The one everyone says his name in vain instead of god, Satan, embodiment of Wrath and King of the Wrath Ring.
I really couldn't find many, really if any, concept designs for Satan, but it's possible I was looking in the wrong places. I have seen a few theories thrown around about imps being made in Satan's image, so I went with an imp esque look without full on making him appear like an imp.
- Satan is the shortest of the sins just before Lucifer. Him being short is why he imps are so small compared to most hellborn species. It was a way to make him feel bigger since he's already about the size of your average demon.
- I feel like he likes to wear a cloak. He gives off that kind of vibe. When not wearing the cloak, he tends to wear formal clothing.
- He really gives off the "I'm just happy to be here" kind of vibe. From what little I've seen about him, anyway.
- He loves a any sport that has a lot of physical contact. Think the kind of games seen in the Harvest Moon Festival. A good brawl is a good way to spend that innate wrath.
- He likes working out. He could arguably be considered one of the physically strongest sins. He also likes yoga, but he won't tell anyone that.
- He loves imps as a species. All the shit they do, he loves it. He likes hearing about it.
- Beelzebub's dramas bore him. Majorly. He can't understand why she likes it so much.
- His favorite color is green, but despite that, he uses mostly yellow, orange, and red in his color choices.
- When he uses magic, it tends to come in the color green and typically shapes itself like circles and stars. His magic is more earth type than anything.
- Satan rarely solidly picks a side and just likes watching demons argue. He's not very good with resolutions and prefers to see things play out. He's been known to encourage arguments as well.
There's so little on Satan outside of him being the King of Wrath and mentioned mostly only in context like "Oh my Satan" or sayings akin to that, it's a little difficult to come out with solid headcanons. But, nonetheless, I tried. I wanted to deviate a bit from the typical "He loves fighting and metal music" one might often see from media's interpretations.
I'll get to Mammon one day. I feel like the design I came up for him is incredibly close to a lot of other designs already made, but it seems like most people are sticking with the same concepts.
