The Negative Man is an enemy in Mother 3, encountered exclusively in a cave in Argilla Pass. He is a yellow, rectangular creature that is always depressed and rarely attacks; even when he does attack, it does very little damage, dealing only 1 HP of damage even when getting a smash hit as a result of his low self-esteem. He will repeatedly make nihilistic statements in battle. He can always be found in the center of his cave and does not move from that spot.
- If Lucas and co. fight him for long enough, he says, "Life is but a moment, a meaningless grain of sand", which is a line from the lyrics of the Flying Man's theme.
- If he is fought for long enough, he says, "I'm nothing but a worthless protoplasm", referring to the Worthless Protoplasm enemy found in Winters in EarthBound.
- Oddly enough, despite being one of the weakest enemies in the game his theme is "Strong One". This was likely intended to be ironic.
- It is not impossible to lose to Negative Man. If you have everyone except one character dead, and the one character left with 1 or 2 HP, it is possible to lose. Another method is going to the Debug room , replacing Lucas, Duster, Kumatora and Boney with 4 NPCs, the battle will lose immediately.
