My Favorite Z-Mech on the Citadel is an achievement in Plants vs. Zombies: Garden Warfare 2. To earn it, the player must vanquish the Z7 Imp as a plant.


In the Agent Citron mission "Triangulation Station," the Z7 Imp is the boss for the mission and the player has to vanquish it to complete the mission. However, the difficult part is that it battles the player in its Z-Mech.

The player does not need to vanquish the Z7 Imp in the mentioned mission to earn the achievement. The player can also vanquish a player playing as the Z7 Imp.


  • The achievement's name is a reference to the stickerbook description for the Z7 Imp.
