Johnny was a kid from Metropolis.
With his friends, Johnny was present at the Daily Planet's and Hubble Department Store's 87th annual Metro Merchants Parade. They stayed at the scene when a mutated General Eiling attacked, and handled crowd control at the request of Vigilante.
Johnny even went further, climbing in a tower crane to defend S.T.R.I.P.E. He hurled the wrecking ball against the mutated behemoth, allowing S.T.R.I.P.E. some time to recover. Johnny needed to be rescued himself when Eiling damaged the crane's foundations and he fell out of the cabin; luckily, Vigilante caught him. Afterwards, Johnny had a strong admiration to the hero he once considered a "stupid cowboy" before the adventure.
Johnny "Gabby" Gabrielli was a member of the Newsboy Legion, and later also of Project Cadmus.
