I’m afraid idiots are hard to hypnotizeMore like Brain Washing (literally had a lot of it).
The Three Genies (I think)
Any time Colress was on the screen, there was brainwashing
Literally an entire port town (and Pikachu yet again, I think) (minus Ash and TRio) was brainwashed by aliens
I think I'm missing a few more, but yeah, Brain Washing.
