The Legends are living a completely different life in Season 2, episode 16 of “Legends of Tomorrow.”

After obtaining the Spear of Destiny at the end of Season 2, episode 15, the Legion of Doom creates a new reality in which the Legends are no longer a threat to them. As seen in the trailer for episode 16, Sara (Caity Lotz) and Amaya (Maisie Richardson-Sellers) now work for Damien Darhk (Neal Mc Donough); Ray (Brandon Routh) is a janitor; and Stein (Victor Garber) is an employee at S.T.A.R. Labs under the supervision of a rather arrogant Jax (Franz Drameh).

Despite all these alterations, Mick (Dominic Purcell) — who betrayed his fellow Legends at the end of last episode — remains unchanged. In the promo video, Mick admits that he “made a terrible mistake” and appears to be gathering the team to go against the Legion of Doom once and for all. But the synopsis for episode 16 notes that being the hero is hard for Mick, so his mission to save the world by assembling the Legends won’t be easy.

Also in the episode, tension between members of Legion of Doom escalates, and the reason why the Spear of Destiny needs to be destroyed is revealed.

During the “Arrow,” “The Flash,” “Supergirl” and “Legends of Tomorrow” panel at PaleyFest last weekend, “Legends of Tomorrow” executive producer Marc Guggenheim revealed that there will be a huge cameo appearance in episode 16.

“I will call it a surprise crossover,” Deadline quoted Guggenheim as saying. “No one knows this because we’ve kept it under wraps, but there’s a surprise cameo, surprise crossover moment in the penultimate episode of ‘Legends.’”

In addition to the surprise cameo, the exec producer also teased an Easter egg in the episode. “I will say there is an Easter egg — it’s more than an Easter egg, it’s a little bit more obvious than that … that I think fans are really going to love,” Guggenheim said. “And not necessarily fans of comics, but let’s say fans of cartoons.”

“Legends of Tomorrow” Season 2, episode 16, titled “Doomworld,” airs on Tuesday, March 28 at 9 p.m. EST on The CW.
