So, figured I wanted to draw Storm King. He's a lot of fun to draw! Also, absolutely annoying towards others. I wager Cozy and Discord may at least find him fun, while the rest probably think about various exceedingly convoluted ways to end him.
Sombra is clearly not a fan.

Speaking of fans, I keep thinking of him having a bit of this… rockstar vibe to him. Definitely enough that while I was drawing this, all I could hear in my head was Scorpions' Rock you like a Hurricane. Which would, totally match his energy.

My headcanon is that he's a satyr, a creature distantly related to centaurs and gargoyles (being part-simian creatures), but that's about where the similarities end. While Centaurs and Gargoyles like Tirek and Scorpan are more of the ape-variety, Satyrs are more monkey-related. In case of Storm King, a Howler monkey and a goat.
No wonder he's so loud and boisterous, have you heard those fyays scream?

Out of all the villains (and I am not including Discord in this for now), Storm king is definitely most… fun loving. He enjoys when life's a blast, sometimes literally. But he does have the dark, and angry side. And when that comes out, you better run for the hills. In terms of physical age or biological age, I'd put him somewhere fairly old, maybe even around 60. Like a good, old-fashioned rockstar, then. A real rock-cock if you will. Still spry as all hell, and totally enjoying life conquering places. And a little crazy.

He is also very, very fluffy. Especially when excited.
