Over the past two seasons, Arrow has slowly been building up a pantheon of TV versions of some of DC’s most famous comic book heroes and villains*. And in the rest of the second season, it looks from this trailer like they’re all coming back. I spotted Green Arrow (obviously), Black Canary, Huntress, Amanda Waller and her Suicide Squad (including Deadshot and Bronze Tiger), Deathstroke, Sebastian Blood and Speedy. No sign of Malcolm Merlyn (aka the Dark Archer), who’s already reappeared this season, or China White, though.
* Admittedly, none of the ‘biggies’, such as Batman, Superman, Wonder Woman, the Joker et al
