Accelerator from A Certain Scientific Railgun HD Wallpaper

Three depictions of Accelerator, a young man with white hair, are shown against a plain gray background. The leftmost and center figures are taller and appear to be adult versions, while the rightmost figure is shorter and appears to be a younger version. All three wear a gray and white striped long-sleeved shirt and dark pants. The adult figures have a male symbol on their shirts, while the younger figure has a female symbol.
