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. Plus any direct-contact moves will be returned to the attacker causing the enemy 1 damage. On indirect-attacks, the Superguard will simply negate all damage, with the exception of a Pokey's throw attack which will give it 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.
There is one catch, however. It is extremely hard to time, even harder than a Guard. This can be done by pressing B right before contact (¼ 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!".
