Here the red dragon called Drogon. And Rhaegal was one of the three dragons born in the wastelands beyond Lhazar, along with Drogon and Viserion. He was named after Daenerys Targaryen’s eldest brother, Rhaegar. He could be distinguished by his green and bronze colored scales, and his yellow-orange colored wings. Daenerys allowed Jon Snow to ride Rhaegal before and during the Battle of Winterfell.
