Pokémon GO will add, nine years later, a feature highly requested by fans of the main games
Bottle Caps and extreme training will arrive in Pokémon GO at the end of June 2025. This is all that is known.

It’s been a long time since the launch of Pokémon GO in that distant July 2016. Specifically, nine years. Since then, both Niantic and its new owners, Scopely, have been implementing all kinds of changes and novelties to the game, making it evolve in parallel to the main games. One of the novelties that will arrive very soon will be the bottle caps, which will allow upgrading the IVs of Pokémon to be able to turn them into three-star creatures.

Through a short teaser of just ten seconds, Pokémon GO has given clues about the upcoming arrival of the Bottle Cap, objects that serve to improve the individual values (IVs) of our Pokémon through the so-called extreme training or hyper training. The general reaction from players has been very positive, and there is great enthusiasm for their arrival.

In the main titles, including the Scarlet and Violet editions, extreme training thanks to the silver and gold badges unlocks the maximum potential of any Pokémon. By maximizing their individual values, the characteristics of any creature can be optimized, allowing them to be used unambiguously in the competitive scene.
This mechanic, which debuted in the Sun and Moon editions, makes it easier to obtain “perfect” Pokémon in the sense that, prior to its arrival, an essential part of creature training consisted of catching many of the same species to compare their individual values (attributes) and keeping the one with the best innate abilities. Ideally, the captured Pokémon should have maximum IVs.
However, since this is purely a matter of chance and a very tedious process, many players opted to simply generate Pokémon with perfect values using external applications such as PKHeX. Game Freak, in a conscious effort to avoid cheating in its games, has been introducing mechanics such as extreme training progressively to make life easier for trainers who want to take care of creatures legitimately, although this has not eradicated hackers completely.
The creators of Pokémon GO have not yet revealed the exact nature that their version of extreme training and Bottle Caps will have in their mobile game, but many fans welcome the implementation of this mechanic. This will allow “weak” Pokémon or shiny Pokémon - which normally have mediocre IVs - to be strengthened to the maximum, and will encourage connectivity between titles; Pokémon GO allows you to catch Pokémon that are complex to catch normally in the main installments, and thanks to Pokémon HOME, these can be carried over to other games such as Scarlet and Violet.
