Seoul ended its 2026 Han River Drone Light Show program with a Marvel-themed aerial production that placed 2,000 drones above the river for a sequence featuring Thanos, Iron Man and Doctor Doom. The performance formed part of promotional activity for Avengers: Doomsday and served as the final show in this year’s series.
A record-scale finale
According to the Seoul Metropolitan Government, the Halloween event used the largest number of aircraft in the history of the Han River series. The drones rendered recognizable characters from the Marvel Cinematic Universe, turning the waterfront into a large nighttime canvas for the film campaign.
The aerial display was paired with ground-based attractions. Visitors could enter a photo zone built around Avengers: Doomsday, including imagery based on Doctor Doom’s throne and stained-glass designs. Organizers also arranged a costume parade and event booths before the evening performance, while a social-media activity offered Marvel merchandise to the first 1,000 eligible participants.

Drone shows become a city attraction
The event was also the latest example of Seoul using coordinated drone performances as a recurring public attraction rather than as a one-off celebration. City figures cited in the report show that seven shows held through October 9 attracted approximately 197,000 visitors, averaging about 28,000 people per performance.
That attendance gives the Han River program a scale beyond the viewing area directly beneath the formations. Large public drone displays can be seen from multiple points around a waterfront, while their visual content can be designed to shift between characters, logos and narrative scenes during one performance. In Seoul, the format has been combined with seasonal events and entertainment programming to encourage visitors to remain at the venue before and after the flight.
The Marvel finale connected that city program with a major film release campaign. Rather than relying only on theater advertising, the event used the night sky itself as the presentation surface, with the drones translating familiar characters into moving light formations above one of Seoul’s most prominent public spaces.
A wider promotional event
Avengers: Doomsday is described as a major crossover production bringing characters and franchises from across Marvel’s cinematic universe together. The announced cast includes Robert Downey Jr, Chris Evans, Chris Hemsworth and Pedro Pascal, with Joe and Anthony Russo returning to direct after working on Avengers: Infinity War and Avengers: Endgame.
For aerial production teams, the Seoul performance demonstrates how drone shows are being used as branded visual events that combine large-scale choreography with on-site installations and audience programming. The Seoul Metropolitan Government’s attendance figures also place the drone display within a continuing public-events strategy, with the 2,000-aircraft finale marking the largest edition of the city’s 2026 Han River series.
