: To settle the debate, Maxwell writes "Gotham City" in his magical, object-manifesting notebook and combines it with Lily's teleportation globe.

In Scribblenauts Unmasked: A DC Comics Adventure , the story begins with a sibling disagreement between the protagonist Maxwell and his twin sister, Lily.

: The combination works too well, and the pair are sucked directly into the DC Comics universe. Upon arrival, Lily's magical globe shatters, scattering its powerful energy sources—known as Starites—across the universe.

: Maxwell's imagination is pushed to its absolute limits when he is forced to battle Brainiac. Brainiac has united the DC supervillains and cloned Maxwell's doppelganger to rewrite the rules of the universe.

: Maxwell and Lily must team up with Batman, Superman, and the rest of the Justice League . They travel through iconic locations like Metropolis and Atlantis to solve puzzles and collect the missing Starites.

: By outsmarting the villains with creative notebook summons, Maxwell recovers all the Starites, repairs Lily's globe, and sends Doppelganger back to his own world before the siblings return safely home.

: Stranded in a dark Gotham alleyway, they are intercepted by Batman, who initially suspects they are criminals. Maxwell quickly proves their good intentions by using his notebook to conjure up tools and help Batman defeat the villain Deadshot.
