Mega Mewtwo X is a part of the Uber tier of competitive battling. Thanks to the versatility of the other two Mewtwo forms, Mega Mewtwo X can surprise opponents with its presence and hammer them with its strong STAB attacks and a sky high 190 base Attack. Due to its high 130 base Speed, Mega Mewtwo X can act as a strong check to Extreme Killer Arceus with good defensive investment to tank a +2 Extreme Speed and retaliate with Low Kick. Mega Mewtwo X's overall coverage is relatively decent, as it can cover its bases with specific coverage moves like Earthquake and Ice Punch. Access to Taunt allows for Mega Mewtwo X to not be easily statused and force out walls that could threaten Mega Mewtwo X otherwise. However, it does take up a Mega slot that can be dedicated to another Pokémon with better overall type synergy or better offensive sweeping power. Mega Mewtwo X is also easily walled by some very common Pokémon, such as Mega Sableye, Giratina-O, and Ghost Arceus.
