Mera appears in the DC Universe Online game. Prior to the launch of the game, when teasers were being released, it was established that Mera had abandoned Aquaman. During the game, however, she resurfaces apparently attacking Metropolis. It is later revealed that this was not Mera, but Circe -Wonder Woman's nemesis- in disguise. After the players are able to free Aquaman from Cercei's hold, he and Mera return to Atlantis to protect their kingdom.
