Astaroth looks like a possessed human with the additional features of goat-like spiral horns, longer and sharper nails, canine like teeth, red eyes, a Demon tail, and a longer tongue.
In his major form, Astaroth's appearance becomes much likely a stereotypical Demon (with goat like characteristics like having rounded horns and standing on two goat-like lower limbs). He becomes bigger, his skin turns a dark red colour, possesses claws, his horns become much bigger, his eyes turn completely red, and his teeth become battered. This form only appears in the anime.
He is referred to in The Lesser Key of Solomon as a very powerful Demon. In art, in the Dictionnaire Infernal, he is a Demon of the First Hierarchy, they seduce by means of laziness, vanity, and rationalized philosophies. To others, he teaches mathematical sciences and handicrafts, can make men invisible, lead them to hidden treasures, and answers every question formulated to him. He was also said to give to mortal beings the power over serpents. Astaroth is not only a great prince of hell, but also the great prince of all earthly inquisitors and accusers. It is said that during the warm month of August Astaroth's power over man reaches it's peak and highest potency.
Beginning arcEditThe Demon makes his debut in the first events of the series, possessing the student Reiji Shiratori, whom Rin had previously gotten into a fight with. After goading Rin into another fight, his companions (who are unaware of Reiji's possession) jump and manage to suppress Rin. Despite his companions’ uneasiness, the Demon proceeds to draw a knife (a hot metal rod in the anime). Fearing for his life, Rin unconsciously lets loose his blue flames for the first time, proving to the Demon that he was the son of Satan whom he sought. However, before he is able to bring the “young lord” back to Gehenna, Father Fujimoto appears and swiftly defeats the Demon via an Aria chant.
In the anime, the Demon introduces himself as Astaroth, the King of Rot. After his quick defeat at the hands of Rin’s foster father, Astaroth manages to repossess the body of Reiji, leading to a second engagement, this time inside the church. Despite falling to the use of his "major" form, the second battle also fails to go in his favour and after the brief skirmish with the Paladin, Rin and several other Exorcist that resided in the church, the Demon who called himself Astaroth, is once again banished from Reiji Shiratori’s body
