I would posit, Anikrahman1995, that BK&WK will learn their respective 140 BP Ice moves at level 100 as opposed to BS/BF (and yes, it's possible, because every in-game battle we've seen thus far with BK/WK has been an IR Flat battle). The most significant foil to my hypothesis could possibly be the necessity of said Ice moves at some point in the games' plot, but we'll have to wait to see.
I wish The Koffings had actual albums released, with music like this
. Then my life would be complete. <3
