Shield Guardian Zombie (盾卫僵尸; pinyin: dùn wèi jiāngshī) is a zombie in Plants vs. Zombies Online. It carries a shield with the picture of a zombie face and a brain on it. It is quite similar to Screen Door Zombie in Plants vs. Zombies. The shield protects it from projectiles, however, unlike the Screen Door Zombie, the shield protects him from lobbed shot plants as well.
