It's likely that this is King Crimson's true form.

Boss usually only unleashes a part of it.

Those arms are King Crimson's.

Are you sure?

I can tell just by looking. After all, I've seen the KinCri Punch enough first hand—

done to Squalo, that is.

That means... It was definitely Boss? I don't believe there's any Stand out there that has the power to control King Crimson.

Well, maybe not.

There's no doubt that this is King Crimson.

But it's possible that the one controlling your Zipper Man was not Boss himself.

It's actually Sticky Fingers but go on.
