Belial

Belial is a demon, one of the 72 Dukes of Hell, and Diablo's subordinate.

Physical description
Like other demons, Belial can possess the dead bodies of humans using the deceased's soul. Due to this, they can assume any human form as long as there are souls available.

In his true form, Belial can be described as a gigantic being with big horns and wings. He looks like a mixture of several weird species.

Personality and traits
Belial has a big ego thinking that he can get anything he wants due to his status as a Duke of Hell. He is extremely perverted and would lay with any being he found interesting. Some demons called him Zeus' Twin Brother because of this personality. It was common knowledge for demons about Belial's perversion, and when he conquered a 'woman', he always took pictures of this conquests and kept them in a book.

Early life
Belial is one of the 72 Dukes of Hell, belonging to the Demon King, Diablo's faction. As demons, who are regarded as the 'sin' of humanity, he considers Aphrodite to be the perfect wife for him. Since she is regarded as the oldest 'whore' in the world, he reasons only a woman of her level could be worthy of being his 'queen'.

Demonic War
Belial meets Victor when the latter came to Aphrodite's place looking for information. Belial was pestering Aphrodite to be his wife, but the goddess wouldn't even hear it. Victor introduces himself as Alucard and Belial introduces himself in kind as one of the 72 Dukes of Hell. Victor ignores him, however the Duke makes a rude comment about Scathach. Victor's already bad mood becomes worse and attacks him without warning, effectively killing the older demon. Belial tries to reconnect with his vessel on Earth, but finds out he can't since Alucard somehow destroyed the 'soul'.

After the more than one year time skip, Belial is still incessantly trying to make Victor pay for his misfortunes. It all culminates when Victor killed his son, and then sends his son's decapitated head stuffed with a magical bomb to Belial's castle to provoke a war with the demons.
