Going meta - game that broke the 4th wall - 1998

There is actually a computer game boss that was a reason of WTF players reaction due to breaking the 4th wall

Psycho Mantis from Metal Gear Solid (1998) - he established the psychic link with the player, getting invincible by that - you could not kill him as he predicts all possible moves and dodge your attacks. Furthermore, he spoke not with the game hero but with you directly - started controlling your pad and telling you about other games you already played ( by reading your memory card). The only way to beat him was to physically unplug the pad and connect it to the second PS port to break the psychic connection with the player.
