since he is the most powerful character in the universe, representing all the elements, yin and yang, all the elements, and all the other 'Otherworldly stuff' I'd just try to have a simple test if an OC's might can even compare to the immense power of the cube! he has the most unique power, he can shapeshift into anything, that means he can shapeshift into himself, causing a breakdown of the whole universe. to prevent him from doing this, I will set only one rule! No doing Universe breaking stuff, like fractals, or breaking the fourth wall.
