In "Justice League vs Teen Titans", halfway in the film the Titans have their first fight against the Trigon demons. In this scene, Kori aka Starfire, is given a cliche anime magical girl transformation scene, where her street clothes magically get shred and her normal uniform/dress appears out of no where, with a magical glow censoring everything.
Why does she get this magical girl transformation scene? This is not typical of her powers, or of DC in general.
At least Jamie has an excuse, his battle armor has always been hidden inside the blue scarab fused with his spine.
