Comic book characters were brought to life in Cambridge on Saturday.

Dozens dressed up as their favourite superheroes and villains for Comic-Con at the Idea Exchange.

Dianne DaRosa came as a "medieval princess” Ironman.

“You can shed your regular work skin or your typical day-to-day persona," she says. "You can be Ironman or you can be the Little Mermaid or whatever person you want to be for the day.”

Organizer Alfonso Espinos says Comic-Con gives grown-ups permission to play dress up, while reliving their past.

“All the kids that used to read comic ten years ago, now they’re adults. And they’re enjoying… books, movies, films and everything that relates to their childhood.”

But it’s not just about checking out the cosplayers.

Comic book artists also get to show off their work.

“It’s an opportunity for us to showcase the talents of comic book artists in our region,” says organizer Sandra Sydor.

The first Cambridge Comic-Con was held in 2013. Since then, the event has expanded from fifteen displays to forty.

Close to one thousand people attended the day-long event.
