The actor confirmed in an NBC interview that his character, the heroic Vince Faraday, will not possess any special crime-fighting abilities.
"He's just a guy," claimed Lyons. "He's been put in these extraordinary circumstances and needs to use all of his ingenuity and the help of Summer [Glau]'s character Orwell... to get back to his family."
He also dismissed the suggestion that a romance could develop between Faraday and Orwell.
"I'm a married man [in the show] and my entire journey is to get back to my family," he insisted.
Discussing his childhood, Lyons admitted that he had never dreamed of becoming a costumed hero.
"It's a bit crazy," he said. "I was the one kid who didn't want to necessarily be a superhero and I'm the one kid who got to be, so it's been a huge learning curve for me and a great experience."
The Cape will launch with a two-hour premiere on January 9. The first episode will be repeated in the show's regular timeslot at 9/8c the following Monday.
