Thanks to sandy4dee for the heads up.
And Awwal isn't just your average foe as he has major ties to a group of baddies DC Comics fans know very well, which also connects him to Malcolm Merlyn (John Barrowman), Oliver's (Stephen Amell) biggest adversary in season one of the CW hit series.
Negahban will first appear in episode five and is described as a formidable foe thanks to membership in one of DC Comic's most infamous group of bad guys. Meticulous, driven, and deadly, Al-Owal, whose name in Arabic means "The First," is after someone very close to Oliver. Oh, and the man knows how to handle a scimitar.
DC Comics fans will surely geek out over Al-Owal's debut episode's title: "The Demon's Head," which is the name of Ra Al Ghul, one of Batman's greatest foes (played by Liam Neeson in Batman Begins) and the head of the shadowy League of Assassins, which Al- Owal is a member of. Guess who else was a member of the League? Merlyn, who planned The Undertaking to destroy the Glades.
