I am creating an action/adventure comic strip in the vein of Indiana Jones. Currently the character’s name is Panda Jack. The strip will have a title like “Panda Jack and the… fill-in-the-blank”. I am just trying to find out how I can know if that character name is taken. If it is, does that mean I can’t have a character with the same name?
For example, I created a superhero back in 1981-1982 while in high school called Mega-Man. Never published it. He appeared in an ad in the school newspaper. I still have that character, albeit in a totally different costume from then. I don't know if I could use that name now either because of Capcom's Mega Man.
