As strong as others are, I'll pick Accelerator because I'm more familiarized with his level 5 ability.

Saitama is basic and simple, but the fact he can grow stronger through emotional moments or just because, he just one punch everyone, also he's literally me in a way, I choose him because of being relatable. I just want to experience the loneliness.

Bro I gotta get that Raphael bro. Just with its knowledge alone I could conquer earth then u add absorption replication and limitless adaptation powers ur just broken.

Rimuru is by far the best option. He litterly has Every ability so if you chose him you get the whole list.

@Retex I was waiting for someone bring up the Complete Arsenal argument, but no.

Don't use any of this wiki's definition literally when bringing up to discussions like these.

Rimuru doesn't have any feat beyond multiversal, so he isn't high-dimensional or anything.

Again, Rimuru doesn't actually have Complete Arsenal.

@RayanKraftBR

You should have at least mentioned that you just use LN Rimuru and not comp or WN.

That means he dosen't have Every ability yet but wtf do you mean Muliversal ? He has attacks beyond matimatical dimensions and attacks even beyond that additionally is able to destroy beings that trancend platonic concepts.

I just choose Sung Jin Woo because in the after story he gave his kid the Leveling system and his kid unlocked his own set of abilities

@Retex Obviously it isn't WB or comp.

If I included that, even Sung Jin Woo would be multiversal or something.

Actually, idk why but every remotely OP character has a WB version that makes them basically ROBs (Random Omnipotent Being). So nah, it's their canon version and the most known.

Rimuru, because he's cool

Giorno because life creation + causality reversal are a good enough for me.
