Notes:

Garchomp, Scizor and Bisharp are obvious for Senketsu, scissor blade and the seijin form, I chose Gyarados for Ryuko's rage, Skarmory is Shippu and Gogoat is the biker aspect of Ryuko.
Might do one for Satsuki, though the only Pokemon I can think of are a Shiny Bisharp and Aegislash. Any suggestions?
