Mewtwo

The king of Pokemon GO: Mewtwo is here. It's stats are strong enough that it once persuaded trainers to take off work and pursue EX eligible gyms for a chance at capturing the Genetic Pokemon.

Mewtwo sits solidly among the highly ranked legandary Pokemon. Mewtwo was the first Pokemon to break the 4k CP threshold and earning itself a 9% nerf to all stats. Despite this, Mewtwo boasts the largest attack stat in the game before Deoxys and the largest bulk among any Psychic types.

Mewtwo has many claims with the highest Psychic-type DPS now and quite possibly for all-time thanks to Psystrike, hitting insane damage levels without breaking a sweat. Additionally, Shadow Ball Mewtwo provides a great 2-bar generalist Charge Move, placing it as a top raid counter even if its Quick Move is resisted

Mewtwo's introduction to regular tier 5 raids (as what is essentially a tier 6 raid) added 3 new elemental charge moves to Mewtwo's repertoire, furthering its utility and type-coverage. Flamethrower, Ice Beam, and Thunderbolt + Mewtwo's high attack stat give the Psychic-type Pokemon the ability to act as a de facto Fire, Ice, or Electric type.

Mewtwo's return in September 2019 gave it access to its signature attack, Psystrike. While this move sat unused and with outright bad stats deep in the game's file for years for years, just barely beating out Psychic in simulations, a buff prior to release has given Mewtwo a gigantic lead above and beyond its fellow Psychic types and allowed it to re-claim its throne as king.

Focus Blast also puts up a reasonable Fighting-type impression with higher bulk and better defensive coverage for knocking down Normal-types like Blissey and others commonly found in gyms.

For its continued use and versatility, Mewtwo tops our rankings and remains a great investment.
