"Excellent! Access successful! Now, can you see me? ...Ah, it seems this is working! My name is Grand Oak. I'm a renowned Pokémon researcher! It's a pleasure to make your acquaintance. I'm the one who developed Pokémon HOME, which—as I'm sure you're aware—you're accessing right now. What a grand day to remember! Oh, but look at me getting carried away. I haven't even given you a chance to introduce yourself! Please, tell me your name."
"Ah... So your name is <player>! You see, my dream is to create an absolutely grand Pokédex by registering all the Pokémon that exist in the world! But if I'm being honest, I don't think I'm able to do it alone... And that's where you come in! Please, you must help me! You can fill the Pokédex by bringing Pokémon here to Pokémon HOME. Of course, I will do everything in my power to assist you as well! Pokémon HOME has some grand features that will help with gathering Pokémon! First and foremost, there's the trading functions! These let you trade Pokémon with users from all over the world! Additionally, you'll also be able to receive Pokémon as Mystery Gifts! What's more, you'll be able to see the rankings of all Trainers across the world who are enjoying Pokémon battles! Hah, I can see you're in awe of the grand features I've developed! ...What's that? You don't have a Pokémon? Well, in that case, I think I can give you one as a special gift! Choose the Pokémon you want!"
  • Upon selecting a starter
