synopsis
The Brain is back, and if anything he's nastier than ever. This time out, the Brain has teamed up with Reflecto from the planet Imago for the purpose of creating an Aquaman clone. Their master plan is to replace the orginal with the duplicate, then conquer Atalantis. At first, the ever-trusting Aqualad doesn't realize that the Aquaman lookalike is a phony, but the evil doppelganger soon reveals his true nature--just in time to be vanquished by the genuine "Sea King."
