OnChao is the son of Lyria and he is the only horse with wings and he brings hope.OnChao was born in the Birth Grotto with the help of two of The Element Unicorns , the Water and Wind Unicorns. At first he was shy, but opened up to Mia, who understands him and the other Unicorns. OnChao￼ helps Mia , Mo , and Yuko throughout the series. He is so far the only one who can sniff out the Trumptus pieces. OnChao is really playful, but lends a helping hoof/wing from time time. Since Gargona kidnapped his mother, Lyria , he doesn't know all of the ways of the Unicorns , but receives help from other herds throughout the series.
