Well I realized I never stated what powers Nighto has, or specifically.

Well he has control over darkness and death (go wild with that) we all know that, but is there anything else?

Nighto is normally 8'4" but he isn't always. His name entail something, NIGHTo get it? He's stronger at Night but also, at certain points during the night he gets taller, at 12:00 pm he is 8'5", at 6:00 PM he 9', at 9:00 PM he's 10', at 11:00 he's 11' and at midnight, for 1 minute he's 12'8" and is 10x more powerful. (This isn't major and if in your book you wanna change it, that's cool)(also Nighto doesn't need to change size if he doesn't want to)

+ Lustskull height also wagers at a maximum of 14' at midnight. (Again not major)

DARK SEDUCTION:
He name kinda tells you, he can force anything to listen to him, unless they have a stronger will power than him.

TENDRILLS OF DARKNESS:
He solidifies darkness, turning into tendrills to immobilize something.

DISTRAUGHT STRIKE

he concentrates Death energy into his blade, it will repulse and explode when he swings it.

Well those are his main abilities, but not even close to all of them
