User blog comment:Nobody700/What DC character do you want to join?/@comment-24476516-20160924195653

For Arrow, I say Onyx. Was a Star City vigilante in the comics, former League of Assassins member, and with all the season 5 vigilante influx in Star City, still no sign of Onyx on the show? She's perfect!

For Flash, Elongated Man. He got mentioned by Wells in S1, is a classic Flash character in the comics, and, best of all, this could lead to an Arrowverse adaptation of Identity Crisis!!!

For Legends, Spectre. We met Jim Corrigan on Constantine! C'mon, DC, you're doing JSA, bring in the Spectre! Make it happen! Since he's sent by God it could make Rip Hunter all happy and "man, there IS a heaven my family could be in!" or something, eh?

For Supergirl, the Anton Schott Dollmaker. Somehow. Winn turned evil? Evil Winn counterpart? Long lost evil Winn brother? Some Schott that got influenced by the Barton Mathis Dollmaker from Arrow, should the shows' Earths combine? I'm in for any of them!
