¡Los Vengadores!

A woman with red hair and freckles looks up with a surprised expression, then her expression shifts to a more serious, focused look. The scene cuts to a black and white cat clinging to a vertical glass surface, its body stretched out horizontally as it attempts to climb, with its paws gripping the glass and its tail hanging down. The scene cuts again to a group of costumed characters standing together in a war-torn urban environment.
