I think him literally being destroyed by antimatter will stop him. Also, from the credits of Space Time, you learn that the smaller the animal with antimatter cells, the less stable their cells and therefore not only a higher chance of exploding, but also a larger radius. Korosensei's blast might have been half the size of the rat's.
