In the games, Mewtwo is consistently noted as being one of the strongest opponents, and has been described in "Pokémon Red" and "Blue" as being "the best Pokémon in the game", as well as "one of the rarest — and hardest to catch". Because of the character's multiple strengths and few weaknesses, it changes how players approach playing against each other, causing players to either develop strategies solely to defeat an opposing Mewtwo, or to prohibit its use when battling other players. IGN's staff bemoaned its exclusion from "Super Smash Bros. Brawl". A poll by IGN on whether the character was missed by others in "Brawl" shared a similar sentiment, though they also described it as one of "Super Smash Bros. Melee"s weakest characters. Professional "Super Smash Bros." player Jason "Mew2King" Zimmerman takes his handle from Mewtwo, although he uses other characters in competition. Authors Tracey West and Katherine Noll called Mewtwo the fifth best Legendary Pokémon and the sixth best Pokémon overall.
