Another question.

The trainers being the squishy, weak humans that they are, are they going to be subject to various environmental hazards and dangerous effects of Pokemon powers? For example, exploring a lava cave and dying from the extreme heat. Worse, what about Psychic 'mons using their mind-altering powers on the humans? It's been explicitly shown in the anime that these powers can indeed affect humans. What's stopping a player from, say, having a Malamar, and then mind controlling all of the other players in their sleeps when they aren't expecting it? The Dark One could use similar tactics to ambush and eliminate the humans, who are clearly the weakest links in their Pokemon teams.
