The Super Smash Bros. Narrator (aka That Cool Guy) is an invisible guy who says random stuff in Super Smash Bros. and all related Shames. He works for Nintendo. Example: "3... 2... 1... Go!", "Failure!", "Game."
WHAT is he?
It is believed he is some sort of alien that came to Mushroom Kingdom for the sole purpose of narrating shames. Others say he is just Master Hand with a voice-changer. Yet others think he is actually Mario using his super-voice.
