It's basically FNaS 3, but with different characters from different games. The creator of this FNaS AU is josefausto.

The fanart is only made by me

The origin of this FNaS AU is simple: Josefausto created it back in the FNaS era when the Amino app was still around. I found the story—based on FNaF 3—interesting, but there was another key detail: the characters. The designs were created by Josefausto, and even though the Amino app was deleted, I’ve managed to keep the memory of this FNaS AU alive.

Characters lore:

Springexecutor: Formerly known as Origin Mario or Spring Mario, he appears as a soulless suit. He was found in the forbidden room of an old, dilapidated pizzeria where he and his friend Origin Sonic used to live. He looks this way due to a springlock failure, Its bones crushed someone who got inside the suit. That "someone" is an "EXE"; the person who entered the suit remains unidentified, but it is someone the Phantoms remember—and they can't stand him.

Phantom Tux: Originating from a platformer called *SuperTux*, he had a fatal end; he was killed by an entity that lured him to the abandoned pizzeria solely to satisfy its own twisted desires.

Phantom Faby: Originating from a game called *Flabby Bird*, he met the same fate as Tux.

Phantom Sonyc: Despite looking like Sonic, he is a distinct character from a game called *Sonyc MSX*; he suffered the same death as Tux and Faby.

Phantom Hikaru and Akane: Both are from the game *Parodius* and met the same fate as the others.

Summary: the Phantoms hate Springexecutor.

For now, it's according to the owner of this fnas au.
