I'm taking Steve Rogers as a given, the first time he's in the UK long enough for them get him on the show. Probably Clint Barton, if they mention Robin Hood and give him a chance to show off his archery. And definitely NOT Natasha Romanoff, her skills set does not fit comfortably with children's TV. Not sure about Bruce Banner, but I think another no, due to shyness, though maybe Hulk would like a badge if some of the other Avengers have them.
Would any of them have badges before they became famous, e.g. as a kid Bruce visits England and happens to be involved in some activity that gets him on the show? Clint's circus days?
