John Gabrielli, also known as Gabby was a founding member of the original Newsboy Legion.
He and the rest of the newsies became the legal wards of Officer Jim Harper, the first Guardian. While they had figured out he was the Guardian shortly thereafter and often encountered him in the persona on their adventures through Metropolis Jim always refuted their allegations, thinking they'd be in more danger if they knew his identity.
As an adult Gabrielli became one of the directors of Project Cadmus and helped at least five clones--Jim Harper II, Anthony Rodriguez II, Jonathan Gabrielli II, Patrick MacGuire II, Thomas Thompkins and Walter Johnson II--obtain legal standing as US citizens. Gabrielli, along with the rest of the original newsies, was murdered by Codename: Assassin.
