Team Rocket Boss Giovanni Lineup & Counters (June 2025)

Fighting And Ground Types Key

Compared to his line-up last month Giovanni has only made one change for June 2025. Despite the new in-game Team GO Rocket-based event, he will always use the same first four Pokémon as before. This means every time you challenge him he will still start with his trusted ally, Normal-type Pokémon Persian. His second wave of Pokémon also remains the same. It will be chosen at random out of Poison- and Ground-type Nidoking, Normal-type Kangaskhan or Rock- and Ground-type Rhyperior.

However, the big change for June 2025 is his final Pokémon will now always be Legendary Dragon- and Steel-type Dialga. Dialga is one of the strongest Pokémon for the Master League Cup in PvP matches.

Despite his change in final Pokémon, you can use similar counters to previous months against Giovanni this month. You want to select a team that between them is super-effective against all of his five potential Pokémon. Fighting-types are key to this battle, and you should lead with one every time, as it will be super-effective against Giovanni's opener Persian. There are a host of strong Fighting-type attackers in Pokémon GO, but two of the best are Machamp and Lucario.

It is possible that Giovanni's team could be made up of three Pokémon that are all weak to Fighting-type attacks. Out of his five possible Pokémon, only Nidoking is not weak against them.

You can also use a second Fighting-type Pokémon in your team, as Kangaskhan, Rhyperior and Dialga are also weak against their attacks. However, for a final Pokémon, a Ground-type is a great option. It is super-effective against the only one of Giovanni's Pokémon that isn't weak to Fighting-type attacks, Nidoking, but also has an advantage against Dialga. Using this makeup of Pokémon types mean that all three are super-effective against Giovanni's final Pokémon, making it much easier to defeat. The best option for a Ground-type is Legendary Gen 3 Pokémon Groudon.
