head off his body and firing his Optic Laser again. This failed, and Godzilla destroyed Gigan's head using his Atomic Breath, shutting the cyborg down for good.
Gigan makes a small cameo in Godzilla: Legends #1. When Dr. Anders is commenting on how Anguirus has lost every time he has fought another kaiju, Gigan's arm can be seen in one of the flash back panels, slicing Anguirus across the face.
Gigan appears in The Half-Century War #5. In this issue, Gigan and King Ghidorah arrive on Earth and wreak havoc. The AMF builds the Dimension Tide and lures the space monsters to Antarctica, hoping to trap them in an artificial black hole. Godzilla and Kiryu arrive and temporarily join forces to battle the space monsters. Eventually, Gigan is defeated and banished into the black hole along with King Ghidorah.
Gigan appears in Godzilla: Ongoing as one of the space monsters that attack Earth. In issue #10, Gigan battles Rodan and Anguirus in Hong Kong. Gigan's visor is shattered in the battle, rendering him blind. Gigan's fate is left unknown.
In the first issue of Godzilla: Rulers of Earth, Gigan erupted from underground in Arizona, his visor still damaged from the earlier battle, and was immediately attacked by Kumonga. After getting trapped in the kaiju's webbing, Gigan faked defeat until Kumonga got close. Using his abdomen saw, Gigan severed one of Kumonga's legs, and freed himself from the web. Using his laser, Gigan set the whole valley on fire and left to be upgraded by the Cryog aliens.
Gigan later appeared with the FinalGigan design in Rulers of Earth #6 to fight Godzilla and M.O.G.U.E.R.A. with the help of Orga. M.O.G.U.E.R.A. was disabled by the alien kaiju. Orga couldn't be controlled by the Cryog, though, and went on a rampage but was destroyed, leaving Gigan to deal with Godzilla. Jet Jaguar came in soon afterwards and Gigan was soon defeated by Godzilla and Jet Jaguar.
In Rulers of Earth #17, Gigan is deployed to defend the Cryogs' ship from his former ally, SpaceGodzilla. Gigan and SpaceGodzilla prove to be almost equally matched, but SpaceGodzilla uses his mastery of crystals to shred Gigan's sails before SpaceGodzilla resumes its path to Earth in its flying form. Gigan's right arm is caught in SpaceGodzilla's crystalline hide and the cyborg is forced to sever it in order to escape, leaving him floating helplessly in space.
In the final issue, it is revealed that the Cryog commander, Rhizon, rescued and repaired Gigan to use in his coup against Karkaro. After Karkaro destroyed Rhizon's ship, Gigan was released from a silo on Earth's moon, and proceeded to attack and wipe out all of Karkaro's fleet, as well as briefly battle with Jet Jaguar once again. Gigan cut into Karkaro's ship with his upgraded chainsaws, crippling the spacecraft. After a brief argument, Rhizon shoved Karkaro into Gigan's still-active chainsaw blades, killing him, but not before he summoned Magita from the Trilopod hive. At some point during the battle, Jet Jaguar confronted Gigan and defeated him yet again before he went to help the other monsters. Gigan seemed to disappear after this, but was later shown at the end of the issue being repaired alongside a MechaGodzilla in an unknown location, possibly by the Cryogs.
Gigan appeared in issue #1 of Godzilla: Rage Across Time, where he, alongside Megalon, were controlled by Zhenjin Khan, the dragon master, as he lead them and his Nebulan/Mongolian troops, as sent and ordered by the Chinese emperor Kublai Khan, to obliterate Japan in 13th century Japan. The soldiers of Japan fought back against the Mongolians while the two monsters laid waste to the land. Just when it looked like all hope is lost, the monsters were suddenly hit by an atomic beam that pushed back Megalon's napalm bomb.
The user revealed himself to be Godzilla, who was drawn towards the duo's location to fight them. At first, Godzilla had the upper hand in battle by dodging the monsters' attacks and striking hard at them, but then Megalon and Gigan fought back and soon dominated over Godzilla with their well-coordinated teamwork. When it seemed like the leviathan was about to lose to these alien monsters, the Mongol relic that controlled them was destroyed by a fire arrow shot from Akio, the infamous woman warrior.
Soon, with the monsters dazed and confused, the atomic leviathan shot an atomic breath at Gigan and swung his thick tail at Megalon. Afterwards, the two monsters decided to retreat and flew off into space while Godzilla destroyed the remainders of the invading army.
