Don't know how many even know Dark Souls, but...a Smoug-inspired Sion skin would be cool

He'd have lightning particles for his E and W. His proportions are altered to make him more pear shaped. And his axe will be changed into a big ass golden hammer covered in blood.

Oh, and his R will have him doing Smough's hammer-charge attack with him ending it in an upswing just like Smough does.

Hell, he can even be complimented by another champion with an Ornstein-inspired skin! Unfortunately there aren't any spear-using champions weak and useless enough to qualify being an Ornstein. And yes, Ornstein weak and useless despite how cool he is, easier to dodge, easier to kill.
