Doctors Without Borders is an international, independent medical humanitarian organisation that provides emergency medical care to people affected by armed conflict, epidemics, natural disasters, and exclusion from healthcare. Operating in more than 70 countries, Doctors Without Borders delivers lifesaving assistance to people in crisis regardless of ethnicity, religion, nationality, or political affiliation. Doctors Without Borders' actions are guided by medical ethics and the principles of independence, neutrality, and impartiality.
Chopper seems to embody the principles and values of Doctors Without Borders. This shared stance and philosophy led to this collaboration. This initiative aims to broaden understanding and interest in Doctors Without Borders' humanitarian medical activities.
"I am truly delighted that Chopper, the doctor of the Straw Hats, has been given the opportunity to play an active role on the global stage,” says Hiroyuki Nakano, ONE PIECE Media Editor-in-Chief. “He is originally a reindeer who became a ‘Human-Reindeer’ after eating the ‘Human-Human Fruit’. Yet he dedicates himself to treating anyone who is injured or ill—whether human or animal, friend or foe.”
“Because of this compassion and determination, I believe he is a perfect fit to serve as a supporter of Médecins Sans Frontières, an organisation that provides medical care on the front lines around the world, transcending borders, race, and religion,” continues Nakano. “We hope you will support his activities. Congratulations on your appointment, Chopper!”
I am delighted that MSF has gained such a wonderful ally. I have been covering the organisation’s activities since 2016, visiting eight countries or regions to date, and compiling my experiences into books. In this increasingly chaotic world, I intend to continue observing the work of those who come together around the core values of medical care and humanitarianism—both myself and Chopper.Seiko Ito, Japanese author and creator
Meet Tony Tony Chopper
The doctor of the Straw Hats from ONE PIECE, the manga created by Eiichiro Oda. Originally a blue-nosed reindeer, he became a ‘Human-Reindeer’ after eating the ‘Human-Human Fruit’ (Hito Hito no Mi). He carries the will of his mentor, Dr Hiriluk, and aims to become a ‘Panacea’ – a doctor who can cure any disease in the world.

Chopper runs wearing a Doctors Without Borders logo T-shirt, a stethoscope around his neck, and a Doctors Without Borders flag raised high. His bulging emergency medical backpack is modelled after one actually used by Doctors Without Borders staff. Chopper’s running form evokes a sense of kinship with Doctors Without Borders' ‘Running Person’ logo, which embodies the spirit of Doctors Without Borders.

Congratulations, Chopper, on becoming an official supporter of Médecins Sans Frontières (MSF)! I’m thrilled that Chopper, the ship’s doctor of the Straw Hats, will be supporting the activities of MSF.

Collaboration website, booklet, content
Several activities are planned for Chopper to carry out in support of Doctors Without Borders. A special MSF × Chopper collaboration website is one of them, and is now online. Visit: https://www.msf.org/chopper.
A Doctors Without Borders official introduction booklet, What is Médecins Sans Frontières?, featuring Chopper as the navigator, is currently in production. It will allow readers to learn about Doctors Without Borders' activities together with Chopper, and is scheduled to be published on the special collaboration website.
In “CHOPPER’s,” which depicts Chopper living in the modern world we inhabit today, we introduce the work of Doctors Without Borders as a ‘journey of discovery’. Explore the work of Doctors Without Borders together with Chopper as he visits sites across the world. The contents can be viewed on the official CHOPPER’s website, Instagram, X account, or the special collaboration website.
Production of original goods to support Doctors Without Borders' humanitarian activities is also planned. Details will be announced later on the special collaboration website and on CHOPPER’s social media channels.
