First Story Synopsis
Wonder Woman’s old foe Angleman is preparing to launch another attack against the might maid. He reveals his latest invention to a group of mobsters, a mechanical brain that can animate lifeless objects. When a mobster mocks this invention, Angleman shows that it works by bringing the mobsters cigar to life and using it to club the mobster into submission. When they ask Angleman how his is going to attack Wonder Woman, he shows off a newspaper clipping of a newspaper report pertaining to an expedition Wonder Woman is going on to explore an old ship graveyard.
As Wonder Woman and Steve Trevor fly to the site of the graveyard, Angleman arrives ahead of them and dumps his mechanical brain “Animox” into the water with orders to animate all the mast-heads of the ships to attack Wonder Woman. Sure enough, when Wonder Woman and Steve Trevor dive into the ocean they are accosted by an army of animated mast-heads, one of them even modelled after Wonder Woman. Although they capture Steve, Wonder Woman breaks free and spots the source animating the mast-heads. Using explosives she took from Steve, Wonder Woman plants them on Animox and detonates them, to no effect.
She then pulls the robot out of the water, and as the mastheads follow her, she reprograms Animox to order the mastheads to fly into space before tossing the mechanical brain out into space with them. On their way through the atmosphere, the objects smash Angleman’s ship sending him falling into Wonder Woman’s clutches. With the creatures also letting Steve go, she catches him as well and with Angle Man’s plot foiled Wonder Woman takes him off to custody.
