is a fictional character in the Soul series of video games. Created by Namco's Project Soul division, he first appeared in the original Soulcalibur and its subsequent sequels, later appearing in various merchandise related to the series. He is voiced in Japanese by Banjō Ginga for Soulcalibur and Ryūzaburō Ōtomo in later titles; in all English-language versions of Soulcalibur II, Astaroth was voiced by Jay S. Gilbert.
Introduced in Soulcalibur, Astaroth is a golem created by a cult worshiping the Greek god of war Ares to locate a cursed sword named "Soul Edge". Though Astaroth has consistently pursued the sword, his character has changed as the series progresses, eventually transforming into a power hungering creature desiring to consume the sword. Regarded as an iconic character of the series, Astaroth has been noted as fitting a large character stereotype seen in fighting games, featuring strong attacks but slow speed. Astaroth has been described as having easy-to-master gameplay and being popular with fans of strong, hard-hitting characters in fighting games.
