Fixing and expanding the Pokédex

The Pokédex originally expanded the lore because of limitations in the hardware. Legends Arceus was the first game to expand on the Pokédex's functionality, but its research tasks are somewhat arbitrary. Here's my thoughts on a great Pokédex system:

1. Pokémon should display behaviors, which are then catalogued in the Pokédex. Things like behavior, temperament, predation, habitat, sociability, and unique behaviors.
2. The Pokédex should have a camera to capture pictures of behaviors. This will be used as the research tasks. The pictures for each task can be viewed later and replaced with new pictures (like Zelda's monster compendium).
3. The Pokédex will have expanded information, such as moves and abilities. This is filled out as you encounter the moves or by NPCs (gift or purchase). Pokémon will be able to attack the trainer with their 4 moves, which will automatically be recorded in the Dex.
4. Footprints will return from the gen 5 Pokédex. Pokémon can leave footprints on the ground, which can help with tracking Pokémon.
5. Certain Pokémon can migrate, appear at different times, have preferred weather, differently seasons (hibernation), and can be encountered while asleep if you're strategic. This is all shown in the Pokédex.
6. To complete the entry, you don't have to do every research task, but doing so increases the shiny rate and the chance of rare marks.

With these changes, Pokémon will feel more like a living and breathing world while adding a level of fun.
