X: The Man with the X-Ray Eyes

Dr. Xavier develops eye drops intended to increase the range of human vision, allowing one to see beyond the visible spectrum. Believing that testing on animals and volunteers will produce uselessly subjective observations, he begins testing the drops on himself and soon discovers that he can see through people's clothing, and uses his vision to save a young girl whose medical problem was misdiagnose. Over time and with continued use of the drops, Xavier's visual capacity increases and his ability to control it decreases causing shocking changes in the doctors persona.
