Navy test pilot Mark Bartholomew asks Aquaman to help him try out the experimental vessel "Devil Fish", a combination jet and submarine. Anxious to get his hands on the invention, the Black Manta conjures up the Great Whirlpool to caputre the drylander. Leaving Aqualad behind on this occasion, Aquaman prepares to do battle against the Black Manta--but the Devil Fish proves to be a most formidable weapon when it is in the proverbial "wrong hands". Shudderin' Shad! ~ Hal Erickson, Rovi
