Star Guardian/Dark Star Kayn
I know they already revealed the new Star Guardian skins, this idea actually just came on the spot because of it. They revealed Star Guardian Ezreal, so that means a male star Guardian isn't out of the question. In the far off future if they were to make more Star Guardian Skins... Kayn basically already fits the anime aesthetic as it is... give him a Star Guardian skin or something.
So then why did I mention Dark Star in the title? Because Kayn would present a fun opportunity to link Dark Star as an antagonists to Star Guardians. Basic Kayn can be a Star Guardian who hasn't fully accepted his destiny, or has influence from both Star Guardian and Dark Star factions. Shadow assassin can become the full fledged Guardian, but Rhaast winning can instead turn him to a Dark Star Creature.
And yes, I know making a skin like this would probably make it expensive... but that kinda is the nature of a character who has 3 different character models in game anyways, so might as well have fun with it.
