Entity 990

"I can’t believe we’re in the game, but it’s all black and white! - Markiplier, talking to two friend after entered a screen of a game"

Entity 990 is a error, psychic like the Wario Apparition, it is unknown from any games, as seen in 1998 in Kirby's Game then it got more scarier, before seeing him you better run, it looks like a forming-kirby that are dead, it got deleted from the game because it’s too dangerous, and may kill your console...
