History
The Tincture of Tininess was a magic shrinking potion given to Devil Dinosaur by Doctor Strange to ensure that the mutant Devil-Beast could more easily fit inside the Sanctum Sanctorum.
Its effects would wear off naturally in a few days or could be reversed instantly by the Gravy of Giant-Sizing; however, Moon Girl subsequently took the antidote herself in order to free Eduardo and Zoe who had been taken hostage by "Doctor Doom" and his Doombots.[1]
