[10] Paper rationing continuing from the Blitz is believed to have prevented an ambitious approach to the plans, but a concept design used artwork of Captain Marvel to represent a "Jack Flash" character flying amongst rockets/missiles.

The rocket lands on Earth in Colbay, Cornwall, and Flash uses his power of flight to help and bond with the villagers, usually catching petty criminals and rescuing people from danger.

An uncredited scriptwriter at DC Thomson would write each saga and an assigned artist designed artwork for a scene to fit each of the issue's eleven paragraphs.

[13] Jack Flash had six sagas featured in the magazine for nine years between issue 355 and 835, with artwork by Dudley D. Watkins, Fred Sturrock, Paddy Brennan and Andy Hutton, respectively.

[20] From issue 701 to 719, Brennan drew artwork for a story about Flash crash-landing his space ship in "Darkest" Africa, becoming marooned with schoolchildren he travelled with.

In the magazine itself, he has not returned since the 1950s, but appeared in a background cameo with Big Eggo and Jonah in a special comic strip titled Lord Snooty's Day Out in issue 3093, revealing formerly popular characters known by previous generations of readers now live in the Beano Retirement Home.
