2401

Biography
During the creation of the well-loved game, Super Mario 64, Nintendo workers tried to add Luigi in as a playable character you can unlock at the end of the game, but his code ended up becoming distorted and corrupted to the point they had to hide it into a locked folder somewhere deep in the game's files in order to protect the game from getting destroyed. They did, however, add a little fountain in place fo where Luigi was supposed to be found with L is Real 2401 written on a plaque.

24 years after the release of the game, someone hacked into the's files and discovered the locked folder. He unlocked the folder and immediately went into a fatal seizure. The witnesses reported that a Luigi with an elongated mouth was pounding on the screen while the words "Help him" played repetitively in Morse code.

After being released from his prison, 2401 had become unlocked on all copies of Mario 64. People who entered the garden and walked towards the fountain would see 2401's face and neck emerge from under the water and he would let out a cheerful chirp. Any players that run away from him end up being placed in a room they cannot excape from and forced to play games with him. Most of these games are pretty easy to win, and he will let you go after a while and continue playing

Players who try to attack him end up getting shocked by their controllers, then voltage increasing at every attack until it shocks them to the point their brains fry.

2401 doesn't want to hurt anyone, he's actually quite playful, but he is unable to handle violence and doesn't realize his strength.

Abilities
Elongation, shrinking, manipulate the area around him, manipulate sound, electrocution

Weaknesses
He has the mentality of a small child and wants to do nothing but play, he also becomes very upset with himself when he hurts someone and will hit himself in the head until he goes unconscious
