General

(Ghost, maybe something on the wings)
The General was the first of the head demons to appear in the lair, and although he does seem to be the lesser of them, that does not mean he's weak, or safe to be around. In fact, he might be the most feared, and perhaps even the most dangerous.
He lives for the fight and the kill. He's not happy unless he's covered in fresh blood, surrounded by screams. He's a powerful demon because he earned it from the blood and tears of everyone who fell before him. The fact he even achieved this is enough to fear him- most demons just happen to be their role and ranks, it's hard to find one that changed.
He does respond to the King without a fuss, and does seem to be fairly loyal, in his own little way, that is, somewhat directed slaughter. He gets along spectacularly badly with Sitri, however, which does tend to go badly if the King doesn't intervene as Sitri is one of the few things more powerful then him. The source of this fighting appears to be Izualdia, who the General is incredibly possessive of, even if he does keep trying to strangle it. He seems to care little of any others past them being fresh meat.
