I would just make myself a modern personification of Jesus Christ and save the world and humanity, by helping them with all the kindness and compassion I have to make the world more independent, liberating, responsible, and balanced with dignity, integrity, and unity by making perfect medicine to heal all diseases, tumors, and painful flaws, as well as making personal growth/potential boosting magitek so that everyone can never fail at anything they wish to do as a career ever again, and understand everything so they can never be afraid.

@Legendaryform2023 for me, it would be a small animal like a bird. I would also hide my powers but I would also reveal them in other worlds that I would travel to like in Dragon Ball, I would 100% reveal my power and not hide it. Well, only a portion of it at least

@Abdalla1234 I like the way you Think. And say, we’ll just give characters like the Saiyan’s complete 100% Mastery of their forms and make a Fusion + Fusion possible and etc. I’d hide my powers in my real world but in dragon ball I’m going all out, the grand priest can’t stop me.

WWYD? The first task is always the same: to find out the true nature of our world, its cosmic players, and reality itself. Can't go mucking about if your knowledge level is only human. You need a frame of reference. And ... I think most of us who wish for cosmic powers really just want a Personal Reality as a playground. Cosmic powers would be an awesome responsibility.

@Legendaryform2023 it would be fun going from planet to planet and just whooping everyone's ahh in a battle. Be it in a dual, a tournament, a war etc. If it comes to it, I won't even mind fighting Gods of Destruction and Angels. Even Zeno if he feels like it.

Like dude, YOUR LITERALLY THE TRUE OMNI KING. Speaking of this whole topic I’m bout to post one that’s almost based on this but a lil different. Hold up.

I'd use it to instantly send criminals to jail, expose and shut down corrupt businesses, and clean up the world of it's pollution.

First off omnipotent won't be too much it would be perfect secondary Omni manipulation is basically omnipotent

Don't know what would happen if I actually had it but first I would want to reveal myself to the world and my powers

I hate secrets

Then I would probably make my own multiverse and explore it and as it's god rule over it helping my creation grow

I wouldn't be happy with such a powerful ability. But how would I use it, then I shall play with the lives of all in a game of constant apocalypse.

-Give humans gender dimorphism of MUTOs, have males have functional retractable wings, whereas females are plus seven-feet-tall and build like Part 2 Joseph Joestar.

(Bum, zero male-on-female rape whining now)

-Give humans superhuman strength, durability, speed, agility, reflexes, acrobatics, limb regrowth and complete self-sustenance. In male's case, also a high-speed flying ability.

-Have actual life beyond the stars. No random-ass insignificant bacteria on some planet two galaxies away, actual sapient alien civilizations with super powers.

That's all I could think of at the moment.
