Hero Plants were a game mechanic and variation of plants that are only seen in Plants vs. Zombies: Journey to the West. They acted the same as their normal counterparts (except Iron Man Nut) that can be moved by the player anywhere at any time. Once the Hero Plant itself is upgraded to a specific level, they would also have different special abilities and a special skill that would activate automatically once charged, similar to the anger and Plant Food system in Plants vs. Zombies: All Stars. However, the player could only use one Hero Plant in each level, and the Hero Plant would appear on the player's lawn immediately once the level started. When the Hero Plant was eaten, it could no longer be planted again until the level ended.
Each Hero Plant could be leveled up by earning experience when being used in levels. By each time it leveled up, the plant would gain skill points (displayed by leaves) that can be used to upgrade the abilities and skill of that plant, which increases the probability and effectiveness. Some skills and abilities can only be upgraded once the Hero Plant has reached a certain level.
