Since this battle has been toyed around with, a what-if scenario. Both brothers end up crossing paths with one another and using combat feats, they must beat the other to submission to drive them away.

Who would win in this battle?

vs

Bump, anyone?

Team Mythos. Nyarla's avatars casually transcend the concept of dimensions in Cthulhu Mythos and Yog-Sothoth is immeasurably stronger than Nyarla and nothing short of Azathoth can hope to defeat it.

HPL outergods win imo. Yog is basically azathoth's stand in and nyal cant be killed cause hes linked to azza.

Bumping. Any others? Another discussion said Michael and Lucifer wins with ease, but I'm not quite sure about that since the general consensus here is Yog and Nyarla win.

Lucifer and Michael win in a huge stomp. Yog Sothoth is omnipresent within Lovecraft's universe. But that's it. He's not omnipotent and neither is Nya. Meanwhile Lucifer and Michael together are basically omnipotent(Creating DC and all. Michael=infinite power, Lucifer=infinite shaping of Michael's power). Individually they are both "nigh-omnipotent" and omniscient. *Having infinite power and the ability to do literally anything with said power defines omnipotence).

Feat wise Lucifer and Michael individually will win 100% of the time; together it's a stomp. Hierarchy wise either Lucifer or Michael individually are also beyond both Yog and Nya. Lucifer/Michael are multiversal, Yog is merely universal and Nya is far below Yog in implied power(They barely have feats)
