Micah was played by Ryan Bollmann in Children of the Corn II.
Micah is a child from Gaitlin. He becomes the leader of the cult after Isaac's death. He becomes posessed by "The One Who Walks Behind The Rows", the demonic entity the cult worships, when John Garrett appears to investigate, what happened regarding Gaitlin.
They begin to recruit among the children in Hemingford and also begin to murder the townspeople one by one under his leadership driven by the corruption the people in Gaitlin also have. Finally they kill the rest of them and want John's son to sacrifice his girlfriend to the demonic entity. John and Frank intervene and with his son's help they stop him and the cult altogether.
