The Rulebreaker is an Aspect Lord who managed to break free from the others and transcend even Omnipotent^∞ power. He has far fewer limits than even the strongest Aspect Lords in The Barrelplex, seeing as he has very few equals, and even fewer superiors.
The Rulebreaker can completely shatter normal terms of logic, reaching levels of power that don't even exist, such as Omnipotent^∞^2, and achieving things that are beyond impossibility, such as there being only one of him in The Barrelplex. This incredible power far beyond all known laws of logic within The Barrelplex has made him a target for many powerful Aspect Lords seeking to remove all such 'imperfections' in what they believe to be the 'perfect system' of The Barrelplex.
The Rulebreaker now exists far beyond the powers of some Unthinkable and even the strongest Aspect Lords, holding such incredible strength he is notable even to forces such as The Infinite Madness, which he is currently working with. The Rulebreaker, however, does not in fact share the ideals of The Infinite Madness, but simply sees it as a means to an end in terms of erasing The Aspect Lords.
The origins of his rulebreaking abilities are unknown to himself, though they are suspected to be linked to the Eternal Defiance.
