Plant Barrier

Plant Barrier (プラントバリア) is Plant Man's power, a barrier of flower petals that spins around Mega Man and protects him from certain attacks.

 * Gyro Man: Mega Man 2: The Power Fighters

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.
