>>25289485-Nintendo costumes.
-Headgear other than hats
-Pokemon being compatible with other Pokemon's Mega Stones (Venusaur using Blastoise's Mega Stone, Mewtwo using Lucario's Mega Stone and Lucario using Mewtwo's X Stone, etc.,)
-Type chart damage rebalance (Some strengths are nerfed from 2x damage is now 1.25x or 1.5x for some, some NVE damage is buffed from 0.5x damage to 0.25x or 0.125x) to reduce jobber Pokemon. Weakness Policy and Assault Vest stays the same.
-6 moves per Pokemon now or at least 2 reserve slots for HMs if those have to come back.
-No Ash Greninja shit, but some Pokemon can probably have "Bonding Formes" where specific Pokemon unlock powerful new formes if they get along with each other, except not stringent with gender requirements like Breeding (i.e. Bisharp and Accelgor, Zangoose and Seviper, Snorlax and Slaking, Infernape and Emboar etc.,)
-Quests, not achievements like the BW2 system, I mean stuff like getting a lady a Blissey for 20 Max Elixirs or clearing out an area full of hordes to get a costume set you can't find in stores. Would be nice to see maingames have guilds for this stuff, it provides incentive to explore.
-Have the Stadium or PBR Announcer return if there's contests again-Hair color options are not limited to "realistic" hues.
-Ridable Pokemon are an alternative to bikes rather than a designated area and don't require an HM to traverse certain parts. Some can even JUMP UP LEDGES
-Bring back Pokestar but have like dynamic camera and shit.
-Zelda-esque grunts and yelps.
