Comic superheroes such as Batman and Spiderman have a new rival - in the form of Britain's Prince William.

The royal romance between Prince William and Kate Middleton is being chronicled in a graphic novel due out in April, just before the couple get married.

It's called "Kate and William: A Very Public Love Story", and it tells the story of a beautiful girl who goes to university and wins the heart of a handsome prince.

The comic is a fusion of two stories, each with its own graphic style.

The first is William's life story, drawn in an artistic style that echoes the all-action comic heroes of the 1950s.

The second is told from Kate's perspective, based on romantic comics popular with British schoolgirls.

The publishers, Markosia Enterprises, released a number of comic panels ahead of publication.
