Crystal Guardian is a mechanic in Plants vs. Zombies: Garden Warfare 2. They are the plants' equivalent of the Zombot Turret. They were first seen in the IGN Commentary. Rose can build or summon them by holding and pressing the interact button (just like the Engineer) in certain predetermined spots. The Crystal Guardians can only be built in Herbal Assault to defend the portal. Its attack is named Magic Crystals, and each shot deals 5 damage.
- Unlike all other spawnable plants, Crystal Guardians do not appear to be made of any sort of biological material, or even a plant at all.
- Its body shape is similar to that of the Magnifying Grass.
- Crystal Guardian also shoots lasers, despite the attack being named "Magic Crystals," similarly to Magnifying Grass's energy bolts.
