In PM:TTYD, just as an enemy's attacks are about to hit, press B and you'll take no damage and deliver 1 damage to enemies who used contact attacks.
I've been able to superguard Goombas, Koopas, Paragoombas, Paratroopas, Craws, Puffs, Clefts, Dayzees, Swoopers, Rawk Hawk, X-Nauts, Lord Crump, Yuxes, and Doopliss with no problem. However, I can't superguard a Wizzerd's tickle.
