A motley crew has assembled on the Waverider in the latest photos from "Crisis on Infinite Earths."

In a slew of photos from "Part Three," the Flash installment of the crossover, the Arrowverse's heroes assemble on the Legends' time-traveling ship. However, a few unsavory faces join them, including Lex Luthor and Pariah. Black Lightning, Ryan Choi, Kingdom Come Superman and the Flash of Earth-90 are also present. No one present looks particularly happy with their current situation, least of all Cisco, who appears to be arguing with the Monitor.
