When "DC's Legends of Tomorrow" return this fall, they won't be alone. In a handful of new photos from the Season 2 premiere, "Arrow" star Stephen Amell reprises his role as Oliver Queen -- and butts heads with a member or two of the established crew.

Amell isn't the only character crossing over into the time-traveling series. Neal McDonough's Damien Darhk also puts in a dapper appearance, while a few new faces -- including Albert Einstein's -- show up among the regular crew.

Starring Brandon Routh, Caity Lotz, Arthur Darvill and more, “Legends of Tomorrow” returns to The CW for its second season on Thursday, October 13, at 8 p.m. ET/PT.
