Noonsa was a fishman; he had the body of a fish and the legs and arms of a human.
He was one of Zelgadiss Graywords' top four henchmen. When Lina Inverse refused to tell Zelgadiss anything about the Philosopher's Stone, Dilgear called Noonsa in and told the fishman to give Lina a kiss, an idea which horrified and disgusted Lina. Noonsa gave Lina a sucker kiss (which involved Noonsa sucking on her head inside of his mouth). Later, when Zelgadiss broke Lina out of the castle, Noonsa watched from the water and attempted a sneak attack on Lina. After a lengthly battle, Zelgadiss rescued Lina by trapping Noonsa in a bubble of air, inabling his ablility to breathe, and frying him with a Fireball. Later, some of Dilgear's followers found Noonsa's fried corpse and brought it back to Dilgear. The followers then ate Noonsa's body, which infuriated Dilgear.
