After selling his company for three billion dollars, Oliver Queen became a full-time vigilante, learned to master the bow, dressed himself as Robin Hood, developed an arsenal of arrows with various functions, and dubbed himself Green Arrow. Ollie was summoned to enlist in the [new] expanded Justice League. However, as he failed to reply, when he was thwarting a grocery store robbery, Queen was teleported to the Watchtower. There, he was still skeptical about joining such an organization. His main concern was helping the underprivileged in society which, according to him, tended to be forgotten by heroes whose main goal was fighting villains&monsters.
