Team GO Rocket's Cliff returns in April 2024 in Pokémon GO providing one of the toughest tests for Trainers in the game. Cliff has long been a thorn in Trainers side and once again returns with a mixed line-up of seven Pokémon in three waves. Cliff can easily overpower you if you aren't prepared, so you need to go into battle with a squad that is super-effective against his Pokémon.
