Fans young and old put on their costumes and capes and made a stop at Wizard World Comic Con.
The three-day event was held at Music City Center. Big crowds enjoyed live entertainment and question and answer sessions with celebrities like Stan Lee and Val Kilmer.
They grant wishes to kids who have relapsed from cancer and young adults who have just been diagnosed with cancer.
They said the outpouring of support has been incredible.
“I can't tell you how many families have told me this is something that gave their child something to look forward to,” said Tanya Sturm, founder of Dreams and Wishes of Tennessee. “They have been through chemo and everything.”
“We love Tennessee Dreams and Wishes. It’s like Make a Wish, but all money stays local to Tennessee,” said Adam Heanen, of Tennessee Ghostbusters.
The three-day festival wrapped up Sunday afternoon.
