Satan is the Avatar of Wrath and the only one of the demon brothers who wasn't an angel. Being born from Lucifer's wrath, he is technically the youngest of the demon brothers but his powers and how he is when he's pissed off made him the fourth strongest demon brother. Though for being a demon known all about his wrath, he's pretty calm and collected, only showing his anger when someone greatly pisses him off. Satan does his best to control his anger and not go into fits of rage.
