Wario

Wario is an enemy and the main antagonist of Return to the factory and Return to the Factory 2: The Mcroy house. He was once the owner of wario's fast food factory before being stabbed to death by Bruno gate.

Appearance
In Return to the factory Wario keeps his original appearance, with a yellow undershirt purple overalls, green shoes, white gloves and a yellow hat with his signature W on it with glowing blank white eyes. In Return to the Factory 2: the mcroy house, Wario has his appearance from FNAW 3, with the same clothing but with a skinless bone face and glowing purple eyes due to the events of FNAW 2 (which is not revealed to be canon yet in the RTTF universe) when Bowser burnt his face off. When he was alive he wore the same attire only with normal eyes.

Origin
Wario once was a greedy jerk who wanted nothing to be very rich but one day he and his bro Waluigi decided to open up their own café, unfortunately due to some ghost shenanigans the place was closed down before it could even open. This did not stop Wario though and he reinvested in opening a fast food factory, assisted by his bro as well as the Mario bros and peach, Warios factory was a big success. Until one day a mysterious man(Bruno gate) snuck into the factory and used the spare Wario man costume in an attempt to steal Warios secret recipe. Wario eventually arrived and saw what had happened, Bruno had stabbed Waluigi and peach, hung luigi by a noose and decapitated Mario before leaping at Wario, killing him. However an alternate timeline version of Wario and Co. Possessed the Deseased corpses and went to look for the murderer. Wario killed Bruno gate before he could steal the recipe and haunted the factory from then on.

Mechanics:RTTF:1
Wario starts in the top left cam along side Waluigi and will gradually make his way toward the players office, once he reaches the doorway if the player sees him in the doorway the player must close the door or else Wario will jam the door and inevitably jumpscare the player, successfully closing the door will eventually force Wario to leave. He can also spawn in the middle hall, where you must flick the light until it turns on to send him away. Failing to do so will end in your demise. Additionally if the player runs out of power Wario will appear in the doorway and play a little tune for a bit before eventually killing the player.

Mechanics:RTTF:2,The mcroy house
Night 1 Entrance: Wario along with Waluigi will be active in the entrance on night 1. Wario will start at the bedroom before moving to the hallway, the kitchen and the parlour before arriving at the entrance, upon reaching the entrance Wario will appear on the side of the room prompting the player to look away from him and not bring up the camera until he leaves. Failure to do either of those things will result in an instant jumpscare.

Night 2 bathroom: Wario alongside Yoshi will be active in the bathroom on night 2, should the player decide to hide there. Wario spawns in a room away from the player and will make his way to the bathroom and eventually enter it. When wario enters the bathroom his face will appear in the mirror, when this happens the player must use the cold water valve on the sink and keep it running until Warios' face is no longer visible in the mirror (around when it gets towards blue only). Failure to turn the cold water on or not keeping the cold water on for long enough will lead to a jumpscare by Wario.

Night 3 Dining room: Wario alongside Waluigi will be active in the dining room on night 3, if the player enters the room after clearing the bathroom on the previous night. Wario will start in bedroom 2 before moving to the game room and then entering the dining room. If Wario enters the dining room the player must spam the camera pad until he goes away, failure to do so will result in a jumpscare from Wario.

Night 3 Parlor: Wario alongside Ashley will be active in the parlour on night 3, if the player enters the room after clearing the kitchen on the previous night. Wario will start in a room away from the player and will slowly make his way toward the parlour, once he reaches it he will become visible in the doorway on the right, when he appears turn on the lamp and keep it on until he leaves(this is shown via a scene of Wario walking out the door) but failure to do so will result in a jumpscare.

Night 3 Study: Wario alongside Luigi will be active in the study on night 3, if the player enters the room after clearing the bathroom on the previous night. It is unknown which room Wario starts in due to the black out that happens when you enter the study and can only be seen through brief flashes on the camera. Wario will soon enter the study upon reaching it and will hide in the darkness on the left side of the room, if the player hears him enter the player must turn on the lantern and shine the light on him until he leaves. Failure to do so results in a jumpscare.

Night 4 Hallway: Wario alongside Luigi and Mario will be active in the hallway on night 4, if the player enters the room if you chose the kitchen on night 2. Wario will randomly appear in the game room or the bedroom and will stare into the camera in the room he's in, if Wario appears in either of those rooms the player must go to that camera and watch Wario until he goes away. Failure to watch Wario for long enough or at all will result in Wario bashing through the door of the room he's in running down the hallway and instantly killing the player via jumpscare.

Night 5 The Cellar: Wario appears alongside all the other spirits(excluding DK)in the cellar on night 5 which will always be the end point of the game no matter which path you took on night 2. On phase 1 of the cellar(the storage area that goes through 12 A.M to 2 A.M)Wario will attack the player with Luigi, Wario will appear at random but never at the same time as Luigi, the player must use their night vision Camera to see if Wario is in the area with them, if he is then the player must quickly press the yellow flash button to flash the lights and scare off Wario.(be careful when doing this as the buttons are scrambled on night 5 due to the player going insane)Failure to flash the light in time will result in a jumpscare by Wario. In the second phase of the cellar(the boiler room that goes through 2 A.M to 4 A.M) Wario does not appear as Ashley and Yoshi take their turn. In the third and final phase of the cellar that goes through 4 A.M to 6 A.M dubbed, RETURN TO THE ENTRANCE, Wario and the other spirits launch an all-out-attack on the player and Wario teams with Yoshi to attack from the left, if Yoshi or Wario are seen or heard at the left side of the room, click the blue flash left button to scare them off before they jumpscare you ending your run.

Endings
RTTF 1

Wario appears at the end of the game showing how he was murdered but that's about it.

RTTF 2:The Mcroy House

In the bad ending, which is achieved if you don't find all the music box parts, Wario is leading the other spirits and soon encounters Rosalina. Who he aggressively shoulder charges, prompting Rosalina to open a time gate. Which sends the spirits of Wario and friends back to the past, redoing the time loop that goes on forever. Am image of Wario's café shows up alongside Wario from FNAW:Origins.

In the good ending, which is achieved by finding all the music box parts, Wario, Mario, Luigi and Waluigi have a reunion with Bruno gate who was led to the house by the sounds of the music box, and he apologizes to them freeing their spirits and finally breaking the time loop once and for all(with peach, Ashley and Yoshi being freed off screen. DK is not here cause he was just a hallucination from inhaling too much smoke in the kitchen).

Trivia
Wario's death clashes with his death in the original FNAW, in RTTF the cutscene after night 5 shows he was killed by Bruno gate last, but in the original FNAW phone guy explains in his night 3 phone call that Wario went missing first at the same time as Waluigi

Wario shoulder charging Rosalina is based off the final pre-night cutscene from FNAW:Origins where the same thing from RTTF 2's bad ending happens.

Wario's skeletal appearance in RTTF 2:The Mcroy House is based off his appearance from FNAW 3, which according to wwwWarios (the creator the original Five Nights at Warios) full FNAW story video was created after bowser breathed fire and accidentally burned off Warios skin.

The tune wario plays when the power runs out in RTTF 1 is a slowed down version of the toreador march from the oprah carmen. This theme is also played by freddy when the power goes out in the original FNAF, while the same version is played by Wario in the original FNAW.

Wario appears to be the only spirit with actual animation in RTTF 2, this is shown by him running down the hallway and him walking out the door after fending him off in the parlour.
