Mario

Mario is an enemy and antagonist in Return to the Factory and Return to the Factory 2:The Mcroy House. He served as a mechanic at wario's factory before being decapitated by bruno gate.

Appearance
Mario has gotten a big model change, he still wears his titular red undershirt, blue overalls, brown shoes, white gloves and red hat with his signature M on it. But he is completely missing his head with the only remnants being his moustache and floating and glowing white blank eyes. When he was alive he had the same appearance but he still has his head and has normal eyes. He retains the same appearance in RTTF 2.

Origin
Mario is the hero of the mushroom kingdom, adored by toads and other citizens alike he is always there to save peach and the kingdom whenever bowser decides to attack, he has gone on a lot of adventures with his brother Luigi and knows the kingdom very well. After Wario's cafe shut down Mario decided to be the helpful person he is and help the Wario bros as well as peach and Luigi reinvest in a fast food factory and with him as the mechanic who never gives up the factory became a huge 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 Wario's secret recipe. Mario heard noise while working and went with the others to check it out but when Wario went looking for them Mario had his head cut off by Bruno gate leaving him unable to do anything as Bruno killed Wario. Mario and the others would not rest peacefully however and they went back to their bodies and Mario watched as Wario killed bruno gate.

Endings
RTTF 1

Mario is not seen during the post night 5 cutscene but his body can be seen on the floor with the others and he briefly appears behind Wario before he kills Bruno gate.

RTTF 2:The Mcroy House

In the bad ending, achieved by not finding all of the music box parts, Mario is seen walking with the other main spirits until they encounter Rosalina, to which Mario reacts with an aggressive pose before he and the others are sent back in time by Rosalina, continuing the time loop.

In the good ending, achieved by finding all of the music box parts, Mario, Wario, Waluigi and Luigi reunite with Bruno gate who apologizes to them and sets their souls free, breaking the time loop for good.(Peach, Ashley and Yoshi are freed offscreen and DK is not here because he's just a hallucination from inhaling too much smoke in the kitchen.

Trivia
Mario tends to keep out of sight while moving around probably due to him wanting to take the player by surprise.

The theme he plays when he's about to kill the player during the laundry room power outage is his original theme but slowed down.

Mario is sensitive to noise despite not having ears.

Its unknown how Mario's eyes and moustache are floating but its probably due to him being a ghost with no head.

Mario likes being in the dark just to be more creepy when he's nearing the player.
