Supergirl continues next Monday with ‘The Last Children of Krypton’ @8pm on The CW.
In 2005, writer Grant Morrison debuted a new version of the character based in New York City and known as The Manhattan Guardian as part of his Seven Soldiers miniseries.
In later DC continuity, he was established to be the great-uncle of Green Arrow sidekick/inheritor Roy Harper.
This version, real name Jake Jordan, is arguably the most visible recent incarnation owing to a featured role on the cult-hit animated series Young Justice.
