PSI Magnet

PSI Magnet (Japanese:, Saimagunneto; called Psychic-Magnet in Super Smash Bros.) is a special attack that is performed by Ness and Lucas. It is done by pressing Down and B, and it absorbs certain projectile attacks (mostly energy type). Upon absorption, the attack replenishes the user's health equal to double to the damage that attack would deal. The user cannot be healed to a percent lower than zero, though. Interestingly, while Ness's PSI Magnet is formed centered around his body, Lucas' is formed centered around his outstretched hand, and thus the magnet doesn't fully cover the area behind him. However, Lucas will instantly turn around when hit from the back, which means the magnet essentially covers his whole body as well. It should be noted that a similar attack in Melee, Mr. Game & Watch's Oil Panic, allows the player to turn around while holding the absorber in place.

When used in the air, this move will cancel any vertical/falling momentum temporarily. This allows for this move to be used as a pseudo-SHFFL if used immediately after a jump, or a pseudo-wavedash if you activate the move at a downward diagonal angle. Lucas's version of this attack has a hitbox when released, which deals damage and has decent knockback, even enough to KO. Ness's version pushes enemies away when released which may help edge guard.

Trivia

 * In the original Super Smash Bros., a CPU would never use the Fire Flower against Ness because he could absorb the fire with PSI Magnet. They will throw it at him instead.  This also applies to Fox, who can deflect the fire with his Reflector.
 * The attack can be put to incredible use on the Corneria stage, by absorbing the Great Fox's lasers. However, if Ness or Lucas touch the cannons while they are "charging" it's almost guaranteed to KO them. Only the actual laser shots can be absorbed.
 * Neither Ness nor Lucas know PSI Magnet in their respective games.
 * In the Mother games, PSI Magnet did not absorb projectiles like how it does in Smash Bros.. Instead, it absorbed what was called PP (Psychic Points) which replenished the user's PP. The replenished PP could be used to use more PSI attacks.
