Spider-Man, Marty McFly, Wonder Woman and The Joker were just some of the guests at Macarthur's first pop culture festival on Saturday.
The inaugural Nerd Con event was held in conjunction with this year's Festival of Fisher's Ghost.
Campbelltown councillor Ben Gilholme first pitched the idea for a pop culture convention earlier this year.
He said he was delighted to see the event was a resounding success.
"If I had to guess we had roughly 800 to 1000 people attend," he said.
"I think it was a great foundation for future events.
"I had people tell me they loved it, we even had people travelling from Sydney to attend."
The growing popularity of Marvel, Star Wars, DC, board games, computer games and comic books has seen multiple pop culture events pop up across the region including trivia nights, restaurant theme nights and more.
At Nerd Con, attendees were treated to range of activities, displays, stalls and cosplay competitions.
Mr Gilholme, who attended the event dressed as Gandalf the Grey from The Lord of the Rings, said it was nice to see people getting into the spirit.
"We had three categories in the cosplay competition for children, groups and individual but it was nice to see people who weren't entered in the competition dressing up as well," he said.
"It was amazing to see such a number of people dressed up."
Mr Gilholme hopes the event will become an annual convention.
"It was a great event and it would be nice to see it becoming it's own thing rather than being attached to the Fisher's Ghost," he said.
"I look forward to having further discussions about that in future.
"I would like to thank all of the Macarthur nerds for making it such a good day out."
