What is obscure/interesting events or overall knowledge you know of Masters?

Kind of like a iceberg-like topic post, just anything interesting that has happened in the span of the game, could be one-time events, glitches, really anything someone might find interesting to know.

I remember you had to unlock the moves of characters or when sync orbs were earned through using a sync move once per battle?
