@mangafanVT: I'll give you feats of Eldergod demonbane, but since it's from a PSP game i can't give you scans..
His stare warped reality so hard that It called upon infinite Demonbanes, Existing and non existing from every plane/dimension/universe/point in time/dream etc.. One of those demonbanes also brought an infinite army with him.. All this demonbanes shoved Lemuria Impact (an attack with the power of infinity) and shoved it to Clockwerk Phantom.. The energy realeased from this attack created and destroyed an infinitude of multiverses in an instant.. (Eldergod Demonbane)
But i think his best feat is that he sealed the omnipotent creator of infinite multiverses and recreated every single one of them (Eldergod) This is why some say that Eldergod demonbane is the answer to the question "Could god create something so heavy that he himself cannot lift?"
Mars demonbane (weaker demonbane than eldergod) grew so big that the universe he's in popped and grew even bigger until he could look down on infinite demonbanes fighting from infinite multiverses at once..
BTW, his normal slash could create and destroy multiverses and rip through space time, can also destroy dimensions.. his fight with Liber regis literally created and destroyed countless universes, dimensions and planes with each slash.. (Mars demonbane)
