Another concept worth mentioning are the core mechanics of Mega evolution. This entire gimmick revolves around how the synergy between pokemon and their trainers can unleash immense powers and thus make them stronger. A requirement for Mega evolution is a strong bond between a pokemon and its trainer though the games don’t take that premise too seriously, as you can Mega Evolve any pokemon you just caught. There’s also this motif of wishing. If you recall Hoenn’s lore, Rayquaza’s Mega evolution was the result of the ancient people’s wish to save them from great danger. That means Mega Evolution can be also described as some sort of interplay between a trainer’s wish (“My pokemon should exceed its powers”) and that of a pokemon (“I want to live up to my trainer’s expectations”). If we apply this to Key and Mega Stones, we can conclude:
>It’s the wish and strong bond of a trainer-pokemon-pair that causes Mega Evolution related stones to react.
