Tommy is based on the character of Tommy Merlyn an assassin and enemy of Arrow and an ace archer himself.
Laurel is supposed to be offspring of a cop and Black Canary, a vigilante. Her relationship with Oliver ultimately fails after many ups and downs that would make a Y&R fan dizzy.
Is supposed to be Arrow's side kick and partner but that is the nickname of Oliver's sister in the TV series.
This is supposed to be Oliver's son. His mother is unknown but discribed as a black woman. This character has not appeared in the TV series yet but perhaps that describes Diggle's SIN Carly and her son. In the comics Conner assumes the identity of the Arrow for a while.
Set to appear soon in the TV show and a vigilante. There are several characters who bear this title. But the mobster's vengeful daughter is the version the TV show is going with. In the comic her family is dead but in the TV show they are alive.
