A casting call for The CW's forthcoming Arrow/The Flash spinoff series has emerged, and TVLine shared the three "mystery" heroes previously announced as part of the project.

Well, mostly. They've got the casting calls, which of course in a project this sensitive don't actually name the characters, per se.

Here's who we have, and below that we'll share some speculation (both ours and TVLine's):

“THE TRAVELER” | A Han Solo-esque rogue who gets by with his charm, this hero hails from the future, and has journeyed back in time on a secret mission. His razor-sharp wit hides the pain of a man who has lived through serious conflict. He also harbors many secrets, always leaving both his teammates and the audience unsure of his true allegiances.

“FEMALE WARRIOR” | This twentysomething Latina is pretty but unassuming, book smart and socially awkward by day. But by night, when she hears the cry of battle, her fury is ignited and she becomes a fierce warrior — so much so, that sometimes she can become a threat to others.

“MYSTERY HERO” | An African-American male in his twenties will fill the role of a regular, street smart guy who unexpectedly gains powers, and then, as part of the team, regularly quips about the insanity of the situations.

Okay, so there's a lot to digest in there.

The Traveler is where we're in 100% agreement with TVLine; they assume that the character will be either Booster Gold or Rip Hunter, and it makes sense; not only does The Flash executive producer and DC Entertainment Chief Creative Officer Geoff Johns love both of those characters, but the description given to the character reads like a hybrid of the two.

The "Han Solo-esque rogue who gets by with his charm" is all Booster, while Rip Hunter pretty much has a trademark on "His razor-sharp wit hides the pain of a man who has lived through serious conflict. He also harbors many secrets, always leaving both his teammates and the audience unsure of his true allegiances." Where the two can't be determined is the secret mission from the future thing, which is true of both of them...although Booster is more truly from the future than Rip, who may be Booster's son but as far as anyone knows was likely conceived in this era.

The other pair -- whom TVL identifies as likely Fury or Wildcat II and Static or Black Lightning -- read slightly less obvious and really could be any number of characters, although there's certainly little wrong with the TVL guesses, provided that Static isn't tied up, either with the Static Shock webseries or in the rebooted Milestone Media.

Fury certainly seems like a solid choice for the female warrior, but any character with deep connections to the Wonder Woman mythology might be hard to get by DC Entertainment and Warner Bros. while the Wonder Woman and Justice League movies are still a going concern. There's also the fact that the current-canon version of Fury is an alternate-earth character...which would seem prohibitive, except that it would certainly allow for the return of Caity Lotz, who is reportedly signed on even though her character on Arrow was murdered.

Probably the most puzzling part of the whole thing is the Mystery Hero, who TVLine seems pretty locked in as having electrical powers but who, frankly, could have just about anything and it would be believable from that casting call. That two of DC's most marketable black characters have electrical powers and the personality sounds a bit like Static's certainly makes their argument compelling, but then, they could also racebend just about anybody, or even slightly modify some things about another black hero.

All of that said, while speculation is fun, it's always hard to know how much was handed to people off the record and whether TVLine is fixated on the electrical characters because they have good reason to believe that's who's coming.

The still-untitled project is in development and will reportedly be along at midseason next year, ordered straight to series. Also appearing will be Firestorm, The Atom and Canary, played by Victor Garber, Brandon Routh and Caity Lotz.
