Ned Leeds in the comics is a supporting character who has had various roles and interactions with the superhero. Sometimes he's just a regular guy caught up in Spidey's adventures, and other times he's had more significant plotlines of his own.
Some Leeds ghost stories might have originated from local folklore passed down through generations. For example, stories about haunted houses could be based on real events that got exaggerated over time.
There were stories of people getting pickpocketed at Leeds Festival. Thieves would target crowded areas near the stages when everyone was distracted by the music. Some lost their wallets with all their money, ID, and bank cards, which completely ruined their festival experience as they had to deal with cancelling cards and having no money for food or other essentials.
One well - known Leeds ghost story is about the Black Dog of Leeds. Legend has it that a large, black, spectral dog haunts certain areas. It is often seen as a sign of impending doom. Some people claim to have seen it late at night near old, derelict buildings.
In many mainstream comic universes, Ned may or may not appear. It really varies based on the storyline and the creative decisions of the writers and artists.
