Non canon multiverse ender form can happen whenever Hokashi wants to but canon Hokashi's multiverse ender form can only happen when either the crystal of creation is near to or breaks or when he gets the crystal of destruction

I think Edgy would be able to beat him with either of those separately, but he'd have a REALLY hard time.
Although if he had both Edgy would lose.
Hokashi is at his max. In his multiverse ender form he can just push attacks away with his fingers and can just nullify any attacks coming his way. If Edgy wanted to beat him he'd have to really try
