Fan Casting Celestial in Avengers: Infinite

This Celestial has always been disgraced by other Celestials and power hungry. When the opportunity arises, he kills several of his fellow beings and takes their power. He begins to tear apart reality and the multiverse in search of the Infinity Stones, that will give him eternal power to overthrow his higher beings and the Beyonders. With all that he destroys, the Infinity Stones get further away from him and guide the Avengers to keep them out of his grasp. After the Avengers take the Stones, the Celestial launches several attacks on Earth. But when all the Avengers return with the Infinity Stones, he travels to Earth and faces the Avengers himself.
