Top 10 Most Evil Demons

The Devil

The Devil is a central figure in Christian theology representing evil and opposition to God. The concept developed from earlier Jewish ideas of Satan as an adversary or accuser. In later tradition, the Devil is depicted as a fallen angel who tempts humans toward sin.

Satan is the biggest, most evil monster in all of existence and history. By the way, I heard that some people say that Leviathan is the same as Satan, but people started thinking that they were the same kinds so in reality, Leviathan is like one of Satan's top soldiers or something.
By the way, I heard that Lucifer is Satan's cousin, and Beelzebub is also related to him. They form the Triumvirate of Hell (I would suggest looking up the word).

You all knew this would be number 1. He is the absolute most evil thing in all of existence and is the ruler of Hell. He is known by many names and is recognized as an evil force in the Abrahamic religions.

Baphomet

Baphomet is a symbolic figure that became prominent in medieval accusations against the Knights Templar. Its modern image was popularized by nineteenth-century occultist Éliphas Lévi. The figure combines human and animal features and is often interpreted symbolically rather than as a literal demon.

More of a term/symbolic icon but whatever (it's also my profile pic). It originated in the 14th century as a supposed figure of worship of the Knights Templar. It is often depicted as a hermaphroditic person with wings and a goat's head.

Zozo

Zozo is a name associated with a purported demonic entity in modern paranormal folklore. It is commonly linked to alleged Ouija board experiences reported since the late twentieth century. The figure does not appear in classical demonological texts.

Zozo, the Minotaur of Hell, is a six-horned Minotaur who wears a necklace of skulls from their victims and has skeletal tattoos and markings all over their body. With a forked tongue and three tails, Zozo is the alpha bull.
This Minotaur shapeshifts into anyone and anything and serves as the gatekeeper of Hell and the Underworld.

Beelzebub

Beelzebub originated as a Philistine deity known as Baal-Zebub. In later Jewish and Christian writings, the name became associated with a high-ranking demon. It is frequently equated with Satan or portrayed as a prince of demons.

Has a devil put aside for me, for me, for me!

Beelzebub, the Glutton King, Dark Lord of the Demons of Gluttony and the Great Devourer.

One of the most popular Jewish demons, Azazel is considered a very evil spirit in Judaism and the leader of a certain class of demons that reside in the desert. In Greek mythology, Azazel is represented as the scapegoat. According to Islam, he is a fallen angel who was once one of the highest-ranked angels of Allah.

Asmodeus

Asmodeus has roots in Persian mythology as a destructive spirit. He appears in the Book of Tobit as a demon linked to lust. Later traditions depict him as a king within Hell's hierarchy.

Its real name is Valek. Someone else mentioned this, but I just want to say that his real form is that of a child, and he has a pet dragon, although I don't know the name of it. He is also third in charge of hell.

Her humanoid half has four long arms with large forearms and claw-like hands. Her body is covered in dark green scales. Her face is white with a third eye on her forehead, her eyes have a black sclera, green iris, and split pupils, fin-like ears, two horns, and razor-sharp teeth.
