This episode marks the first appearance of the evil Queen Vassa, who commands a huge army of predatory mermen, to say nothing of a flotilla of steel whales. In preparation for the takeover of Atlantis, Vassa kidnaps Mera to keep Aquaman from interfering (This plot twist must have resulted in a fascinating voiceover recording session, since both Vassa and Mera were played by the same actress). In order to rescue his consort and his civilization, Aquaman must punch out all of Vassa's subordinates before his final showdown with the megalomaniac queen. ~ Hal Erickson, Rovi
