When the Transforming Warrior tag was first introduced, I thought that as a major villain tag, because Frieza, Cell, and Buu all had transformations. It could have been the tag to rival the Saiyans as the main villains of each arc, but I found that Cell does not have that tag. The tag is only exclusive to Frieza, Frost, Zarbon, and Cooler. What is the pattern of the tag? Because it would be cool to see these villains fight together.
