Anyone fancy guessing which other heroes will appear alongside Mr X in Retro Active? They could be from ANY DCT comic.

The catlike agility sounds like Billy the Cat and Katie from the Beano, although other solo heroes do fit the same description.Throughout the 1970s and ‘80s, there were stories of teenage heroes with catlike agility, who teamed up to solve crimes, of a hooded avenger who was the scourge of the underworld, of a scientific genius in a remarkable aircraft who fought master criminals. And, from legends came tales of a mysterious girl with otherworldly powers who appeared whenever danger struck.
