If you were to have one Pokemon to be brought here in the real world, what would it be? (in terms of usefulness in real life, battling, and other mortal stuff)

Just one?  Hmm.  Well, I dimly recall someone asked me to bring an entire team into the real world once, and I honestly have trouble going past one of the Pokémon I picked then – Claydol.  The combination of Ground- and Psychic-type abilities means it could be taught to move the earth subtly, not just as part of an attack form, and it could sense things beneath the ground without having to dig them up.  I’m an archaeologist in real life; with enough training to refine them, powers like that would be a godsend!  Claydol’s no slouch in battle either, if need be, and it can even Teleport you from place to place.
