Lots of different views seem to come up on this matter and a lot of inconsistancies.
Are they literally tough as a galaxy at the core? Saitama is supposedly tough enough to onepunch them acording to the auther and there is the whole thing where wildbow talked about how endbringers can destroy the sun and the scene where behemoth withstood an energy weapon that could obliterate india yet scion dismantled behemoth with ease.
Ever read any Larry Niven shit? You know about scrith, or monomolecular hulls?
Jaxon Gutierrez
They're as durable as the plot demands.
Nathan Bennett
Saitama can obliterate half the universe with one punch, and that's only because he can only punch in one direction at a time.
Justin Walker
This, essentially. Wildbow getting into the mathematics of how durable they are is just a case of an author throwing around large numbers to make things sound impressive. Not that I'm going to hold it against him, that kind of thing happens all the time with fiction.
The best explanation is "very durable, getting exponentially moreso the closer you get to their core". Any detail beyond that is meaningless.
Caleb Jackson
Literally this considering their origin.
Julian Peterson
> just a case of an author throwing around large numbers to make things sound impressive. Not to mention that the big ass numbers they throw around usually isn't even close to big enough to actually be accurate.
Isaac Wright
Surface layer is equal durability to aluminum. The next layer is twice as strong as the previous. 222 layers surrounding a core.
Christian Walker
just like that one time he went on record saying that saitama could onepunch behemoth.
They can only be killed in fanfiction by: >Author fiat >Some bullshittery involving either clockblocker and/or fletchette >Some CYOA or self-insert with blatantly OP powers.
