The CW has shared "a look ahead" at what's in store on "DC's Legends of Tomorrow" in its first season by debuting a new promo at WonderCon. Among the highlights in the video which is now available online is an introduction of Jonah Hex (Jonathan Schaech) and a first look at a young Talia al Ghul, Ra's al Ghul (Matt Nable) other daughter, AceShowbiz said.

Felicity (Emily Bett Rickards) of "Arrow" will apparently cross over on the spin-off, telling Ray (Brandon Routh) while still sitting in a wheelchair, "I don't think going after Vandal Savage is a vacation." Ray also sees a statue of himself, possibly in the future, in a scene that also features "Firefly" alum Jewel Staite.

In another scene, Rip Hunter (Arthur Darvill) is pointing a gun to a young boy as Martin Stein (Victor Garber) apparently opposes what he may do in order to save the world. Jay Jackson (Franz Drameh) is seen being locked up in a room and screams out Ray's name. We also see a younger Sara (Caity Lotz) before she becomes the Canary and her dad Lance (Paul Blackthorne) with hair when an assassin is sent to kill them.

Executive producer Marc Guggenheim said that Staite would play someone who has "ties to Ray." He also promised that by the end of the first season, "you'll get an answer to whether or the team succeeds in its mission to stop Vandal Savage, you'll get a resolution to the Ray-Carter-Kendra love triangle, and you'll get to know more of what the Time Masters are up to."

Teasing what to look forward to in the second season, he said that those two empty seats in the Waverider could mean new faces coming next year.
