Yeah but like Dante said, it doesn't have a will of it's own or anything like that, it's just that Sirzechs doesn't have any control over his powers in that form.

Also the reason why Sirzechs can attained this level of strength is because of his magic talent from the Gremory. He combines his Power of Destruction and his magic talent. That's how Sirzechs could compress his POD in highly destructive orbs.
