Childe is a very dangerous man, being part of the Fatui harbingers. Even if he was very dangerous, he could also be very silly. He was quite the jokester and tease, even at serious times. He was a very laid back man, carefree. But who knows what he is hiding on the inside. Childe has the capability to transform into something called ‘Foul Legacy’—this is an ability that expands his power with an element called ‘delusion’. Though it takes a lot of his energy, and exhausts him to the core.
