Superman's Pal, Jimmy Olsen, sometimes feels like he's overshadowed by his extremely strong, flying, day-saving, super-heroic friend. Jimmy's only a kid, after all, and taking pictures and documenting the heroics of the Justice League is great, but is it really as cool as being one of the heroes?

Well, now that he's been entrusted with the incredible Supercyclopedia (it's a whole thing, you'll see it in a little bit), Jimmy hopes to be more of an action hero himself...as soon as he figures out all the cool things that he can do with its powerful alien technology. But when the villainous Toy Boy and his Mischief League of the Multiverse get their hands on knock-off versions of the device, they won't stop until they use them to devastate the fabric of space-time itself.

Can Jimmy save the day? With his buddies Rip Hunter and Linda Park by his side, he's definitely up for the challenge. They embark on a planet- and dimension-hopping adventure, encountering a who's who of the DC Universe and discovering that not all heroes wear capes. Look out, world!
