Nezha protecting the map of Samadhi

Nezha is a heavenly deity from the Celestial Realm, serving as both a member of the Celestial Court and a guardian. Nezha is a stern and responsible celestial. He is occasionally short-tempered, mostly in regards to the Monkey King, though he is shown to be understanding and kind. He is often seen being understandably exasperated and annoyed.

Nezha is an adult, with shoulder-length black hair that fluffs out towards the bottom, the top half of it is in twin buns that are tied with red ribbons. The way his hair is curved around his head implies he has pointed ears. He has red circular makeup above his eyebrows. Nezha's boots are equipped with Fire Wheels, a pair of blazing wheels that grant him incredible speed and the ability to soar through the air. When Nezha is stationary, the wheels enable him to effortlessly hover above the ground.

Nezha can summon his spear from far and long distance. Nezha is among the fastest among the Celestial Court, with Sun Wukong even claiming Nezha has always been faster than he is albeit inferior in physical power. Nezha can conjure a protective magic barrier, which serves as a defense against incoming attacks for both himself and others. Nezha can generate lotus petals that can sharpen to pierce through objects and explode. He can also turn his spear into petals. When he is hit with great force petals may also generate. Nezha possesses the ability to generate energy seals that have the power to seal objects. For instance, he used a seal to safeguard the Map to the Rings of Samadhi. Most seals have the ability to counter anyone, but destroying a seal could have fatal consequences. Nezha can create pink fire, usually using the Fire Wheels.
