Stephen Amell will sport that iconic Green Arrow goatee, but not on "Arrow". Executive producer Marc Guggenheim has confirmed that the actor will guest star on "DC's Legends of Tomorrow" as a future Oliver Queen.

"Every once and a while, we do an episode where the 10-year-old me has to pinch himself," Guggenheim says. "We're not only introducing our version of Connor Hawke to our universe, we're going to meet the 2046 version of Oliver Queen, and Stephen Amell is going to be reprising his role from 'Arrow'."

He further teases, "As an added bonus to comic-book fans, Oliver is missing his left arm and will be sporting a goatee, in a nod to the character's appearance in the seminal 'Dark Knight Returns'. We think this episode features some of the coolest things we've ever done."

Future Oliver Queen will appear in the sixth episode of the season. Other "Arrow" characters who are set to make appearance on the new spin-off series include Damien Darhk (Neal McDonough) and Ra's al Ghul (Matthew Nable).

"Legends of Tomorrow" airs Thursdays at 8 P.M. ET on The CW. In the third episode titled "Blood Ties" that will air February 4, Rip decides to weaken Vandal Savage by going after his financial assets. Rip and Sara infiltrate Savage's bank, but are discovered by his men. Meanwhile, Snart and Rory talk Jax into taking the jump ship back to Central City so they can steal a valuable emerald. Professor Stein guides Ray on a dangerous mission.
