### Fragmented Devil Form (American percentage-20%)

When 20% of its body is summoned by the President of the United States, the Gun Devil resembles an enormous floating humanoid figure with multiple building-sized rifles for arms, a roughly skeletal body crammed full of disembodied screaming heads, and an oversized barrel and slide 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 7.62×51mm NATO ammo belts attached to the bottom of its 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.
