>>49886967Shigeki Morimoto has added himself as a character in every game since gen 5.
In many of the games he is located in an area with a bunch of other characters who are also self inserts for staff members who worked on the game. This is meant to be an Easter egg for players and Morimoto usually gives you an item after you beat him, in Sw/Sh its the Oval Charm.
Again, it's not schizo bull shit, it's common knowledge to people who actually like and play Pokemon games.
