Mario GameShark

Mario Game-Shark (abbreviated as MGS) is a Mario horrorbrew character/EXE created by @the_dark_lord5, on 16th October 2022. He was originally made as a reimagining of the original Mario.EXE, and as the star of a Triple Trouble remix, soon evolving into a fully fledged character. He is planned to star in his own FNF mod, along with his own creepypasta-esque story.

Overview
MGS is Mario's player code merged with the garbage data leftover in Super Mario Bros, or what we call the Minus World. He appears to be completely self aware of his own existence.

MGS, when first encountered, will appear identical to Mario. In some cases, he can appear to flicker, distort and gain purple-pink facial features.

When in his true form, he is much taller, around 2 times Mario's height. His eyes, hair and moustache appear to merge into one, though this can be interpreted as NES limitations. His hair appears to be much longer and unkempt, and his eyes are replaced by 2 glowing pupils. His most distinguishing feature are his purple streaks that seem to flicker and distort. This is the result of his garbage data makeup overflowing into his Mario data, corrupting his sprite.

Backstory
MGS was created by Adam Westforth sometime in early November, 1998. Adam was not knowledgeable on cheat devices, and borrowed his cousin's Nintendo 64 GameShark to try and use with his NES. Attempting to cheat at Super Mario Bros, Adam forcefully shoves the cart onto the Super Mario Bros cartridge, which very nearly broke the circuits inside. Miraculously, the game would still work.

Mostly.

Through Adam's actions, Mario's player code and leftover garbage code seemed to intertwine and create a sentient entity. This entity seemed to have malicious intent, as when the game was turned on, Mario appeared to talk to Adam. Shortly after, Adam would be found dead in front of the TV, with various electrical burns and cuts.

His parents, blaming the faulty NES, would dispose of the NES and its game, later found by a pawn shop owner. He would sell the NES and the game to one Sheila Garston, who would begin playing the game, only to be met with the same fate as Adam, sometime in late September 2003. Her family would return the NES to the pawn shop, only for the console to be bought again in 2004.

The newest owner would be Donovan Farthingstone, a nerd obsessed with Super Mario and all things Nintendo. He had a loving wife name Kara, and a 1 year old son named James. Unfortunately, he too would meet the same fate as those before him, his death occurring on 9th March, 2006. Kara would decide to lock the NES away as a keepsake, as she did not blame it for Donovan's death, rather, blaming the faulty attic lights.

Years later, in 2019, whilst Kara was away on a buisness trip concerning work, James decides to go explore the attic. He finds a plethora of old appliances and toys, but most exciting of all, an old dusty NES with a copy of Super Mario Bros.

James, excited, sets up the NES and turns the game on. He did notice something odd about the title screen, however.

Mario appeared to be looking at him, smiling.

Trivia

 * He has 3 total victims so far, with one being the father of the protagonist, James.
 * MGS would get along with most other Mario EXEs.
 * MGS converts whatever souls he collects into data and stores them in the garbage data, forever making them a part of the Minus World and himself.
 * MGS, whilst not having a true canon voice, would sound very much like Lou Albano's portrayal of Mario. This is due to MGS being created before Charles Martinet became the voice of Mario.
 * He isn't quite up to speed with most pop culture.
 * He hates Facebook, deeming it boring.
 * He appears to not like mustard.
 * In the NES, he speaks via text boxes, or DPCM voice clips that he makes himself. How he does this is unknown.
 * His Too Slow and You Can't Run forms shown in his Mario Mix are non-canon, only having his real form and disguised form.
