Superguard

The Superguard is a move used in Paper Mario: The Thousand-Year Door. It is the more advanced version of a Guard. It stops any attack from doing any damage at all, and any direct-contact moves will be returned to the attacker causing the enemy one damage. On indirect-attacks, the Superguard will simply negate all damage, with the exception of a Pokey's body segment throw attack which will send the body segment back to the Pokey and cause the same amount of damage the attack would've done to Mario or his partner. It will also block any status effects from an enemy attack. X-Yux's immobilizing ability can only be blocked by a Superguard.

Despite being incredibly useful it is even harder to execute than a Guard. A superguard can be done by pressing B right before contact (&#188; of a second). If done correctly, Mario or his partner will spin around and words will pop out next to him or her saying "Great!".

Trivia

 * The Superguard is very similar to the Pixl Barry's ability in Super Paper Mario as both require timing (though Barry's doesn't have to be very precise). Both deal damage to the opponent and protects the player from damage, and their animation is very similar (spinning in place).
