Epic Skin Idea, Demon Hunter Darius.
(IMG IS WIP)

In this skin he would be dressed in normal leather, cloak and light plate demon hunter armor. As he progresses in stacks on enemy opponent, an appearance of possession progression would happen on his model for as long as he adds stacks. If the stacks die off he switches back to human. If he makes it back to 5 Stacks, when his passive "triggers" he'd go possessed demon form until his passive is no longer active. I am unsure what he could have as he levels up throughout the game Ideas that come to mind are,
-
as he levels his q his axe has a more advanced look to it
-
The demons i am using are like parasites and make any form they desire on the host, so each time he transforms it could be a different appearance.
-
Or you can think Immortal Zod when he transforms.
-
Unique interaction to
DemonBlade 
Demon
or any other Devil/Demon themed Champions. -

Anything I can add to this list? Your thoughts? Questions?
