This is for the blizzard student art contest which sounds really fun.
I'm not eligible to enter but whatever :p. My concept is a rat catcher.
Still fiddling with his story.
I dunno if he should be a rat who is bent on revenge against humanity, funding his plans by catching rats.
He doesn't kill the rats but trains them? live cage of rats? or maybe rats hidden in his sleeves or clothes?
He was experimented on? give him a mutated human ear?
Or maybe he doesn't care for his brethren?
Should he have a crossbow? but that's like twitch from Lol.
So maybe a flute like the pied piper?
