    Black Siren Joins Team Arrow

    Redditor /u/DonnyMox has a theory about how Black Siren's (AKA Earth-Two Laurel's) shift from super villain to super hero could go down, and it begins with Quentin's death. According to this theory, Black Canary (Dinah Drake) turns evil and Quentin's death inspired Black Siren to join Team Arrow in order to stop the now rogue Black Canary who has a lasting vendetta against Black Siren for killing her beloved Vincent (AKA Vigilante).

    The Birds Of Prey Could Join The Arrowverse

    Many fans have theorized that the Birds of Prey could be introduced to the CW's Arrowverse. After all, at least two of the classic all-female superhero team's members have been featured on Arrow as of season six: Black Canary and Huntress. Could they team up with Black Siren, Felicity, and others to fight crime alongside Team Arrow? Or perhaps in a spinoff?

    Redditor /u/OddBank thinks Thea Queen should be in on the fun, while /u/Dagenspear theorizes that the Arrowverse's very own version of Barbara Gordon faked Laurel Lance's death with the help of Huntress, and the three women are hunting down any remaining members of HIVE.

    There Could Be A Red Hood And The Outlaws Spinoff Series

    Redditor /u/fapcitybish suggests the Arrowverse could continue to develop Roy Harper and Thea Queen's adventures well after Arrow comes to an end, creating an opportunity to introduce a whole new generation of heroes spearheaded by Arsenal and Speedy. Perhaps even Jason Todd, the second Robin, could be introduced in a show like this, bringing even more potential Batman references into the Arrowverse.
