In the previous episode, Aquaman and Aqualad did battle against the "Terrible Trio" The Brain, Black Manta and Queen Vassa. This time out, the Aqua-Duo is up against the "Awesome Threesome"--namely those mechanical monstrosities Torpedo Man, the Magneto and the Claw. Uncovering a plot to ambush Aquaman in an underwater junkyard, Aqualad and Mera swim off to warn Aquaman--but the villains may be too fast and too strong for the heroes on this occasion! ~ Hal Erickson, Rovi
