Appearance:

Samael is described as an archangel, fallen angel and/or archdemon. His appearance then is typically presented as handsome and angelic, with stereotypical seraphic traits.

Purpose/Role:

An archangel, according to the Talmud, Samael is associated with Satan as an accuser, seducer and destroyer

His and Lilith's names are sometimes inscribed inside pentagrams as a couple representative of betrayal
He resembles Lucifer and is sometimes identified as a fallen angel himself

For this reason the terms archangel and archdemon are both applied to him

His behaviour varies depending on the cultural source

For example, although he encourages the sins of man, as the Destroyer, he also eliminates sinners
Christian sources refer to Samael as God's servant: an angel of death (cf. demon of fate) who is not fallen, but carries out grim duties

Historically named the guardian angel of Rome, making him a representative of Christianity (and thus, by extension, an enemy of Judaism)
Samael is the sexual partner of several demonesses, most notably among them Lilith, the first wife of Adam
