When the job's too big for Ant-Man to handle, it's time for Hank Pym to become...Giant-Man! But being a larger-than-life-size super hero comes with equally large problems - like when Hank rejoins the Avengers to free the Wasp from the Collector's clutches, but gets stuck as a 10-foot-tall Goliath! Or when his latest alter ego, Yellowjacket, must go large to stop archfoe the Whirlwind! Then, Hank and his fellow Goliath, the size-changing Bill Foster, have big plans - that's Project B.I.G. plans - to solve world hunger using Pym Particles! And finally, to save his Avengers Academy students from an overgrown Absorbing Man, Giant-Man must come out of super hero retirement! You'll love Hank "High-Pockets" Pym - he's a hero to look up to!
