I've dleved into that a bit in my one shots. One time I had Suicune at the scene where Raikou had been captured earlier, and she demands the Pokemon of the forest to tell her what happened, but most of them are too afraid to speak. Other than that, I've had them as quite oblivious to ordinary Pokemon most of the time. (But then again, it all depends on which Legendary is involved.)Qne quick question for my next fic: What of their attitude to normal, trainerless pokemon? Wild pokemon that spot them and go over for a chat or something?
