Milo Thatch is the protagonist of the 2001 Disney animated film Atlantis: The Lost Empire and its sequel Atlantis: Milo’s Return. He is a linguist, cartographer, and translator of the Milo Expedition to the lost city of Atlantis.


Milo Thatch was raised and educated by his grandfather Thaddeus Thatch, after his parents were killed. He took after his father, and held an interest in languages and antiquities. He was a linguist for the Smithsonian Museum in Washington D.C. until Preston B. Whitmore offered him a place in an expedition to find the lost city of Atlantis. Milo agreed, wanting to live up to his grandfather’s wishes.

When Milo reached Atlantis, he bonded with the princess Kida Nedakh. He helped her learn more about her people’s history, searching through sunken ruins to discover the truth about the Heart of Atlantis. When Commander Lyle Rourke kidnapped Kida with the power of the Heart, Milo led the resistance against them, saving Atlantis.

Milo stayed behind in Atlantis, to help them rebuild and rediscover their culture. He later married Kida, becoming king in the process.

The expedition to Atlantis is referred to as the “Milo Expedition”, named after him. In the years following the events of the film, Milo’s disappearance became a story of legend and mystery. It wasn’t until 1932 that the story went public for the first time, following an expedition by the League of Adventurers


Milo was a meet and greet character at the Disney Parks to help promote the film’s release, but was later phased out. He has made sporadic appearances in recent years thanks to the film’s cult status, mainly during special events and parties. 


  • In an unused draft for the film, Milo would have been revealed to be a descendant of Captain Edward Thatch AKA Blackbeard.
    • Blackbeard himself used to appear in the Pirates of the Caribbean.
