Wall-Knight is a plant hero in Plants vs. Zombies Heroes, and the leader of the Guardian and Solar classes. Wall-Knight's signature superpower is Uncrackable, which makes him so that he can't be hurt for the turn it is played, and gives him a card.
Wall-Knight is based on the nut of a genus Juglans, commonly referred to as a walnut. He may also be based on Shining Knight (which may allude to his Solar class), a comic book superhero of the Detective Comics franchise. The way the armor of Wall-Knight puts on may be a reference to Isaac Clarke's armor from "Dead Space." His name is a portmanteau of "Wall-Nut," the plant that he is based on or "walnut" the real-life plant this plant is actually based on, and "knight," referring to the armor he has.

He's a great guy - he just sometimes has a hard time coming out of his shell.
Wall-Knight's two classes, Guardian and Solar, work very well with each other. Wall-Knight can protect his sun-producing plants like Sunflowers behind tough Team-Up plants like Wall-Nuts, allowing him to generate sun more safely. This means Wall-Knight can bring out powerful plants like Three-Headed Chomper or Soul Patch much earlier in the game, and with defensive plants guarding them, the opponent will have a hard time breaking through your setup and defending themselves at the same time. Wall-Knight can also guard aquatic lanes due to him having access to Amphibious plants, such as Water Chestnut and Guacodile.
In fact, there are some synergies only Guardian and Solar plants can use with each other. Spineapple does not only boost the typical defensive plants like Wall-Nuts, but also boosts Sunflowers and Twin Sunflowers in the process. Smackadamia can boost Mixed Nuts on top of the other nuts in the Guardian class. And finally, Poppin' Poppies and Steel Magnolia benefit Briar Rose greatly by instantly summoning more flowers or generally allowing them to take more hits, on top of being flowers themselves.
Wall-Knight can also turn into a healing wall by using Geyser and 2nd-Best Taco of All Time, as well as setting Venus Flytraps, Power Flowers, and Pepper M.D. behind his defensive wall. He can also move plants around to constantly check zombies. If things so bad, Wall-Knight can use Uncrackable as his last straw.
Wall-Knight's flaw, however, is that he has no way of boosting his plants' strength, and his superpowers don't help cover it either, as they are all defensive. This means Hearty heroes can outlast Wall-Knight while breaking through his defensive wall with Rolling Stone and Weed Spray, leaving him and his plants vulnerable to any powerful zombie that may come out sooner or later. Fortunately though, Wall-Knight has access to cards like Squash, Lawnmower, Whack-a-Zombie, and Chomper, allowing him to instantly remove any annoying zombie threat. Still, the two aforementioned tricks are huge threats to him.
When you are against Wall-Knight, be cautious of a single Sunflower or Wall-Nut he sends out, as it could allow him to easily set up and be unstoppable in the late-game. Since Wall-Knight can stall for very long, it is recommended that you finish him off as early as possible. Use sheer force, instant-kill cards, or Deadly zombies to break through his defensive wall and ruin his offensive line too.
- The player is able to unlock Wall-Knight after completing a quest as one of the player's choices. Spudow, Solar Flare, and Chompzilla are the others.
- However, Wall-Knight can only be chosen after Solar Flare has been chosen, as he will take Solar Flare's place when choosing the player's next hero.
- The rocket that appears in Wall-Knight's comic strip resembles the Rocket Science trick.
- Wall-Knight is the only male Solar hero in the game.
