My brother is a superhero, and I could have been one too, except that I needed to go for a wee. My name is Luke Parker, I'm 11 years old and I live in a mild-mannered part of London with my mum, dad and big brother, Zack. He wasn't always a superhero, but with a name like Zack you've got to wonder if my parents had a hunch that one day he'd end up wearing a mask and cape and saving orphans from buring buildings. I mean, come on! It's what you get in a comic when a superhero punches a supervillain. Pow! Blam! Zack!
