Zerrick had SS-grade cells, level 8 cells, so to say. His supernatural ability was more like Elliot's authority of life. He had control over space itself, and he could proudly proclaim himself the master of space.
After all, the level 8 cells that he had integrated with the very fiber of his being gave him the strongest supernatural power that allowed him to mend space manipulate it as he wished, and he could even go as far as to open a spatial tunnel to outer space or instantly teleport himself and everything and everyone he was in contact with at the time of teleportation to the desired location. Also, Elliot knew that he could pull himself into another dimension too.
So, Zerrick could really do what he was saying!
He eagerly looked at Elliot.
Under his gaze, Elliot coughed in embarrassment and stayed still on his spot.
