Nyx would be a Super Jump boss and have like 2 or 3 lives.
Spoiler
First few lives Nyx's rage gives him resistances to fire, bullets, and explosives along with less knockback taken.Last life when Nyx's rage would be Moonless Gown, where the damage is reflected back and insta-kill players like in actual P3. It would work similar to Wobbuffet rage but with a shorter duration period and more damage received to increase the rage meter.
