I wonder what the EU thought about red lightsabers before the PT? Combined with Vader’s appearance, it’s such a clear visual indicator that he is a villain. Yet, I can’t think of any Sith or Dark Jedi other than Vader that had a red saber prior to TPM.
Kharys, Flint, Brakiss, Zekk during his stint with the Shadow Academy, Sindra, the darksiders in Empire’s End, and this guy all had red lightsabers.
