Thunderbirds are a species of animals in Endless Utopia Online.

Biology[]

A phoenix is a large bird of prey, bigger than most birds found in Agea, with the exception of Griffons. One of their most notable characteristics is that they possess two powerful pairs of wings, and their plumage is golden, silver, yellow and white, and the feathers shimmer with cloud-like patterns. Notably, they have two long feathers in their tail that are as long as their bodies. Their claws and beak are golden, their scales cream and their eyes are vermillion red.

Being a bird, a Thunderbird is born from eggs that are roughly the same size as a handball ball. They make their nests in tall mountains or forests. When born, they are the size of a cat but can grow notably. A phoenix reaches adulthood in three to four years.

Thunderbirds are capable of using Aera, most notably in their ability to use Lightning, which appears when they fly, small jolts of lightning. Some also seem to be able to cause storms as they fly. They are also capable of using Light and Wind, and presumably also Cloud.

Despite their large size, Thunderbirds are incredibly fast. They also have enough wing strength to fly with a person on their backs backs.

They are close relatives to Phoenixes and Winter Eagles.
