The most powerful Pokémon in the game is back.

The single most powerful Pokémon in Pokémon GO, Mega Rayquaza, is back in Elite Raids for a short time. On Saturday, June 29 at 12pm, 1pm, 5pm and 6pm Elite Raids will spawn Mega Rayquaza.

This is the first time that Mega Rayquaza has been in Raids since it debuted during Pokémon GO Fest last year. Trainers need a Meteorite to Mega Evolve Rayquaza, and there will be a free Timed Research during the event to get one.

Do not miss these Raids. Mega Rayquaza is a must have Pokémon in Pokémon GO. It is the single most powerful Pokémon in the game. As a Mega, it covers three-types for Candy and XP bonuses. Also, it's one of the coolest Pokémon in the game.

You'll need to be at your best to take this Pokémon down. So, here is everything you need to know before you take on Mega Rayquaza.

Best Mega Rayquaza counters in Pokémon GO:

Mega Rayquaza has a weakness to Dragon, Fairy and Rock-types. In addition, it has a 2x weakness to Ice-types. This makes Ice-type Pokémon a great choice to take on Mega Rayquaza.

Mega Rayquaza also has lot of resistances. It double resists Grass and Ground-types, as well as resisting Bug, Fire, Fighting and Water-types.

While this Mega Rayquaza Raid is one of the most difficult in Pokémon GO, the best Counter is a Pokémon that is readily avaliable. Mamoswine, evolving from Swinub, is a very easy Pokémon to get your hands on in Pokémon GO. Grab a few Mamoswines and you're set for this Raid.

Powerful Pokémon like Shadow Mewtwo have also been avaliable in recent months. However, the best moves for Shadow Mewtwo both require an Elite Charged TM. Be careful not to get rid of Psystrike or Shadow Ball for Ice Beam, as this will be expensive to replace.

There are some good Dragon-types, including Mega Rayquaza if you already have one, to take on this Raid in Pokémon GO. Although don't forget that all Dragon-types are weak to fellow Dragon-types. So, be warned that you could get through a lot of Pokémon if your team is mostly Dragon-types for this Raid.
