I have ideas of how to implement the latter three into the games via post game for Darkrai and Shaymin and mid-game for the Manaphy Egg.Seeing as how Arceus will probably be the final boss of PLA which will somehow be compatible with BDSP, that already makes me excited for the new games coming out this year/early 2022.
As for Manaphy/Phione, Darkrai and Shaymin, I still don’t know how they’ll be implemented into BDSP.
Manaphy Egg- You meet a Ranger around Pastoria City (either in the Great Marsh, the Pokémon Center or on one of the routes surrounding the city) who tells you a bit about Manaphy and you are entrusted with the Egg. It hatches and you can show the Ranger Manaphy who then gives you a hint about obtaining Phione.
Darkrai- After completing the Sailor’s son eternal nightmare quest, whenever you visit your house, your mom will tell you that a package had arrived for you. Inside is the key to the old motel in Canalave City and everything pretty much is the same except the dialogue when you land on Newmoon Island is a bit different. Darkrai is angry that you woke up its victim who was giving it the strength to defeat its rival Cresslia in battle.
Shaymin- This is different than the original games. Whenever you go to the White Rock, you’ll see Marley who explains what the Rock is and what it does. She then mentions how she would really like to see Shaymin and the Flower Paradise but doesn’t think she ever will. She then suggests that you leave a note of thanks on the Rock. Then a stray Shaymin wanders on screen and looks at the PC and Marley and Marley notes that it looks sad. She then says it seems that Shaymin wants to go ahead past the Rock but there is nowhere to go. Just then a glowing light suddenly appears and the Flower Path is opened. Marley suggests that you carry Shaymin and see where this path leads. It’s a long journey but on the way Marley talks with you and tells you more about why she is so interested in Shaymin and its myths. You get a couple of short cut scenes depicting Marley’s facial expressions and how happy Shaymin seems to be along the way. When you arrive at the Flower Paradise, there is a cutscene of dozens of Shaymin are happily runaround in both Formes. Some are walking among the flowers and sniffing them and some are taking a nap while others are frolicking the air in their Sky Formes. The Shaymin you were carrying Happily joins its friends and Marley says how amazing the place is. She then gives gratitude towards you for helping her see her dream. Shaymin then walks over to you and starts staring at you intensely. Marley then says that it seems to like you and wants to travel with you some more. She then suggests catching it which prompts a battle.
