Latest details for "Legends of Tomorrow" will feature Arsenal and Jonah Hex in the show, as well as the numerous deaths of Hawkman and Hawkgirl soon.

Executive Producer Phil Klemmer teased that more flashbacks from Kendra Saunders/Hawkgirl (Ciara Renee) and Carter Hall/Hawkman's (Falk Hentschel) within the show. Fans have already seen the shocking death of Hawkman at the hands of Vandal Savage (Casper Crump) during part 2 of the Pilot episode, but this does not mean it will be the end of the character itself. Klemmer told TV Guide that Hawkgirl will gradually remember all of the events in her past lives in different periods and all of that knowledge from her 208 deaths will give her the strength to defeat Savage once for all.

Both Hawkgirl and Hawkman have the ability to reincarnate to another period of existence once they have been killed. The flashbacks will give viewers an opportunity to explore the depths of Renee, Hentschel and Crump's characters within the show. This will act as some sort of "training" session Kendra in order for her to prepare when the team faces Vandal Savage again in another period of time.

Kendra's memories of her past life could have an affect on her relationship with Carter since they are originally lovers from their first life in Egypt, thus giving it a reason that they are destined for one another. On the other hand, Kendra could also have rekindled feelings with Cisco Ramon (Carlos Valdes) of "The Flash" now that Carter is out of the way for now. Valdes stated in an interview that Cisco will have a unique take in "Legends of Tomorrow" soon, Screenrant reported.

In other new, two DC characters are speculated to appear in several episodes of "Legends of Tomorrow" soon.

The showrunners confirmed that Jonah Hex will be appearing in the show portrayed by "Ray Donovan" star Johnathon Schaech, Schaech already tease fans by posting a photo of himself in costume on Instagram, although he did show the disfigured face of Jonah Hex.

Jonah Hex will be appearing in episode 11 as Rip Hunter's (Arthur Darvill) team will land in the Old Wild West and they will explore a small town called Salvation. Hex in the show is described as a "morally ambiguous gunslinger with a penchant for danger".

Aside from Jonah Hex, "Arrow" star Colton Haynes teased fans from last year's AsiaPop Comic Con that Roy Harper/Arsenal could be featured in "Legends of Tomorrow" stating that "he is one call away". Arsenal recently returned to Star City in the last episode of "Arrow" season 4.
