You guys also mentioned possibly having mythical spirit animals, so I found one for each region:
Four mythical

Asia: dragon or phoenix

Africa: DANH also DAN AYIDO HWEDO (Dahomey) Snake god. The Haitians know him as Dan Petro. The Rainbow Snake who encircles the world, Danh is often portrayed with his tail in his mouth as a symbol of unity and wholeness.
The circle was particularly important to Dahomeyan myth where the snake-god Danh circled the world like a belt, corsetting it and preventing it from flying apart in splinters.

North America: Unicorn (this is really interesting and why I chose North America for the unicorn)

South America: Quezacotl. In pre-Columbian cultures of Central America, a feathered serpent god of air and water.
