Started on Caption This by alexgariepy. It was a series of character profiles on the major heroes and villains of Babylon 5, listing their names, AKAs, strengths, and weaknesses. A number of other Cappers (Beedo and YingYang, for example) also created a few. Later on, GlitterRock did a similiar series of "extra" profiles for background, ancilliary characters -- and even props, such as uniforms or Sheridan's beard!
When the Babylon 5 spinoff "Crusade" appeared on the Sci Fi Channel for capping, the Hero/Villain Profiles continued there as well.
