Boreas is a minor character in the "Pastoral Symphony" segment of the 1940 film Fantasia. He also makes a cameo appearance with recycled animation from the live-action/animated film So Dear to My Heart.
Role in the film
Boreas is a two headed-cloud deity sent by Zeus. His task is to get rid of Bacchus, Jacchus, and his honorers by blowing them away. After Zeus falls asleep, he is no longer needed and therefore isn't seen for the rest of the segment.
