Mewtwo Guide
In Red & Blue, Mewtwo is a Legendary Pokemon rated S-Tier. At 744 BST, it hits hard. It excels as a sweeper. Base 154 Special is where it shines.
Mega Evolution isn't available in Red & Blue, but Mewtwo does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Mewtwo hits 844 BST.
Mewtwo has no type weaknesses, making it hard to counter through typing alone. Focus on status moves, entry hazards, or raw neutral damage to take it down.
In Red & Blue, Mewtwo fills the sweeper role. It's a special attacker with base 154 Special. Base 130 Speed lets it outrun most of the field. And it's tanky enough to absorb a few hits.
In Red & Blue, the best way to handle Mewtwo: Priority moves (Mach Punch, Aqua Jet, Ice Shard) bypass its speed. Bulky walls that resist its STAB also shut it down.
Game Availability
