Glitch Man

About Character
This character is the first boss you meet in the game. This character uses shockwaves to hit the player's screen which makes a cracking noise. This implies that the shockwave is actually hitting the screen.

Friends and Family
Glitch Man doesn't seem to have any friends or family, but since it seems like it is associated with Truth, so it may be a family member of Elizabeth. But it is definitely not canon.

Trivia
Although it may seem Glitch Man's "shockwaves" are non-canon, it actually is part of the game in the Game Over Menu.
