Viral is a member of the Human Eradication Army, who regards Kamina as a strong rival. Though being among the more humanoid of the Beastmen, his RNA contains aspects of tiger shark genetics. He pilots Enkidudu, which mainly utilizes swords and a powerful laser. He is extremely loyal to Lordgenome and the four supreme generals, and he does his best to serve them. After Kamina's death, he continues to fight Gurren-Lagann, thinking that Kamina is still alive, and he is shocked once he learns the truth. He is given the gift of immortality by Lordgenome, so that he could spread his legacy. After the fall of the empire, he resurfaces and causes an uproar with his Gunmen, calling Simon out to fight him. He is later taken into custody, and pilots Gurren during the battle against the Anti-Spirals. Viral thus becomes a 'reformed villain' of sorts. It is also shown that his deepest desire is to get married and have children, but cannot do so as Beastmen lack the spiral energy necessary for reproduction. Ultimately, he becomes the captain of the Super Galaxy Dai-Gurren and an emissary for Earth.
