Grass Knuckles is a plant hero in Plants vs. Zombies Heroes, and the leader of the PvZH Mega-Grow IconMega-Grow and PvZH Guardian IconGuardian classes. His signature superpower is Power Pummel, which does 2 damage on all ground lanes. If there is no zombie on a ground lane, the zombie hero takes damage there instead.

He is the hero version of Bonk Choy.


He is based on the plant from Plants vs. Zombies 2 with a similar appearance.

His name is a portmanteau of "grass," a name that refers to many species of plants in the family Poaceae, and "brass knuckles," weapons that fit around the knuckles and are used in hand-to-hand combat.


Hero description

He's the best at what he does... and what he does is punching!

Strategies strategy

Grass Knuckles starts with "Bullseye" Plants that ignore enemy Super-Blocks. Then he grows them larger with powerful Mega-Grow effects - a nasty one-two punch!


Grass Knuckles leads the Mega-Grow and Guardian classes. These two classes allow him to raise a battalion of boosted plants that are as tough as they hit hard.

Since Mega-Grow plants need time to be strong, Grass Knuckles can protect them with high-health Team-Up plants from the Guardian class such as Wall-Nuts, even when they are boosted. Likewise, he can use Mega-Grow tricks such as Fertilize to boost up what are usually defensive plants to make them able to attack the zombies, or even boost low-strength Guardian plants.

He can also protect a boosted plant with Root Wall so that it cannot take any damage for one turn. This is especially useful for Soul Patch. His signature superpower, Power Pummel, is useful for taking down weak zombies on the ground lanes or to deal up to 6 damage to the zombie hero (though in some missions, the amount of damage changes depending on how many ground lanes there are). This is also useful for protecting plants.

Another good strategy to use with Grass Knuckles is boosting plants with PvZH Truestrike IconBullseye such as Sting Bean, Cactus and Jugger-Nut, and then having them do bonus attacks by using Time to Shine or Plant Food to be able to deal large amounts of damage to the zombie hero without charging their Super-Block Meter.

Grass Knuckles' weakness, however, is that he lacks cards that can get rid of many weak zombies at once, apart from Power Pummel. More often than not, his only method of dealing with zombie heroes who use rush decks is to fight fire with fire. Additionally, he lacks easy access to damaging tricks, though he can make up for it with proper use of bonus attacks, and most importantly, Power Pummel.


Always be one step ahead of Grass Knuckles, as he is able to easily boost his plants. If he uses Power Pummel, make sure that you have a zombie in each ground lane, especially in The Foe with the Furious Fists, or your hero will take a lot of damage. If Grass Knuckles puts down plants like Black-Eyed Pea or Doubled Mint, use tricks like Locust Swarm or Super Stench in order to destroy them before they become too much of a problem.

Grass KnucklesH


  • He could be based on the concept of Grass Knuckles from Plants vs. Zombies Adventures.
  • The punching bag that appears on the comic strip after the player receives Grass Knuckles has the face of the balloon that the Balloon Zombie uses.
    • This face also appears on various objects in the game like Rolling Stone.
  • He shares his battle music with Wall-Knight.
  • In the first comic strip the player receives, it shows that a Peashooter and three other plants get turned into heroes at the same time, as one of them is Grass Knuckles.
    • However, Grass Knuckles has his own "Introducing" comic strip, in a different manner than how he was transformed.
  • Some of his idling and worrying animation is based off the drawings of it in Chinese Plants vs. Zombies Comics.
  • In the comic strip where the player receives Grass Knuckles, he is shown to be in the same Bonk Choy Boxing place in one of the extra comics.
  • His signature superpower, Power Pummel, resembles his counterpart's Plant Food animation in Plants vs. Zombies 2.
  • He is tied with Green Shadow for the most pea cards, excluding Precision Blast.
