Article on Bulbapedia Psystrike (move)

Psystrike (サイコブレイク, Psycho Break) is Mewtwo's Final Smash.


Mewtwo Mega Evolves into Mega Mewtwo Y and throws forward a large energy sphere which can trap multiple opponents. Those hit by the sphere are held still and receive a psychic blast, which deals 40% damage (or 29.4% via the Final Smash Meter) and massive knockback. It can KO middleweights from the center of Final Destination at around 50%. Aside from the Super Star, Psystrike ignores any form of invincibility.

Time is slowed down before Psystrike is fired and right before opponents get launched. This is one of the few ways to see screen KOs slowed down.

Mega Mewtwo Y is one of Mewtwo's two possible Mega Evolutions, which is achievable when it is holding a Mewtwonite Y. Unlike most Mega Evolutions (including Mega Mewtwo X), Mega Mewtwo Y is smaller than its normal form instead of being on-par or larger than its normal form. Although this is reflected in Mega Mewtwo Y's Defense statistic noticeably decreasing, the remainder of its stats gain tremendous increases. Mega Mewtwo Y was the first revealed Mega Evolution in the franchise.

Although the Mewtwo in the Super Smash Bros. series is primarily based on the Mewtwo from the first Pokémon movie, Mega Mewtwo Y debuted as an alternate form for a different Mewtwo from the sixteenth movie. The Mewtwo from the first movie has never been depicted using Psystrike in any media.

Psystrike is Mewtwo's signature move and among the strongest Psychic-type moves; it debuted in Generation V, and can be learned at level 100 or via Move Relearner. Due to essentially being a more powerful version of Psyshock, Psystrike uses the target's physical Defense stat when calculating damage in spite of being a special category move. Psystrike's depiction has changed since Generation V, originally attacking the foe with particles before using a large sphere; the depiction in Smash uses the latter. Since its inception, other older legendary Pokémon such as Groudon and Kyogre have received new signature moves, in this case for Omega Ruby and Alpha Sapphire.

  • Even though it's Mewtwo's signature move, Psystrike was introduced in Generation V, in which Mewtwo could not be obtained except by trade, Poké Transfer, or Nintendo events.
  • In Ultimate, Psystrike is completely unaffected by Spirits. This includes the "Final Smash ↑" skill, which is specifically intended to boost the power of Final Smashes.
  • Excluding Triple Finish's usage of three canonical moves and Max Malicious Moonsault taking most of its name from the Z-Move Malicious Moonsault, Psystrike and Volt Tackle are the only Final Smashes from the Pokémon series that have the names of actual moves from the series.
  • Although it is depicted in the Super Smash Bros. series as an energy sphere that targets the opponent's mind, Psystrike was originally depicted in the Pokémon series as a plethora of shards made out of energy that targeted the opponent's body. As of Generation VII, Psystrike's depiction in the Pokémon series heavily resembles its depiction in the Super Smash Bros. series, albeit with the energy sphere exploding on contact with the opponent's body, instead of targeting their mind.
