The Reason people call it "Ultimate Grey Matter" is because fan of the show who have watched Ben 10 for a long time will know that Grey Matter is a Galvan but Newer fans of the Show will not know What a Galvan is/ What Grey Matters Kind is called. So calling it Ultimate Grey Matter is a simple solution to this problem.
