Super-Block Meter

Unreleased ​Super Block Meter  is a gimmick in the game Plants vs. Zombies Heroes. When either the plant of zombie hero gets hurt, a meter surrounding the health of the hero glows green for plants and purple for zombies. When it is fully charged, the hero will block the attack that activated the block and the hero will receive a superpower that can be used for free immediately or saved for later. Truestrike plants/zombies do not affect this.
