Team GO Rocket will continue to disrupt the daily routine of trainers in July 2025, bringing ongoing challenges in Pokémon GO. The three leaders - Arlo, Cliff and Sierra - are still active in the battlefield. If you want to finally face Giovanni, the leader of Team GO Rocket, defeating these three key figures is an indispensable step. Each leader will send out a very threatening lineup, including one of the most powerful Pokémon in Pokémon GO at the moment, so it must be fully prepared.

The three bosses have different Pokémon lineups, but they are all extremely challenging without exception. To successfully defeat them, you must have a clear understanding of their roster and form the most effective counterattack team . Each time you defeat Arlo, Cliff or Sierra, you will receive a series of rewards that motivate you to continue searching for them appearing in supply stations and rocket balloons this month. The only prerequisite for challenging them is that you must first defeat six Team GO Rocket soldiers.

Arlo, Cliff and Sierra lineups and counter-strategy

Use the best counter Pokémon to win

No matter which leader you challenge, the combat mechanism remains the same: each leader will send three of the seven candidates Pokémon to participate in the battle. Among them, the first Pokémon is fixed, while the second and third are randomly replaced in each battle.

Since June 2025, none of the three leaders, including Arlo, have changed their rosters, so if you have challenged them recently, there will be no new changes. Among them, Arlo is the hardest one of the three, because no matter what kind of Pokémon you choose, it is difficult to find a combination that can perfectly restrain all seven Pokémons. However, it is recommended to use a team composed of Tianlei Drum , Phoenix King and Gulado . These three Pokémons are powerful and can still cause considerable damage even if they cannot obtain perfect attribute restraint.

It is worth noting that all the Pokémon used by the boss are in the Shadow version , and their basic attributes and attack power have been improved.

When fighting against Cliff, using the Ice and Ground attributes as the starting lineup will bring huge advantages, especially when paired with dual-attribute skills. And Xerneas, the strongest fairy-type Pokémon in "Pokémon GO", can also play an excellent role, and has attribute advantages over Cliff's five Pokémons. Finally, Tianlei Drum is the third choice, and it can effectively suppress the remaining opponents with its electric skills.

Sierra's lineup is similar to Cliff, and there is also a Pokémon that can suppress his starter and sweep the entire game. As a double-attribute Pokémon on the water and ground, the giant swamp monster can flexibly use two attribute skills to quickly defeat Sierra's team. Jeraola and Banguilas are excellent backup options and can effectively deal with other members of her roster.

Rewards for defeating Arlo, Cliff and Sierra

Shadow Pokémon, eggs and rich props are waiting for you

No matter which leader you defeat, the rewards you receive are very similar. After a successful defeat, you will immediately encounter the shadow version of the boss's first Pokémon - namely Horsea, Gible or Trapinch, depending on who you are challenging.

In addition, you will also get a rare 12km red egg , provided that your hatched egg backpack has free space. You need to walk 12 kilometers to hatch it, but it may contain more rare Pokémons like Sandile, Pancham, etc. Finally, you will also randomly get some practical props, such as Max Revives and Max Potions , with specific drops varying from battle to battle.

Throughout July, three GO Rockets leaders Arlo, Cliff and Sierra in Pokémon GO will bring serious challenges. But as long as you use the correct Pokémon lineup to counter, you will not only win smoothly, but also receive generous rewards.
