Spiderman, Batman, Iron Man and Poison Ivy will all be at Eureka! children’s museum on September 21 and 22 to challenge visitors and find out just how super they are.
Children will be able to join forces with Batman and Spiderman and battle the insidious Poison Ivy who will be brainwashing visitors with her toxins.
Iron Man will be meeting children and posing for photos throughout both days.
Visitors will also get the chance to meet real life crime-fighting heroes from the West Yorkshire Police Force.
Superhero activities are free with standard admission or with a Eureka! annual pass.
