I recently managed to unlock the battle against the Fare Prince, courtesy of a team of ubers, and I'm slightly intrigued by his post-match speech, something like "It's not about finding your place, it's about making a place for yourself. I will make my own place... the next generation..."
Any theories as to what he means? Could it possibly be a foreshadowing of the next generation of core series games? It kinda makes sense to hide it in a secret battle that's only accessible after the Delta.
Well, this might be just Gamefreak poking fun at us all.
It's like how in the battle Maison in Pokemon X/Y, there is a woman who says "I come from the future."
We might not see some lore in the next gen saying something like "once upon a time there was this guy who had a philosophy and made the region the end" but I must say, mysterious.
