No, just very specific pikachu.
Or, well, to be more accurate, it’s pikachu who have been specially trained for shows, and even then, you need to have a pikachu with a certain temperament. It’s acting, in a sense: pikachu assume roles associated with their costumes, and in the process of focusing so much on their roles, they manage to develop abilities that fit their characters. In a way, it’s further proof that the pikachu line is more adaptable than scientists initially thought … or that pokémon as a whole are.
(Personally, though, I’m a bit envious. Think of how much more effective my costumes would be if I could develop the abilities of the pokémon I’m studying, just by focusing on assuming its character!)
Considering the fact that you’re working on a mega aerodactyl costume, I think I speak for everyone when I say it’s a relief you can’t. —LH
