Ahead of next week's Legends of Tomorrow Season 4 finale, The CW has released the first set of official stills from the upcoming episode.

The photos reveal Sara Lance, Nate Heywood and Time Bureau Agent Gary Green posing as Supergirl, Green Arrow and the Flash respectively. Showing off their superhero disguises to teammates Zari and Ava Sharpe, the substitute Arrowverse trinity looks to save all of time and space from Neron in the finale, even if their costumes don't quite fit properly. The network released the plot synopsis for the season finale earlier this month.
