Tony Stark, Victor von Doom, T’Challa, Amadeus Cho… the greatest minds in the Marvel Universe all have one thing in common: they’re not smarter than a 4th grader!

They’ll need both to stand up to some of the worst villains the world has to offer – and maybe even one of its greatest heroes!

Then, Lunella has her biggest adventure yet – a journey to the Living Planet! But are you ready for Moon Girl to meet… Girl-Moon? And who exactly are Devil Girl and Moon Dinosaur?!
