Double Dynamite's origins are clouded by the rumour that the first, unlettered pages of art were found in an old filing cabinet in the IPC offices, and given to Jack Adrian to add a script to. In fact, Double Dynamite was written by Scott Goodall, who had been writing for IPC sine the 1960s. The story centred around two up-and-coming boxers, Ossie Miller and Tyke Trueman, who had travelled to Manchester looking for a leg-up on the road to fame and fortune. A chance encounter with former European Light-Heavyweight Champion 'Bulldog' Brady whilst engaged in a street brawl landed the pair at Brady's Barn, the gym where Bulldog trained his fighters. Seeing potential in their untrained abilities, Brady took the pair on, hoping that with his coaching, they'd go right to the top. Along the way, the boys faced racism, corruption in the fight business and many other 'scrapes' before the crack at the big one came along.

Goodall's script is unsurprisingly traditional, laced with plenty of stereotypical northern dialogue, tha' knows, but does throw in real aspects of racism that a fighter like Ossie Miller may have experienced. The art in the early episodes was by displaced Hook Jaw scribbler Felix Carrion, who had been taken off the strip in the interim weeks. Carrion soon vacated, taking his scrappy style to the forthcoming 2000AD, joining predecessor Ramon Sola on Flesh. He was replaced by Bill Lacey, who brought a more cohesive look to the strip. He in turn, was replaced by a fill-in artist from the Rogers Agency for the final few episodes. Attempting to mimic Lacey's style, the art appears to be the work of Ron Tiner, who performed the similar task of aping Carlos Ezquerra on Major Eazy.
