GUEST STARRING ALAN RITCHSON AS AQUAMAN!!!
A summer beach party at Crater Lake takes a dramatic turn when Lois hits her head while jumping into the lake. Before Clark can save her, a mysterious swimmer named AC comes to her rescue, out-swimming Clark and leaving him baffled. Professor Milton Fine tells Clark that Lex is behind a covert operation manufacturing weapons. AC attempts to break into the Luthorcorp Marine Center in an attempt to destroy one of Lex's torpedoes and is captured by Lex. This was a very well written episode and James Marsters did a great job playing Brainiac.
