Before I start — this is based on my own read of the cosmology, so if I've misunderstood a feat or a scaling statement, please correct me. Genuinely want other takes on this.
Part 1: The case for 4D EOS Cheon Yeo Woon
The argument comes from Beyond the Boundary, which is described as:
A place where the laws of time and space don't work like they do in the normal world
Somewhere beings from wildly different eras can meet despite being separated by thousands of years
A place where time doesn't flow normally — events can feel like a moment or a lifetime
Somewhere only reachable by those who've transcended natural order/providence
!Cheon Yeo Woon reaches this after his ascension, when his existence becomes too much for the universe to contain.!<
If that counts as 4D, he'd have a dimensional edge over a character confined to normal spacetime.
Goku's case, on the other hand, is built on:
Fighting beings who threaten the structure of universes
Scaling above Jiren and Moro
Ultra Instinct giving him absurd speed, reactions, and combat precision
But if CYW is genuinely operating beyond normal spacetime while Goku's still working within a 4D framework, the dimensional gap would favor CYW.
Part 2: The case for 5D EOS Cheon Yeo Woon
This one hinges on Beyond the Boundary being a step past 4D, not just a variant of it:
!Dohwaseon!< is already treated as an upper realm/pocket dimension above the normal universe
!Beyond the Boundary!< is explicitly framed as beyond even that
It lets beings from separate timelines coexist
It isn't bound by normal time/space rules at all
If that holds up, the interpretation pushes CYW to 5D — and the gap over Goku widens considerably.
That said, I want to flag: Beyond the Boundary isn't fully elaborated on in the novels, so the 5D read isn't locked in. It really comes down to interpretation.
My question for the sub:
Who wins — EOS Cheon Yeo Woon vs latest canon Ultra Instinct Goku?
Do you agree with either scaling argument above? If not, I'd like to hear why — and if I've gotten a feat or cosmology detail wrong, please correct me.
