18 appearances (over 18 pages) from issue no. 1 (24/09/77) to no. 18 (21/01/78).
All were printed in black and white.

Ava is described in the title frame as "Strong as an ox - gentle as a lamb." It's also said of her there (in issue nos. 3, 6, 12 and 18) that "She wants to be a world champ" and (nos. 4 and 15) that "She's the world's strongest girl," but in neither case does this seem to tally with any of the stories in the strip.

Charlton Veston is her complete opposite - a bespectacled weakling school friend and trainer. He appears in all but two of the stories - issue nos. 4 (though he still received a co-credit in the title frame) and 10.

Their bookish school friend Emma Swot appears in issue nos. 2, 3, 4, 5, 8, 10, 11, 13, and 14. Most of the stories take place in a sports or school environment.
