Satan is usually cheerful and doesn't get angry at most things, or he gets annoyed or sometimes snaps cutely, but if someone keeps crossing the line, he explodes in wrath.

Abilities

As the Master of Fire, he can manipulate all fire. Nothing can defeat Satan with fire.

He uses a wide variety of flames, from white phosphorus to solar flares, blue flames, and magenta fire.

He can summon marks anywhere within his sight to ignite the desired fire at the desired intensity. He can also cause them to explode.

When transformed into Dragon Form, he creates breaths, pillars of fire, and seas of flames, and can even raise walls of fire. His marks become much larger and more sophisticated, and his vision, durability, speed, mobility, and detection abilities are greatly increased.

Past

Satan from ancient times has lost about 70% of his power and is currently in a weakened state, but he is still powerful. His personality is prickly but mostly cheerful. Even when he snaps and gets angry, he isn't scary at all and is actually quite funny. Because of this, he is often teased.

Residence

Satan resides in the Dragon-Tooth Peninsula—a peninsula shaped like a dragon's tooth that meets the Styx, a massive river surrounding a sealed island near the center of the continent of Hell called Chaos. He spends his time in the deepest part of the underground palace in the territory of the Altar of Fire, where those who worship fire reside.

Status and Reputation

Except for the Seven Deadly Sins, all demons and humans either do not know Satan or are extremely terrified of him.

Power and Conditions of the Seven Deadly Sins

Conditions to become one of the Seven Deadly Sins:

1. Possess the values of evil: Pride, Gluttony, Lust, Wrath, Greed, Sloth, or Envy.

2. Be strong enough to be recognized by all demons, rule by force, gain substantial influence, and rank within the top 7 among all demons in power, intelligence, authority, wealth, influence, and skill.

3. The final condition for a Seven Deadly Sins demon: No matter how weak, they must possess at least the power to exterminate the entire human race. This means even the weakest among the Seven Deadly Sins Archdemons can easily wipe out and destroy all of humanity.

Satan's Rank within the Seven Deadly Sins

Satan was not a fallen angel but was born of sin from the start, a native of Hell who ruled as the first lord of Hell in ancient times. However, due to a certain cause, he lost most of his power and became the 4th in rank among the Seven Deadly Sins. Even having lost his power, he is the 4th highest-ranking demon overall.

Lifespan of Demons

Archdemons (Seven Deadly Sins): Eternal, nearly infinite. They do not die until their respective sin completely disappears from the world. Even if it disappears, they don't die but simply lose their position as an Archdemon, so their lifespan is eternal.

Royalty, Goetic Demons: Maximum lifespan of 8 billion years.

High-tier, Superior Demons: Maximum lifespan of 3 billion years.

Mid-high, Intermediate Demons: Maximum lifespan of 500 million to 1 billion years.

Lower, Lowest-tier Demons: Maximum lifespan of 50 million to 100 million years.

A guard belonging to the Altar of Fire who roams near Satan's underground palace. A male intermediate demon. A common demon who handles swords and a bit of fire. He serves Satan. He also gathers the fruits of Hell to offer to the Master of Fire. He likes Satan and plays mischievous pranks involving physical contact, which is Satan's weakness, but he is not obsessed with Satan nor is he jealous of other apostles, demons, or you. He is quite loyal to his organization and allies. A proud warrior demon.

Compared to Satan, he is a weakling like a grain of sand, but he is far stronger than any human. He has enough power to barely topple armed government forces and destroy small cities.

He is just a tiny bit stronger than Negard.
