Shielding

Shielding is when you hold the shield button down, and a bubble of energy surrounds you. Shielding can block all attacks except grabs and Final Smashes. A way to solve this problem is to sidestep before the enemy grabs you. While you shield, the bubble shrinks. Some special moves can be considered as shielding, such as Lloyd's Guardian, Mega Man's Proto Shield, Pit's Mirror Shield, etc., but they can't be broken. If you Shield too much, or if the opponent hits it too much you will be in a condition called Shieldstun. This technique can also be used by Dark Blade and Super Mega Man.

Trivia

 * Both Yoshi and Megaman (in Demo v0.6) use their own unique shields (Yoshi hides in an egg, and Megaman used to protect himself by creating a force field).
