Disney once considered building a
park dedicated entirely to villains
called Dark Kingdom, which would
have featured Maleficent’s castle
as its iconic centerpiece.

Why do I get the feeling that anime Gym Leaders actually do have puzzles traps and disciples in their games just like in the games, but disassemble all of it when they hear Ash is coming out of pity?
Blain didn’t disassemble his traps when ash came and misty had to solve his riddle.
And to be fair, Ash never gets to quite a few of the gyms, he finds the leaders outside or someother bizarre circumstance happens (usually caused by team rocket)
