The **Guardian Units of the Nations**, also knonw as **Guardian Units of Nation**,often abbreviated as **GUN** or **G.U.N.**, is a group in the *Sonic the Hedgehog* series. It is a worldwide military and law enforcement organization. Run by a man only known as the Abraham Tower, G.U.N. seeks to protect the earth from all sorts of threats, including Dr. Eggman, Black Arms and the Dark Gaia Creatures.

G.U.N. has vast resources, including an army of soldiers and peacekeepers, fighter planes and other instruments of warfare. While G.U.N. receives orders from the President of the United Federation, it operates under the sole discretion of the Commander, who has been known to use G.U.N.'s resources to bring down enemies.

## History

### Past

Fifty years ago, GUN forces was called in to deploy troops to Space Colony ARK in order to stop Project Shadow , a research project led by Professor Gerald Robotnik that aimed to create the "Ultimate Lifeform", because the government deemed it as a threat. They apprehended most of the researchers (except for Gerald, who would be taken to Prison Island to be sentenced to execution) and stopped their research projects before sealing the prototype of the Ultimate Lifeform away in the ARK. G.U.N. also were responsible for the resulting deaths of the professor and his granddaughter, Maria Robotnik. Prior to his death, however, Gerald prepared a means of revenge against G.U.N. and the rest of the world using his creation Shadow the Hedgehog and Space Colony ARK. In the aftermath, GUN would shut down the ARK for the next fifty years.

### *Sonic Adventure 2*

When Shadow was reawakened by Gerald's grandson, Dr. Ivo "Eggman" Robotnik, GUN were responsible for the mistaken capture of the world-renowned hero, Sonic the Hedgehog, which lead G.U.N. to inadvertently arrest the wrong hedgehog. They send in a government spy, Rouge the Bat, to spy on Dr. Eggman and Shadow, and to retrieve information on Project Shadow via the Ark's database. This resulted in clashes between G.U.N. forces, as well as both Eggman and Sonic's allies(although, many factors, such as GUN's mistaking of Sonic for Shadow, and Tails' attack on Prison Island, might have provoked this), one of which resulted in the destruction of Prison Island. This proved them to be have caused more harm than good in general although, unintentional. However, G.U.N.'s error was subsequently made clear when Super Sonic and Super Shadow worked together to save the world from the plummeting ARK.

### *Shadow the Hedgehog*

The role of GUN in *Shadow the Hedgehog*'s plot is to repel the invasion of Earth by the forces of the Black Arms by any means necessary - including the (presumably unwanted) assistance from Sonic and his friends. During the opening FMV sequence, it is shown that Earth is being overrun, with G.U.N.'s forces almost helpless - hence the temporary alliance. It is also strongly hinted during the game and FMV sequences that G.U.N.'s mission is the investigation (and possible destruction) of Shadow himself, depending on the player's moral choices within the game. Their attempts at doing this are caused by the Commander of G.U.N. due to his personal hatred of Shadow, although in two endings he realizes Shadow isn't evil and it was simply a misunderstanding.

### *Sonic Rush*

Huge Crisis Zone is a stage centered on infiltrating several of the organization's battleships at sea. The enemies look similar to G.U.N. Hunter and Hawk robots, and they do not release animals or Chaos Drives when defeated. It is unknown why they attacked Sonic and Blaze, but the name of the stage implies that, either through their unnecessary intervening with the events of the story, or by Dr. Eggman and Eggman Nega taking over the G.U.N. Battleships and control of its G.U.N. robots, that further delay on the situation could have blown up into a more grave scenario.

### *Sonic the Hedgehog* (2006)

This resulted in Shadow has now being recruited as an agent of G.U.N., working alongside Rouge the Bat and Eggman's rebellious creation E-123 Omega. Whom they requisition to find Rouge the Bat as she has presumably been kidnapped by Eggman and being held at his base in White Acropolis. After Rouge is rescued and the Scepter of Darkness is retrieved, G.U.N. appears even less. At this point, they are occasionally contacted by Shadow and Rouge for various purposes.

### *Sonic Riders: Zero Gravity*

G.U.N. is mentioned in the opening cutscene on the radio, when the newscast says that G.U.N. is investigating the out-of-control-robot problem. It is referred to as "[an] international security organization."

### *Sonic Chronicles: The Dark Brotherhood*

G.U.N. is involved during the events to help Sonic and friends find Knuckles. They are first seen helping in destroying the Egg Carrier. They appear later fighting off the Nocturnus Clan and have a headquarters in Central City as well as taking patrol in Mystic Ruins. They are investigating Knuckles' disappearance and hired Team Chaotix to learn more about the Marauders. Just before Sonic and friends traveled to the Twilight Cage, they gave Rouge instructions to gather any Marauder technology for the scientists to research and possibly re-engineer.

### Countdown to Chaos

Thanks to the efforts of the Woodland Kingsmen, a G.U.N. aircraft carrier was able to move in close enough to Avalon to deploy aerial forces that began harassing the Eurish Egg Army. However, this was brought to an end by Dr. Eggman, who single-handedly attacked and sank the carrier, seizing a plane as he did so in order to journey northward.

### Shattered World Crisis

#### Act One

In the midst of the event, GUN initiated Operation: Triage, in which they provided support in keeping the world in order. However, this resulted in air and ground forces spread thin, which allowed the Egg Army the opportunity to seize more territory on Sonic's World. Fortunately, G.U.N. received some help from the Freedom Fighters, whose relief efforts in Station Square helped pave the way for the arrival of Amanda Tower in the *Letter of Gabriel.* Days later in Westopolis, however, G.U.N. and local law enforcement came to stop an attack by mysterious monsters.

Meanwhile, G.U.N. Commander Abraham Tower enlisted Team Dark and the Spider Troupe to invade the New Black Comet and set a detonator to nuke it, (the exact tactics directed by Dr. Julian Snively). Despite some complications, they were able to succeed in their mission.

Despite their actions, one of the Black Arms, Eclipse the Darkling, and new race named Dark Arms, managed to escape the explosion and landed on Angel Island. Having determined this, G.U.N. dispatched Team Dark with a Tele-Pod that allowed Snively to communicate with them to the island to locate and finish Eclipse and his charges. When it became evident that Eclipse intended to seize the Master Emerald, Snively ordered Team Dark to relocate it to a G.U.N. facility, something that Shadow agreed to but was thwarted in by Knuckles the Echidna. Eclipse subsequently managed to seize the Emerald, only for Knuckles to shatter it to keep it away from him and G.U.N. Eclipse managed to escape in a G.U.N. craft used by Team Dark to travel to the island, while G.U.N. forces later arrived to transport the remains of Eclipse's ship to a secure facility.

A G.U.N. unit later located the last Chaos Emerald sought by the Freedom Fighters and Dr. Eggman, and told of their find to the Freedom Fighters. Unfortunately, the group was attacked by Metal Sonic, who overpowered them. The Freedom Fighters arrived in time to provide help and contacted G.U.N. to take care of the wounded.

## Personnel

### Abraham Tower

*Main article: Abraham Tower*
**Abraham Tower** is an efficient officer commander, never backing down in the face of danger. In his debut, he commands his forces against the Black Arms, serving as the counterpart to Dr. Eggman, Black Doom, and Shadow the Hedgehog. He also harbors a deep hatred towards the enigmatic hedgehog. His hatred of Shadow was so great in *Shadow the Hedgehog* he sent G.U.N. forces after him even though the world at large considered Shadow a hero.

Commander claims he saw Black Doom with Gerald Robotnik releasing Shadow. When the government came to shut down the ARK and killed Maria, he blamed Shadow for her death, as well as the deaths of all other ARK inhabitants, when, ironically, it was the G.U.N. army that killed most of them. It is unknown why he was on the ARK, but it can be assumed that he was related to one of the researchers connected to Project Shadow, since he said his family was killed along with Maria. It is unknown why he himself was evacuated instead of killed.

In some storylines, he controls the Diablon robot, G.U.N.'s most powerful creation despite it being unfinished. In three of the endings of the games, he teams up with Sonic to fight Shadow. It is unknown whether he controls it personally or via remote, as both are implied through dialogue/lack thereof.

Once he speaks to Shadow before Cosmic Fall, he realizes that Shadow isn't evil at all and regrets attempting to kill him. After Shadow defeats Devil Doom and destroys the Black Comet, the President states how ironic it was that people treated Gerald like he was evil, and he ended up saving them all in the end. The Commander and the President realize they were wrong about Gerald's intentions and that he was truly a good-hearted person. They decide they will help create peace for the world in honor of Gerald. In Expert Mode, it is revealed that the Commander had become a grandfather one week before the events of the game.

Notably, the Commander appears to have heterochromia, as he has one green and one brown eye.

### Rouge the Bat

*Main article: Rouge the Bat*
**Rouge the Bat** has been a G.U.N. agent for a very long time, and seems to have been working for G.U.N. at least since. She is one of the most valuable agents of the organization, and she is apparently highly ranked, as she often takes orders from the President himself. Her status seems to be that of a spy. Despite their affiliations, however, they do sometimes come into conflict with each other: A notable example being when she participated in the heist on Prison Island while on an undercover assignment for the President herself, and they attacked her with a Flying Dog mech.

### Shadow the Hedgehog

*Main article: Shadow the Hedgehog*
Shadow the Hedgehog has become a G.U.N. agent years before the events of *Sonic the Hedgehog*. In the aforementioned game, he was sent on a mission to rescue Rouge from Dr. Eggman's base in White Acropolis. It is unknown what Shadow's status or ranking is.

### E-123 Omega

*Main article: E-123 Omega*
E-123 Omega joins G.U.N. before *Sonic the Hedgehog*. While in there, Rouge asks a G.U.N. agent to contact E-123 Omega.

## G.U.N. Troops

G.U.N.'s forces consist of both human soldiers and a large variety of robots that are just as complicated and powerful as those of Dr. Eggman. The G.U.N. robots are powered by "Chaos Drives ", power cores invented by Gerald Robotnik after researching Chaos Emeralds.

### GUN Soldiers

Foot troops of G.U.N. armed with combat knives or a variety of firearms. They first appeared in a cutscene in *Sonic Adventure 2*, and reappeared as common enemies in *Shadow the Hedgehog*. They mostly wear black and blue, but they also have green, tan, black and brown camouflage clothes for jungle areas, and commonly are armed with pistols, sub-machine guns, assault rifles and over-shoulder explosives. Some also are equipped with riot shields to protect them from frontal attacks.

### Beetle series

These are saucer-shaped one-eyed floating robots that appear in *Sonic Adventure 2*, and *Shadow the Hedgehog*. They function as obstacles that block your path forward or serve as tiny attack platforms.There are several different types of beetles, which hover with a fan, but unlike the Wing that has turbines, they can't move. The Beetles in *Shadow the Hedgehog* also have the number "05" on them.

### Hunter series

Hunters are tall white humanoid robots. They have the number "02" on them. A Hunter is 3.5 meters (11' 11") tall, 2.5 meters (8' 8") wide, and weighs 2.5 metric tons (2.75 short tons).

 Shield Hunter | *Sonic Adventure 2* | Hunter equipped with a large powerful shield. It can use either a gun or a laser. Can only be destroyed at their feet when they lower their shield to open fire.

### Rhino series

Rhinos are blocky tank-like robots. They usually attack by attempting to ram into their target. They have the number "03" on them.

 Rhino Spring | *Sonic Rush* | Rhino with a jet-propelled spring on top.

### Hawk series

Hawks are large floating G.U.N. robots that don't really look like anything else. They appear to have two cylinder-shaped engines that they use to hover and maneuver in the air. They have the number "04" on them.

 Bomb Hawk | *Sonic Rush* | Hawk that hovers in the air while dropping bombs.

### Hornet series

Hornets are flying eye-like robots with several appendages that hold bombs. When they spot an enemy, they fire the bombs toward it. They have the number "05" on them.

 Hornet-6 | Sonic Adventure 2
 Laser Hornet | *Sonic Adventure 2* | Hornet armed with three laser guns instead of bombs.

### Artificial Chaos series

Artificial Chaos are robotic versions of Chaos from *Sonic Adventure* that exist on the Space Colony ARK and all are prototypes of the Ultimate Life Form. See Gerald Robotnik for more information.

 Cell | *Sonic Adventure 2, Shadow the Hedgehog* | A tiny cell of an Artificial Chaos. Many are created by the P-100.

## Vehicles

### Big Foots

The Big Foot walkers are large bipedal walkers. They can also hover in the air. In *Sonic Adventure 2* and *Shadow the Hedgehog*, they are manned by a G.U.N. pilot, but sometimes, they appear to be completely robotic or remote-controlled, somewhat weaker, and mass-produced.

**Big Foot Type A**
A newer version of the Big Foot colored teal, yellow and red. It appears in *Shadow the Hedgehog* and usually guards later levels. They are the second strongest standard enemy belonging to G.U.N. In Shadow the Hedgehog, they carry Gatling guns which Shadow can pick up after he has defeated them. It's much stronger than the *Sonic Adventure 2* variant, and takes many more homing attacks to defeat.

**Big Foot Type B**
The Type B is similar to the F-6, except it is camouflage-colored and is armed with two quad missile launchers on its "shoulders". It appears in *Shadow the Hedgehog* as fairly uncommon enemy. It is also the strongest unit belonging to G.U.N. It never uses its Gatling gun, but fires homing missiles very quickly. After being destroyed, it drops a lock-on missile launcher.

**Spider Troops F-6t Big Foot**
The F-6t is similar to the Type B, but is teal, yellow and red instead of camouflage-colored. It attacks by flying above Sonic and firing its Gatling gun, occasionally landing to fire its missiles. It appears as one of the first bosses in *Sonic Adventure 2*, where it was fought and destroyed by Sonic. This Big Foot is 3.4 meters (11' 11") tall, 4.8 meters (16' 3") wide, and weighs 9.2 metric tons (10.14 short tons).

### Others

**Scorpion Troops B-3x Hot Shot**
Nearly identical to an F-6t Big Foot, except for a particle beam cannon built into the torso. Appears only in *Sonic Adventure 2*, where it was fought and defeated by Shadow the Hedgehog. It is very similar to the Big Foot fought by Sonic, but the main difference between the two is that Big Foot makes three overhead machine-gun passes before landing and firing missiles, while Hot Shot only passes overhead once, but is armed with a powerful laser cannon. The Hot Shot is 3.4 meters tall, 4.8 meters wide, and weighs 9.6 tons.

**Jump Vehicle**
A small walker that can jump to very high heights, and has some hovering capabilities. It appeared in *Shadow the Hedgehog*, where Shadow can use it for himself.

**Jump Vehicle (with cannon)**
A walker very similar to the Jump Vehicle, but armed with two machine gun turrets. It cannot jump nearly as high as the Jump Vehicle, but it has hovering capabilities. It appeared in *Shadow the Hedgehog* along with the Jump Vehicle.

### Hovering Mechs

**R-1/A Flying Dog**
A flying mech identical in equipment to Hot Shot, with the exception of not needing to land, completely lacking legs. It appears in *Sonic Adventure 2*, where it traps Rouge the Bat on Prison Island, but is defeated. It is 3.6 meters in both tallness and wideness, and weighs 5.4 tons.

**Mantis Platoon HD1 Heavy Dog**
Appears in *Shadow the Hedgehog* in one of Shadow the Hedgehog's flashbacks. The Heavy Dog is a large, disc-like machine that tries to stop Shadow and Maria Robotnik from escaping the Space Colony ARK, but it is destroyed by Shadow. The Heavy Dog is armed with several homing missile launchers all around its body, and can drop floating mines that explode after some time. Its most dangerous armament is its Particle Beam Cannon, a weapon that fires blue energy waves in all directions. Interestingly, blueprints for the Heavy Dog can be seen on the walls of room it is fought in. Presumably, the Heavy Dog was built aboard the ARK, corresponding with what Shadow said about "weapons of mass destruction" being built on the ARK.

**LZ-12R Blue Falcon**

Also appearing in *Shadow the Hedgehog*, the Blue Falcon is a different version of the HD1 Heavy Dog, exchanging the bomb-launching en masse capabilities of its counterpart for enhanced speed and strength. It is assigned to guard the Eclipse Cannon from invaders. The Blue Falcon is armed with the same missile launchers and Particle Beam Cannon as the Heavy Dog, but has the ability to drop powerful bombs instead of floating mines.

* The Blue Falcon is said to be named after Captain Falcon's car in *F-Zero* of the same name, possibly since Sega happened to help develop *F-Zero GX* and *F-Zero AX*.

**U78-X/D Diablon**
The mech U78-X/D Diablon appears in *Shadow the Hedgehog* as one of the possible final bosses. It is a humanoid robot, fully equipped with a powerful energy shield, a jet-pack, a strong laser gun and its most powerful feature; the Antimatter Cannon, which after some necessary charging up creates an explosion of energy causing destruction within a large radius. Diablon is controlled by GUN's Commander (whether remotely or internally is unknown, as both ways are implied by dialogue/lack thereof), and is accompanied by Sonic when fought by Shadow. Its serial number and name are displayed on its wrists. It can be confronted in the GUN Fortress, Final Haunt and Black Comet stages. Many fans consider it the most powerful GUN robot there is, even though it was incomplete, speculating it may be stronger if it was completed.

### Others

 G.U.N. Fort | Sonic X
 Mobile Rocket
 Gun Turret
 Gun Lift | Shadow the Hedgehog

## Weapons

### *Sonic Adventure 2*

 Laser
 Gum Laser
 Bomb
 Minigun
 Missile launcher
 Particle beam cannon | An energy weapon that is used by Hot Shot and Flying Dog. It takes time to charge, but the blue energy shot fired creates a large explosion, and has some homing capabilities.

### *Shadow the Hedgehog*

*Shadow the Hedgehog* revealed a much larger and more realistic arsenal of weapons for G.U.N .(and Shadow) to use.

## Bases

### GUN Fortress

*Main article: GUN Fortress*
G.U.N.'s headquarters appears in *Shadow the Hedgehog* and is considered the most secure shelter on Earth. The President is taken there for safety when the Black Arms attack Central City. The underground fortress is heavily guarded by three mother computers, armed security cameras, and an immeasurable number of G.U.N. troops and mechs. It is located in a mountain near the sea, as seen on the platform where the goal ring is located. It serves as one of the five final stages of the game.

### Prison Island

*Main article: Prison Island*
A large jungle island used as a prison and research base by G.U.N. In *Sonic Adventure 2*, Dr. Eggman first came there to find G.U.N.'s secret weapon, which turned out to be Shadow the Hedgehog. Some time later, Sonic the Hedgehog was captured by GUN due to a misunderstanding and imprisoned deep inside the island, but he was quickly rescued by Miles "Tails" Prower and Amy Rose. At the same time Shadow, Eggman and Rouge the Bat attacked the island in order to take G.U.N.'s Chaos Emeralds. They succeeded and planted several explosives on the island, blowing it up as everyone escaped.

However, *Shadow the Hedgehog* revealed that the explosives had only destroyed G.U.N.'s main base and spilled toxic waste into the rivers. G.U.N. still has some overgrown paths and prison cells in the jungle, and they use them to hold captured Black Arms soldiers. In the game, Charmy Bee goes to the island to look for some hidden data disks on behalf of Vector the Crocodile, and the player can choose to help him find them.

## Trivia

* The full name of the organization was a source of confusion. In the 2012 re-release of *Sonic Adventure 2*, the helicopter at the start of the Hero story as a clearer texture than earlier versions reading "**Guardian United Nation**". The official strategy guide of *Sonic Adventure 2* in Japan also introduced it as "**Guardian Units of Nation**". The former is considered an error made by the port team, and the latter is thought to be a small translation error involving singular and plural.
* The origin of GUN's name probably stems from the Japanese word for "army" which is simply "gun" or "guntai" and then words were made to fit with the acronym.
* Though the name is pronounced "gun" in most games they are in, the name was pronounced "G-U-N" in *Sonic the Hedgehog* (2006) and *Sonic Riders: Zero Gravity*.
* G.U.N. is based on the United States government, though they have been seen using Russian Aircraft in *Sonic Adventure 2*.
* G.U.N. may also be based on the United Nations since both are factions that fight for the peace of the world. A major difference being that G.U.N has an abundant army, to the point of even having robots and battleships while the UN only has a small army of peacekeepers. It being an implied multinational military might also be a reference to NATO and the Military of the USA, both of whom have been criticized for their hypocritical method of using military might to maintain world peace. This reflects the irony of G.U.N.'s name as while 'Guardian Units of Nations' sounds heroic compared to GUN, which is obviously a dangerous weapon.
* G.U.N. may also be a reference to-or based upon-S.H.I.E.L.D. from the Marvel Universe.
