This was something interesting i noticed a few days ago.
While i was playing through the arcade mode of Third Strike with Sean, i noticed that my sub-boss (Ken) was wearing his HK color outfit (the white Gi) instead of his default LP color (red Gi).
Obviously since i lost the match, i decided to switch to another character (Elena) and i got to fight her sub-boss, Makoto in the black Gi (also her HK color outfit) instead of her default white/yellow.
I experimented further and intentionally lost so i can switch characters. This time i selected Yun and fought Yang (in his HK purple color outfit).
So yeah, somehow the game decides to switch the colors of the sub-bosses to their HK color instead of the LP color. I’m just curious as to what triggers this (maybe it was the amount of continues i used) and if anyone else also noticed this quite possibly useless observation.
