which killer is the most sigma male among them

[Dr. Necro]

Not a beta, not an alpha but a true sigma male. Doesn't need perks, always on the grind.
rule #24: always mori survivors
rule #762: ignore survivors; work on challenges to get PAID.
rule #321: facecamp to show superiority

So, which is it?

[Zheppon]

Bubba

[Replicant Six]

Don't forget rule 34

[Kowalski_]

pyramid head fits perfectly with the rules you put:
- he has a mori built into his power
- doesnt bother hooking survivors
- extremely good at facecamping because of double hit mechanic with his power
ass might be too big to be sigma though, it brings a lot of attention

[Hand's Hermit Permit]

Trapper. Doesn't need to hit survivors at all. Lets survivors wreck themselves. Outsmarts virgin survivors and puts them on the virgin hooks. Gets called D-tier killer, and doesn't give a ♥♥♥♥ about it.
