The most vicious and trecherous of the Three Legendary Ninja's summoning creatures, Manda's 'master' is Orochimaru, though he is not very loyal, and even threatens to eat him. Even when baited with the appearence of his enemy GamaBunta, Manda still demands over one hundred sacrifices to be made after the battle. This giant snake uses several powerful means of killing his enemies: if his huge weight does not overwhelm the enemy, he can wrap his scaly body around them and constrict them or bite their head off with its deadly fangs. After battling with Jiraiya's GamaBunta and Tsunade's Katsuyu, he is pinned to the ground when Tsunade thrusts GamaBunta's sword straight through his head. After this, he threatens to kill Orochimaru if they ever meet again and disappears.

He is also known as 'Devil of the Hidden Mist' since in the Hidden Mist Village, there used to be a final Genin graduation exam - a one-on-one fight to the death. However, one day, without pause or hesitation, a young man who was not even a ninja killed over a hundred of the students. That young man was Zabuza. The one-on-one system where best friends are forced to kill each other was abolished after this incident. Zabuza is a very powerful Jounin, as we see in the fights between him and Kakashi.
