1. A very self-reliant person, kinda like an Alpha except higher.
2. Sigma from the Mega Man X series, a funny bald Maverick that's so stubborn to eliminate humanity to the point where he managed to come back from death more than 7 times.
1. "Oh wow, Henry is such a Sigma male! He never gives in to peer pressure!"
2. Person 1: "Oh wow, he's such a Sigma male!"
Person 2 : "Haha, you mean Sigma from Mega Man X? He's so badass!"

a mysterious place that few dexheads have actually been to, but all seek after. It's the quasi-quivalent to a k-hole with ketamine, but apperantly much harder to achieve.

Much debate resolves around sigma and the existance of a fourth plateau, or if sigma is 4p only in a different setting or if it's a different plateau all together .. or even if it's a plateau at all.
Yeah, I hear sigma is pretty strange, but as far as I can tell, the third just keeps going forever.
