Wizards aid their allies with invincibility potions and give buffs such as increased firepower to Co-Star zombie hosts. Wizard Zombie is smart when it comes to magic, when it comes to asking for brainz though thats when he gets dumb. But he can use his potion elixirs to make Zombies temporarily invicible, and use his spell disaster to chase down Plants, he can also turn into  a magic ball and take a zombie to become its host and help fire at Plants. He loves brainz BUT LOVES MAGIC MORE.
