Willie had weak flight powers until the teasing of the other children got too much for him. One day he just flew straight up into the sky and disappeared. He grew up as a normal using the name William Corealis. He was living in Chicago when Critical Maas invaded, and stayed to help the normals. When Poet, the only Special who had ever been friendly to him, was killed in the infiltration attempt, William took his body to Cathy Jean so she could bring him back to life. His debt to him repaid, William felt no obligation to assist in fighting Critical Maas and took off into the sky.
