Status: Deceased Interferes with everyone trying to reach Mama. Merged with a Watcher and can now take the form of either a Watcher or his own appearance. After losing Third, Second lost trust in Mama and ordered Fourth to kill Sixth and Seventh herself rather than letting Mama do it; as a Watcher and as Mr. Eyeball, he tore off their arms. Eventually, Second tells him "That's enough, thank you," and the two of them enter a puddle of acid rain and die together. Because he is Fourth, when he is in Watcher form, he can even kill those who exist only as souls.
