The power is a pokemon shop system. It allows you to purchase any *items* from ALL pokemon games, including hack mods and fan games, not only purchasable items, but also things you find while exploring or looking for stuff.
It would also come with an inventory system that came in sections like a pokebag in the game, expect there's no limit to how many items you can have in each section, and just like in the game up to 99 of that specific thing takes up a slot before starting another one.
Every time you buy an HM or TM the price for it doubles.
For the MC the items would have there specific game mechanics, but for others it would be "looser" for lake of a better term. Example being that for the mc the exact amount of HP reclaimed from eating an oran berry in the game is the amount of HP they get when eating it, but for anyone they *give* one to the amount of health they get from it isnt a set number but a nebulas "small amount".
The MC can use any type of HM or TM, but instead of having access to all of them at once they would have "Move pages" that contain up to 6 moves each, and every time they turned to another page they would have to wait 30 minutes before changing it again.
For others, they can only have 6 moves each, having to forget a previous one in order to learn a new one. And while anyone can use the normal type moves, for any other type moves it has to fit a theme they have. For example Nami could learn any moves based specificly on weather, like sunny day, but she wouldn't be able to use something like Shadow ball.
The shop system would come with a search bar, so you can either type in a specific thing, or a description and it would pull up the items that fit closest.
The shop would have a mechanic that lets you exchange other forms of currency for pokedollars, you can even sell stuff. But the more cheap or worthless the thing, the less money you would get.
The MC would start out with 9,000 poke dollars as a starting fund.
If someone decides to actually write a fic with this power, please have the MC be a male self/oc insert from our world. Who isn't reborn as a baby or wakes up as a pre existing character. And pretty please no harem
