Plant Barrier

Plant Barrier (プラントバリア) is Plant Man's special weapon. It is a barrier of condensed energy shaped like flower petals that spins around the user and protects him from some attacks.

In Mega Man 6, the shield vanishes when hit and Mega Man can't throw it. In the fighting games Mega Man: The Power Battle and Mega Man 2: The Power Fighters, the shield can hit several times before vanishing, and the user can throw the shield at enemies.

Capacity
In Mega Man 6, activating one Plant Barrier uses 4 weapon energy units. In Mega Man 6 and Mega Man: The Power Battle, it can be activated 7 times with a full weapon energy gauge. In Mega Man 2: The Power Fighters, it can be activated 4 times.

Trivia

 * Unlike the other shield weapons, the Plant Barrier does not protect Mega Man from the Robot Master that's weak to it. Tomahawk Man's feathers and Silver Tomahawk go right through it.
 * Unlike Skull Barrier, Plant Barrier won't vanish after hitting an invulnerable or shielded enemy. In fact, it will ignore them.
