Lightman and Velocity Vanish

Military action

When Ruby Gray was six, these two superheroes disappeared, presumed dead, at the Battle of the Sky Demon.

This incident marks a major attack by Katastrophis as well as the presumed death of two of the more prominent superheroes at the time. Perhaps the attack was a more obviously prominent event, but later details reveal that the significant point was that these two heroes were temporarily removed to the Psiaic Dimension.
