On October 18, 2025, sweeping rallies labelled the “No Kings protest” rolled across the United States, with demonstrators not only voicing opposition to Donald Trump’s policies but also brandishing the distinctive black-and-white skull-and-crossbones flag from the Japanese anime series One Piece — a vivid symbol of generational dissent..
1. The “No Kings protest”: origins, scale and demand
The “No Kings protest” builds on a series of mass mobilisations aimed at challenging perceived authoritarian drift under the Trump administration. One such key wave took place on June 14, 2025, when organisers estimated more than five million participants in over 2,100 U.S. locations. Wikipedia+2Wikipedia+2
The October-18 iteration expanded this footprint: more than 2,600 rallies in all 50 states were reported. The Guardian+2Wikipedia+2

The demands spanned defending civil liberties, protecting immigrant and LGBTQ rights, safeguarding voting integrity, and curbing executive over-reach. The movement emphasised peaceful demonstration, community solidarity and reclaiming democratic norms. The Washington Post+1
2. Why the One Piece flag? A symbolic crossover
One of the standout features of the “No Kings protest” was the proliferation of the Jolly Roger (pirate flag) of the Straw Hat Pirates from One Piece. Though the link may seem unusual at first, the symbol neatly resonates with protest-culture for a younger generation.
Anime meets activism
- Analysts note that the One Piece narrative centres on a band of pirates fighting an oppressive world government — a story arc that mirrors the protest’s theme of resisting authoritarianism. Newsweek
- The flag has appeared at protest movements globally — for example, in Asia and Europe, youth activists have used it to signal resistance and unity. BOOK RIOT+1
- Within U.S. rallies, the one-piece flag functions as a visual cue: it signals a generational dimension to the mobilisation, where affinity for pop culture intersects with civic engagement.
A tool of identity and strategy
By adopting the flag, protesters achieve multiple aims:
- Identity: The icon appeals to Gen Z and younger millennials, creating a shared cultural marker.
- Visibility: The black-and-white pirate emblem stands out in crowds, media photos and social-media posts.
- Messaging: Implicitly, it declares that the movement is not simply about politics as usual — it uses unconventional symbolism to challenge traditional power structures.
- Strategy: It helps frame the movement in less conventional, more colourful terms, potentially widening engagement beyond traditional activist networks.
3. Scenes from the streets: how it played out
Across the U.S., the “No Kings protest” unfolded with both scale and local flavour. In major and minor cities alike, populations turned out in large numbers; creative expressions ranged from banners and kid-friendly art to costumed participants, some dressed as anime or pirate-characters, integrating the one-piece symbolism into local protest theatre.
Organisers emphasised planning for safety and non-violence. For example, the coalition behind the movement had trained volunteers in de-escalation and crowd coordination ahead of the day. The Washington Post
4. Why it matters: generational, symbolic, political
Generational shift
The “No Kings protest” speaks to a generational moment: many of the participants are younger, digitally engaged, culturally fluent, and using symbols (like the One Piece flag) that blend pop-culture and politics. This marks a departure from older protest templates.
Symbolic fusion
By merging a Japanese-anime symbol with a U.S. political protest, the movement underscores how globalised youth culture now intersects with domestic politics.
Political calculus
On a practical level, such protests signal to policymakers and party strategists that civic energy is alive and that younger voters are paying attention.
Long-term implications
Even if immediate policy wins are unclear, the movement helps shape future norms: for example, what large-scale civic mobilisations look like, how cultural resonance plays into activism, and how symbols matter. It also raises questions about how protest movements evolve — especially those that merge cultural icons with political messaging.
5. Challenges and open questions
- Sustainability: Will the momentum of the “No Kings protest” carry into long-term organising, or fade as media attention shifts?
- Clarity of demands: While the narrative of “no kings” is clear, translating that into concrete policy wins requires sustained structuring and follow-through.
- Broader reach: The movement has strong youth and activist presence — will it broaden to more demographics and geographies (e.g., rural America) in a meaningful way?
- Counter-narratives: With political push-back framing the protests as radical or un-patriotic, how the movement manages its messaging will matter.
6. Looking ahead
As the U.S. heads toward significant midterm elections and local races, the “No Kings protest” may influence not only rallies and marches but civic mobilisation, voting behaviour, and grassroots campaigning. .
In conclusion
The “No Kings protest” is more than another anti-government march: it is a generational moment, a cultural cross-over and a political signal. The marching crowds waving the One Piece flag are doing more than holding up signs — they’re telling a story about power, freedom and identity in modern America. How this story plays out in policy, elections and civic life may define this era’s protest-culture.
