Over the years, I’ve used my share of literary characters in my own gaming sessions. Doctor Who, Doctor Doom, Darth Vader, Freddy Krueger, and the entire cast of characters from the old, Marvel Comics War of the Worlds (Martians included), have ALL made appearances in my adventures at one time or another. HOWEVER, I did so in the privacy of my own home with my select gaming group, not posted online for the entire world to see. The former is okay, posting or offering them online is NOT.
In other words, if you want to convert to use in your own game, go ahead. But don't post it.
