Arbiter Azir. Champion Skin Idea

So Azir has golden armor on, that is more of an energy of light than a sandy-gold. His chest radiates with light energy, so you can see that he has a somewhat hollow chest full of light energy.

His soldiers are beings of light with armor kind of loosely hovering over their limbs. When they appear, there is a small orb, kind of like a golden star. The star then explodes/implodes (whatever you think would be cooler) to form his soldiers. His link between his soldiers would be a chain of light with chucks of metal rotating around it, kind of like a metal link that was fragmented with light running through the center.

When his soldiers dash, there is a flash of light in a line to their target location, and there is a bit of light that loosely circles around them. When Azir dashes to his soldier, the chains light intensity increases, and Azir levitates off the ground and his feet glow until he reaches his soldiers.

For his Ultimate, when he uses his ultimate, a golden solar flare bursts forward from his front, reaching its location, forming a spherical shape, and bursting into a line of sand soldiers holding shields.

Lastly, when an enemy runs into the shields, there is a sharp burst of solar energy and they are thrown a short distance back (however far they are bumped back originally).
