Here its stated again that B13 was going to destroy entire Continuum.
What's even crazier that it was only a small part of his power and he was doing it across omni-temporally.
He was an abstract level being even before he was powered by Imperiex power, capable of destroying entire timelines hence the name "Ravager of Timelines."
Yet, Superman gets beaten by some two trick ponies like Worthies. Never change KMC.
