Team GO Rocket

Team GO Rocket are organisation and the main antagonists in Pokémon GO. Based on the original Team Rocket, Team GO Rocket is comprised of:
 * grunts,
 * leaders
 * and Giovanni.

Game features
Members of Team GO Rocket, mostly grunts, happen to appear thanks to following game features.

PokéStops takeover
According to game's published media, Team Leaders and Professor Willow have observed Team GO Rocket members hanging out at discoloured PokéStops and it appears as they are after the PokéStops' resources.

Team GO Rocket grunts happen to takeover PokéStops. Such PokéStops have different appearance in the Map View:
 * when taken over PokéStop is out of range, their have darker colour scheme and the cube on the top tends to shake and twitch,
 * when such PokéStop is approached by a trainer, it turns it becomes black, the Team GO Rocket logo will appear over it and grunt appears next to the PokéStop.

After spinning such PokéStop's Photo Disc items are still given and grunt will appear in the Photo Disc view to challenge trainer to battle them. Player can leave the PokéStop or engage battle with such grunt.

The PokéStop will be invaded for 30 minutes at a time. After defeating the Grunt, the PokéStop returns to normal. All trainers see the same taken over PokéStops, but turning them normal is instanced for each player.


 * For more information on Team GO Rocket Grunts and finding them, see here: Team GO Rocket Grunts

PokéStops serving as hideouts for Team GO Rocket Leaders and Giovanni act differently from PokéStops taken over by grunts. Out of range they seem as regular PokéStops in the Map View.

After tracking down and approaching PokéStop being a hideout of either leaders or Giovanni, this PokéStop will act like approached PokéStop that was taken over by grunt &mdash; it also turns out black and team logo appears over it but with a leader or Giovanni standing next to it. However, only when appropriate Rocket Radar is equipped, the leader or Giovanni will show up next to approached PokéStop.

This feature is only available to Trainers who are Level 8 and above.

Balloon encounters

GO Snapshot Photobombs
Grunts were spotted in photobombs, while using GO Snapshot, during the Team GO Rocket Disruption event and the evening after attending Pokémon GO Fest 2019 events. Giovanni appeared as a photobomb at Yokohama Pokémon GO Fest 2019.

Special Research
There were several Special Research campaigns revolving around Team GO Rocket and features related to them. These are, these Special Research sets:
 * A Troubling Situation - Introduction to Team GO Rocket and Shadow Pokémon
 * Looming in the Shadows - Team GO Rocket Leaders Research in November 2019
 * A Challenging Development - Team GO Rocket Leaders Research in December 2019
 * The Take-Over Continues - Team GO Rocket Leaders Research in January 2020
 * A Professor’s Work is Never Done - Team GO Rocket Leaders Research in February 2020
 * The Shadowy Threat Grows - Team GO Rocket Leaders Research in March and April 2020

Battling Team GO Rocket members
Trainer can engage battle with any of Team GO Rocket members, after interacting with them or the PokéStop next to them &mdash; encountering grunt at taken over PokéStop or locating hideout of either leader or Giovanni.

Battling any Team GO Rocket members uses the same game mechanic as Trainer Battles with two significant differences:
 * Trainer's Pokémon after fought battle are not restored to full health automatically, therefore Trainer has to use Potions or Revives, like after battles in gyms and Raid Battles.
 * There is no specific battle league in these battles so Trainer does not have to choose one.

To engage battles with either Leaders or Giovanni, Trainer need appropriate Rocket Radar equipped.

Winning battles with any of Team GO Rocket members rewards Trainer with Stardust, specific items and gives them opportunity to catch a Shadow Pokémon in bonus Rescuing Shadow Pokémon Mission. Defeating Grunts and Leaders counts towards Hero medal while, defeating Giovanni counts towards Ultra Hero medal.


 * For more information on battling specific members of Team GO Rocket, see: Team GO Rocket Grunts, Team GO Rocket Leaders and Giovanni.

Rescuing Shadow Pokémon
Trainer can access Rescue Shadow Pokémon feature, after they successfully defeated any member of Team GO Rocket (including grunts, leaders and Giovanni) similarly to the Bonus Challenge in Raid Battles.

The Shadow Pokémon available for capture is usually the first one battled – in case of Grunts and Leaders, but there is also chance of catching the second one – only in case of Grunts and in case of defeating Giovanni – these is a chance of catching Shadow Legendary Pokémon which has 100% capture rate and can be different each month.

When attempting to capture Shadow Pokémon, they attack far more often than normal, making themselves especially hard to catch. A Nanab Berry help with this. Also, while Shadow Pokémon often have a deep orange or even red ring (even for common, low-level Pokémon), it seems to be misleading, as the capture rate is not as low as the capture circle implies.

Similar to Raid Battles, Premier Balls, will be used to capture left behind Shadow Pokémon. At least three Premier Balls are given after a victory, and the number of extra Premier Balls received (beyond the base number of two) is based on how many Trainer's Pokémon survived the battle and the ranks of the Hero and the Purifier medals.

Shadow Pokémon that are being captured after battle with Leaders can be shiny.

Shadow Pokémon
Shadow Pokémon are kind of Pokémon that can be acquired after a successful battle against any of Team GO Rocket members. According to the Professor Willow in game's published media, Shadow Pokémon are modified, strengthened Pokémon that suffer and Trainer should rescue and purify them in order to revert them to their regular state.

Shadow Pokémon cannot be traded away by the Trainer who rescued them unless they are purified first. Purified Pokémon can also become stronger and require less resources to power up.

Statement
Trainers…

For three years, we have been watching. The world of Pokémon GO is rife with unlimited resources. This privilege is wasted on Trainers like you who lack the vision to exploit this vast world of resources and Pokémon.

You walk around and spin your PokéStops like this some kind of game. You battle in your Gyms and rejoice when they change colors. You care for Pokémon as though they're something more than tools! What a waste of potential!

We've brought our Shadow Pokémon, strengthened to unimaginable levels that you could never reach through powering up alone. We're here to take over your PokéStops and steal from their unlimited supply of resources. Can't you see the beauty of our evil?

This is just the beginning. Your resources are our resources. Your Pokémon are our Pokémon. Your world is our world! You can't stop us. Professor Willow, Spark, Blanche, Candela, and most of all, you—stay out of our way!

We follow the villainous path of those before us—and we will succeed in finally bringing Giovanni's vision to the world!

If you insist on trying to disrupt our plans, we wil lmake you feel a world of pain!

—Team GO Rocket

Trivia

 * The possible reward Pokémon for the "Defeat a Team GO Rocket Grunt" Research Task (Ekans, Koffing, and Meowth) reference the Pokémon originally used by Team Rocket members Jessie and James in the Pokémon anime.
 * The game element was introduced in July, 2019. However, it was suspended one day later due to adjustment of Shadow Pokémon.
 * Team GO Rocket was released again on July, 2019.
 * Event Team GO Rocket Disruption was held to promote the introduction of Team GO Rocket.
 * If you do not have any space in your Pokémon storage, after defeating Team GO Rocket you would exit without encountering the Shadow Pokémon; however, the Grunt does not disappear, and after clearing out space you can simply tap the Grunt to go straight into the encounter without needing to defeat the Grunt again.
 * Capturing a Shadow Pokémon at a Pokéstop resets it; you can spin the photo disc to get items, capture the Shadow Pokémon and get items again even though 5 minutes have not passed.
 * The original Flying-type hint was "My bird Pokémon wants to battle with you!". It was changed due to some Flying-type Pokémon do not look like birds such as Zubat, Gyarados or Dragonite.
 * Previously, you are unable to use items while choosing your team without exiting the encounter entirely.
 * Before the introduction of Team GO Rocket Leaders, the hints of Electric- and Ghost-type could not be displayed. Normal dialog was used before the battle.
