Eight Badges, 721 Pokémon, 100 TMs and 5 HMs, 30 Mega Stones, six legendaries and 596 items that are picked up, hidden or handed out: finishing X and Y at 100% takes organization. Here is the complete checklist, with checkboxes that your browser remembers from one visit to the next.
Items follow the order of the adventure: each location shows the walkthrough step where you find it. Items exclusive to one version carry a note; without a note, they exist in both.
Tick them off as you go: the counter for each location updates, and a finished location shows a checkmark. Checkboxes are saved in your browser, on this device.
