Devil Form (American percentage-20%)
When 20% of his body is summoned by the President of the United States, the Gun Devil resembles a floating humanoid figure with multiple building-sized rifles for arms, a roughly skeletal body crammed full of disembodied screaming heads, and an oversized gun barrel emerging from its skull-like face. The Gun Devil is also missing the lower half of its body and is instead replaced by 6 long giant ammo belts attached to the Gun Devil’s torso.

The main parts of both its arms appear to be M4 Carbines, with other well-known assault rifles in its arms well. These include: the AK-47, the M16A1, and the Mk18 assault rifle. Both arms appear to wield the same rifles. The Gun Devil's head appears to be the slide and barrel of a large M1911 missing the hammer. Any firearms attached to its back are unidentifiable.

Fiend Form (Aki Hayakawa)
After the Gun Devil took over Aki Hayakawa’s body and becomes the Gun Fiend, its hair is let down with its eyes and forehead covered in dark veins. The barrel and slide of an M1911 is seen sticking out of its face in between its eyes with the gun’s hammer sticking out the back of its head, its left forearm is replaced with an M16A1.

History
Thirteen years before the present day, the whole world tried to cash in on guns as a countermeasure against devils. This led to an increase in gun use during crimes and civil revolts. Due to heavy media coverage of gun crimes in every country, worldwide fear of guns has increased drastically.



On November 18th a large terrorist attack involving guns occurred in America, causing that to be the day that the Gun Devil first appeared. The Gun Devil hit Japan for 26 seconds, killing 57,912 people. Aki Hayakawa witnessed the Gun Devil destroying his house and killing his family as it passed by. It hit several countries around the world in succession eventually leading a death toll of 1.2 million lives in only five minutes. Aldo, Joey, and their brother survived the Gun Devil's attack but lost their home along with their father, mother and grandmother. This would be one of the events in their lives that would lead them to believe that they're immortal.

After that the Gun Devil disappeared but its impact on human society led to an overall increase in fear in all devils. An international law has been prepared to strictly control the manufacturing of arms in every country to lower the fear of guns.

At some point of time, the Gun Devil has been taken down by someone unknown and he was found by the Soviet Union while he was in an unconscious state. His body is separated into several pieces and held by countries and devils. Specifically, 20% of his body is owned by the United States, 28% is owned by the Soviet Union, 11% is owned by China, 4% is owned by other nations and the remaining 37% is in the form of pieces of meat in the hands of devils scattered around the world.

However, Makima "failed" to defeat the Gun Devil. His remnants possessed the corpse of Aki Hayakawa and they become a Gun Fiend. Swiftly, the fiend moves towards Aki's residence, and arrives with a knock at the door. Denji, after being told to by Makima, opens it, and after a few short seconds, is shot in the stomach by the Gun Fiend. This attack destroys a large amount of Aki's residence, and sends Denji and Power flying through the air in the direction of the attack.
