The main purpose behind Jessie and James coming back to Pokemon GO is the Secrets of the Jungle event. This event will be running from Friday, October 1 to Sunday, October 10. It is unknown if Jessie and James will go away again once the event is over, but it’s still recommended to look for them as soon as possible.

As Jessie and James are technically Rocket Grunts, they will count toward any research task requiring Grunt defeats. This is especially helpful for players participating in the Search for Zarude special research tasks.

Jessie’s Pokemon - Scyther, Ekans, and Stantler

Jessie’s first Pokemon will be Scyther. This Pokemon is a dual Bug and Flying-type, making it weak to Rock, Flying, Fire, Electric, and Ice-type moves. It also resists damage from Bug, Fighting, Grass, and Ground-type moves. The best counters for the battle against it are:

It also resists damage from Fighting, Ground, and Grass-type moves. With this in mind, the best counters to use are:

James’s second Pokemon is his pure Poison-typed Koffing. It is weak to Ground and Psychic-type moves and resistant to Fighting, Poison, Bug, Grass, and Fairy-type moves. Because of this, it shares the same counters as Ekans. This is also especially helpful with how James’s last Pokemon is Grimer, another pure Poison-type. With this in mind, the counters for both Koffing and Grimer are:
