It's pretty straightforward really. Mc has the power of a Trillion Exploding stars.
His sentry powers alone is enough to put him in top 10. With nihility unleashed, he can grow upto same level as One above all, even surpass him once he gets full control.
He is super OP from the start.
Strength, Speed , Endurance, Regeneration, Energy projection, reality manipulation and mental powers are the key one's.
He can literally mind break people hentai style, He won't do it, but let's just say he didn't choose tentacles, yet got it anyway.
Read after Chapter 10
His nihility essence has become trapped in his void, it'll act as a seal to suppress the Nothingness. Kinda like perfect jinchuriki, minus the bijuu.
He can't fully use his powers without destroying a good chunk of the universe, so at first, he will have to ealk on eggshells. It'll change soon though.
Also, the reason I went in depth with the dark stuff that happened to Mc is, after going through it all, he can easily tune out the Nihity within him, unlike Original Sentry who could barely utilize his powers.
It will also give you guys a simple thing, clarity, that whatever you are going through currently , you are still in a better place than many others, that it could get way worse. We should never take this small privileges for granted . We are living in a pretty messed up world right now after all.
Anyways, there will be still some conflicts of interest, and I can't really do much about it. There are some interesting multiverse themed fanfics here. But this story will be far different then the usual multiverse exploration.
I have already set up 3 universes , first one being Earth 2149, the real Zombie verse, not that cute what if version. There will be many interesting verses that have never been seen here.
So get your nerd gear ready weebs. You are in for a ride.
