>>50793915TPC has been reusing assets since the beginning of the 3ds era. That animation was never exclusive to them since other NPCs uses it thourgh SM/SWSH. Rei/Akari (depending on which one is the rival) uses an animation from Hop (not Lusamine/Hau's but one where he has the hand on his waist and with the other hand makes a gesture of explanation) but the most blatant one must be Zisu's battle intro that was taken from Hop's.
