Kunpaetku (クンペトクー Kunpetokuu) is the High Priest of the Fygul Cestemus sect and was the one who created Astaroth at the God of War's request. He, however, wanted Soul Edge to himself, so he could turn into a god. Unfortunately for him, Ares' agent of death, Ker, dwelled inside the monster and Kunpaetku lost control over him. Trying to use a curse to control him again, he only obtained Astaroth's rage and the destruction of his shrine, the Shrine of Kunpaetku. He survived only to find Maxi, who seemingly killed him shortly after.
In Soulcalibur V, it is revealed that Kunpaetku managed to survive his killing at Maxi's hand and fought with the other sects of Fygul Cestemus over Astaroth's heart, which was brought back by Ashlotte. He succeeded in obtaining the heart, using it to create a new Astaroth and then mass-produce them into a hoard.
They are apparently slowly getting back to their feet following their almost-extinction in the last game, restoring their old research and getting back their armies of monsters.
In Soulcalibur V, Kunpaetku's body is now half-golem. He's also renovated the arc priests in order to restore all the cult's techniques and technology lost during Astaroth's rampage.
