The Mutant Zombie (MCPE) is a mob that can only obtained through mods. It does not look exactly like the normal Mutant Zombie, as it has a more muscular body. It also has different attacks.
Mutant Zombies attack the player by moving their hands. They walk slowly so they are more easy to escape from them.
A diamond sword and armor are recommended for this battle. A bow can also work, while potions of harming can be useful too.
When the player kills the mutant zombie, unlike PC mutant zombies, 3 normal Zombies will spawn and attack the player.
