I disconnected him at the waist on the figuarts, obviously, to get everything fitting nice. I trimmed the bottom afterwards with some small scissors, so the robe isn't so big, and I think it turned out pretty good.
I want to take what's left of the BS Kylo I have, now, and make a Knights of Ren custom out of him.
