>>24919184Basically the extra style completely changes how the base puppet works.
So Raiko went from a bulky but slow(ish in A) pivot in her P and A stances to out-and-out wall in her E stance with good speed but unusably bad offenses for instance.
Rika went from glass cannon with poor speed to Aegislash. Sukuna went from slow focus killing machine to a glass cannon. Marisa went from blazing fast sweeper to slow and bulky. ShinkiE finally focuses enough in stats to really take advantage of her BST 600 and gets no weaknesses, but has no usable STAB or any resistances to compensate.
And the typing is usually changed at least somewhat, if not entirely.
