The Pokémon Bank is finally compatible with Pokémon Sun and Moon, and it does a nice job beefing up Sun and Moon's post-game. But there's more to said post-game than just slaughtering rivals with old favorites who've been with you since childhood.
On the Pokémon subreddit, a redditor named ronnknee instructs fellow trainers on how to activate a peculiar cutscene involving an old man standing alone in the Haina Desert. You can only trigger the scene by showing the man a Solrock or a Lunatone, neither of which is native to Alola. You must bring them into the tropical region using the Pokémon Bank.
When you show either of the cosmic Pokémon to the old man, he suddenly "remembers everything," and says the "star pulses" bestowed upon him 30 years ago are still safe because they were entrusted with a group of "wonderful men." He then gives you a Moonstone and teleports off into space like Poochie being called back to his home planet.
The whole thing is pretty weird, but the Pokémon subreddit is pretty confident the spaceman is connected to the origins of Mr Bonding – a man who grants you O-Powers in Pokémon X and Y (he has older counterparts in Pokémon Omega Ruby and Alpha Sapphire).
But there's also a strong belief this cutscene is meant to hint at the existence of Pokémon Stars, the rumored follow-up to Pokémon Sun and Moon for the Nintendo Switch. We didn't see or hear a peep about Pokémon Stars at the Nintendo Switch event on January 13, but it's not hard to imagine Nintendo plans to reveal the game via a dedicated Nintendo Direct presentation (if Stars occupies our plane of existence, of course. Let's hope it does).
A note: Pokémon fans accessed the Haina Desert scene via hacking some time ago, but now anyone can see it legitimately with a little help from the Pokémon Bank. Here's how to import your favorite Pokémon into Pokémon Sun and Moon.
