Pretty powerful. They would have twins named, Totality and Embodiment. Totality would have supreme reality manipulation powers and would have the power to ignite or extinguish stars with a mere thought. Embodiment would have the power to absorb all light energy and in essence would be the most powerful and sentient black hole in existence. He would also have limited reality bending. Both are immortal and rank just beneath the abstract beings. Both have awesomely powerful telepathy and can read every thought in the universe while engaging in battle. They can travel at an undetermined amount of times greater than light-speed. With their respective mights they could destroy a fully powered Galactus, 2 average Celestials or a full powered Franklin Richards.
