Green Arrows of the World vs Bow Baddies of Britain

Green Arrow was legendary enough to inspire wannabees attempting to duplicate his success. On Earth-One, the Green Arrows of the World were assembled by their namesake for their one-and-only meeting together. Among those assembled was the Bowman of Britain. However, it was really Limehouse Larkin who claimed the Bowman of Britain's identity. Seeing through the counterfeit, Green Arrow defeated his opponent and the convention resumed with all the true participants.

And lest we weep that Earth-Two's Green Arrow was unappreciated... well he wasn't, in fact he encouraged members of an archery club to audition to be his successor. Turned out he subbed for all three under the aliases of Red Arrow, White Arrow and Blue Arrow to defeat foe Bronco Bates.

Sometime thereafter, the pair invited the Bow Master of Britain, whom they invited to America to train alongside. However, as with his counterpart above, Bow Master was kidnapped and substituted by a criminal attempting to subvert Speedy and his sire. Instead, a slip of the lip regarding hummingbirds in England (which aren't native there) cause the fake to be revealed and the real Bow Master to be retrieved from his captors.

There were other members of the Green Arrows of the World and their counterparts on Earth-Two we'll next meet...
