A star body reflective of the cosmic sky, Changkyun's gift is a channel of the power of the stars. When there are none, such as in another world, his power reverts into something made of black matter with control over matter equal to that of a full black hole. By manipulating the power of the universe and the space between, Changkyun can manage to channel and manifest various gifts of the universe: from body draws to the representations of the constellations. The most frequently used channel of the stars, Changkyun understand, control and create vehicles on a whim. The smaller the vehicle, the easier to make; larger vehicles might malfunction.

The nature of Changkyun's body is the ability to burn away his flesh to reveal the cosmic changing sky underneath. His skin flakes in cindered ash when he uses his abilities too often and, in the moments of absolute control and finesse, his skin would all burn away to reveal his true form underneath: an entity of fundemental energy, dark in hue and blessed by the signatures of the universe around him scattering through as light and orbs of energy. In this form only can Changkyun control the force of the universe without thoughtful understanding: he could make a planet, break one apart, swallow a universe whole. When still flesh and bone he needs to actively think about what a star is supposed to be, what a constellation or planet exists as in thought, to use his power to generate those effects. Like the chariot, Changkyun channels the bow and arrow with ease. Naturally apt with them his ability to hit a target is abnormally accurate allowing Changkyun to land shots on moving targets at the max range of his line of vision.
