A towering humanoid entity made of shifting translucent geometry appears above a megacity skyline, its body composed of overlapping dimensional planes reflecting alternate realities — hook at second two: the entity opens both hands and a vertical dimensional tear slices through the city. Reality splits. Two versions of the city begin occupying the same space. Buildings phase through each other as competing timelines collide. The destruction is dimensional and structural: streets fold into mirrored corridors, cars fall sideways into parallel gravity planes, and skyscrapers fragment into geometric shards as their alternate versions misalign. Every movement of the entity widens the rift. Entire districts slide into adjacent dimensions. The gauntlet unfolds through a skyline progressively divided between worlds: street level where pedestrians phase between realities → mid-rise districts where buildings overlap in transparent duplicates → rooftop where entire towers rotate into perpendicular universes. Aircraft vanish into dimensional folds. Bridges twist into impossible angles. Chase-cam flying through intersecting city layers as gravity shifts between realities. Velocity ramp when the dimensional rift expands wide enough to swallow an entire city block. Cut to aerial: the megacity now exists as two overlapping worlds drifting apart. The dimensional entity stands between them. Diegetic prismatic dimensional light reflecting through fractured architecture and overlapping skylines, cinematic multiverse distortion effects, particle fragments of shattered reality, 4K.
