Notes:

The overall Steel type are suppose to represent her Iron resolve. With Shiny Bisharp representing Junketsu and Mawile with its Intimidate ability which Satsuki can inflict. With Ryuko's Bisharp not having now of that thanks to Defiant.
Haxorus is the Dragon of Kiryuin. And I chose it because it more of the normal badass Dragon in the franchise compare to Ryuko's pseudo-legendary Garchomp.
Absol is pretty much her Bakuzan.
And Volcarona is that shiny light that she always has.

Next would either be B!tch mom or Mako. Any suggestion for B!tch mom?
