Hmm. That's interesting. Adding the symbol is something that might make the owner less likely to complain, but it doesn't actually create a shield for liability. Generally, talking about the comic "Harlan Ellison's 7 Against Chaos" in a descriptive way would be OK with or without the ®, while creating Harlan Ellison's Wiki and adding indicia to make it seem official or endorsed would not be. There's no harm in including it though. However, a Harlan Ellison Wiki dedicated to cataloguing and commenting on his literary works would be fine, provided it doesn't create any confusion as to the source.
