What Netflix animated series is based on Dota 2?

The Netflix animated series based on Dota 2 is Dota: Dragon's Blood.

The series is an adult animated fantasy adventure created by Ashley Edward Miller and produced through a collaboration involving South Korean animation studio Studio Mir and Miller’s company, Kaiju Boulevard. Netflix premiered its first batch of episodes, called Book One, on March 25, 2021.

The story follows Davion, a dragon knight who hunts dragons before becoming linked to the ancient dragon Slyrak. He travels with Mirana, the Moon Princess, while facing the demon Terrorblade and a conflict involving dragons, gods, magic, and competing cosmic forces. Several characters and concepts come from Dota 2, although the show presents them in a new serialized storyline rather than recreating ordinary matches.

Dota: Dragon's Blood ran for three books totaling 24 episodes, concluding in August 2022. It is sometimes casually called a Dota anime, but Netflix and reference sources classify it as an adult animated series. Castlevania is another Netflix game adaptation, while Arcane is based on League of Legends, not Dota 2.
