Nintendofan996 or Nintendofan998 (formerly Xboxfan996 or Xboxfan998) is an evil man who first appeared in Super Mario 64 Bloopers: Orbical Adventures, where he makes Mario choose between the orb and his brother, but his name is just "???". However, when he is brought back in Super Mario 64 Bloopers: smg3's plan to destory smg4 cause he felt like it, his name is revealed as Xboxfan996 or Xbox996 for short and possibly explode by the nuke. He also Revived and appears in the commercial Join the Evil Side. He is clearly called this because his color code is the exact opposite of X, and because he is doppelgänger of him. He is SMG3's best friend.
Nintendofan996's color code is (nearly) the exact opposite of Nintendofan997's.
Sky blue overalls
Dark Green cap, arms and shirt
Brown gloves (they, in fact, appear nearly orange, unlike X's shoes)
Normal skin (as Mario, Luigi and a lot of other guys)
