Waluigi

Waluigi is an enemy and the secondary antagonist of Return To The Factory and Return To The Factory 2:The Mcroy House. He worked as the co-owner of wario's fast food factory until he was stabbed to death by Bruno Gate.

Appearance
Waluigi retains his original appearance with a purple undershirt, dark blue overalls, brown shoes, a purple cap with an upside down L on it, blank white eyes and much longer limbs making his lanky appearance just a bit more creepy. His appearance does not change much in RTTF 2 other than Waluigi having some blood around his mouth.

Origin
Along with his brother Wario, Waluigi used to be a greedy jerk who wanted nothing other than more money, but one day he and Wario decided to open a cafe. But due to some ghost shenanegins the cafe was closed before it could even open, Waluigi wanted to give up but decided agaisnt it and with the help of the Mario bros and peach, Waluigi helped his brother to reinvest in a fast food factory which became a booming success. Until one day a mysterious man(Bruno Gate)entered the factory and stole the Wario man costume in order to steal Wario's secret recipe. Waluigi was working when he heard noise and went with the others(excluding Wario)to go check it out, seconds later when Wario went to look for his friends, Waluigi had been stabbed to death by Bruno along with peach leaving him unable to do anything as Wario was killed by Bruno. Though not confirmed in the 'RTTF' Canon, it is most likely Rosalina reset the timeline, sending the spirits back to the Café, seeing their past selves get murdered by the killer, they entered their old bodies and came face to face with Bruno, where Waluigi watched Bruno gate get killed by Wario and haunted the factory ever since.

Mechanics
RTTF 1

Waluigi starts moving on night 1 and spawns in the same cam as Wario and slowly makes his way towards the players office until reaching the right doorway or going into the hall entrance (from the back). Once Waluigi reaches the doorway he will be visible outside the door and once the player sees him they must close the door and keep it closed until he leaves. Failure to close the door in time will result in Waluigi jamming the door and eventually killing the player via jumpscare.

RTTF 2:The Mcroy House

Night 1 Entrance: Waluigi alongside Wario is active in the entrance on night 1. Waluigi starts in bedroom 2 before moving to the game room, bathroom 2 and the study before arriving at the entrance, upon reaching the entrance Waluigi will be seen in the doorway under the staircase, when he appears here flip up the camera pad and wait until the second heartbeat to flip the pad down. Failure to flip the pad up or putting it down too early will result in a jumpscare by the long purple brother.

Night 2 Kitchen: Waluigi alongside Luigi is active in the kitchen on night 2 if the player chooses to hide there after clearing the entrance. Waluigi will start in a room away from the player and will slowly make his way toward the kitchen, upon reaching the kitchen Waluigi will act in a similar way to Luigi, needing to turn the oven on or add coal in the oven to create a smokescreen, causing him to flee. However he stays longer than luigi. Failure to add fuel in time or not adding enough fuel will result in a jumpscare.

Night 3 Dining room: Waluigi alongside Wario is active in the dining room on night 3, if the player hides in the room after clearing the bathroom on the previous night. Waluigi starts in the parlour before moving to the pantry. the kitchen and then arriving at the dining room, if the player sees Waluigi nearing the room the player must hide in the closet and stay there until Waluigi leaves the room. Failure to hide in the closet in time or going out of the closet before Waluigi leaves the room will result in a jumpscare.

Night 4 Bedroom 2: Waluigi alongside Mario is active in bedroom 2 on night 4 if the player chose the kitchen on night 2. Waluigi will start in a room away from the player and slowly make his way to bedroom 2 and upon reaching it he will appear in the doorway in front of the player, prompting the player to quickly turn the noise on in order to scare him off. Failure to do so will result in a jumpscare.

Night 4 Bathroom 2: Waluigi alongside Mario and Wario is active in bathroom 2 on night 4 if the player chose the bathroom on night 2. Waluigi will appear in the study randomly throughout the night, if he appears the player must use the lock pad to lock the study door in order to prevent Waluigi from getting into the room. Failure to lock the door in time will result in a jumpscare.

Night 5 The Cellar: Waluigi appears with all the other spirits(excluding DK who is a Phantom)in the cellar on night 5 which is the final room regardless of which room you chose on night 2. Waluigi does not appear on the storage area or boiler room phases(12 A.M to 4 A.M)but does appear on the final phase dubbed,RETURN TO THE ENTRANCE, where the spirits launch an all-out-attack on the player, and Waluigi teams up with Mario to attack from the center. If Waluigi or Mario is heard or seen in the doorway in front of you the player must click the flash middle button in order to scare them off or else they will end your run with a jumpscare

Endings
RTTF 1

Waluigi does not appear during the post night 5 cutscene but his body is seen on the floor along with the others and he can be briefly seen right before Wario kills Bruno gate.

RTTF 2:The Mcroy House

In the bad ending, achieved by not finding all of the music box parts, Waluigi is seen walking along with the other main spirits before encountering Rosalina, to which Waluigi steps back in shock before being sent back in time along with the others by rosalina continuing the endless time loop.

In the good ending, achieved by finding all of the music box parts, Waluigi, Wario, Luigi and Mario reunite with Bruno gate who was lead to the house by the sounds of the music box. Bruno apologizes to the spirits which sets them free breaking the time loop(peach is freed and the curse is lifted off Yoshi and Ashley off screen, DK is not here cause he's just a hallucination from inhaling too much smoke in the kitchen).

Trivia
Waluigi appears in memory flashes during the final cellar phase with his mouth open.

Waluigi having blood around his mouth is probably from previous victims but this is still undetermined

Its unknown what Waluigi did as the co-owner of the factory but its presumed he would take over for Wario if he fell too sick or injured to go to work

Waluigi is the only other spirit besides Wario that can show emotions, which is seen in the bad ending of RTTF 2

Waluigi tends to move slower than Wario but mostly gets to the door first anyway

Waluigi can be seen through the closet doors when hiding in the dining room when he's walking through it.
