Bastian

The Three-Headed Hellhound Bastian, also known as Ah Bas, is also Wrath of the Seven Deadly Sins. He is Roland's loyal dog and one of his strongest fighters. He is the leader of the Red Hunting Hounds.

History
Bastian was originally Roland's dog. After becoming an undead, Roland used him to create Wrath. Bastian became Roland's general and lead the Red Hunting Hounds to many victories during the Yongye Calamity. After Yongye's defeat, Bastian followed Roland back to Sulfur Mountain City where he lived in peace, worked in the undead amusement park, and later fought in the battle against the Demon Count attacking Sulfur Mountain City.

Abilities
Wrath is typically separated out into two dogs, Ah Bas and Ah Bao. When the two are combined, they change back into their original form. The left head is Ah Bao, the right head is Ah Bas, and the center head is the incarnation of Wrath. The right head is in overall command of the body.

As the incarnation of Wrath, Bastian gets more powerful the more angry he is. Over the course of a battle, he will continue to get stronger and larger.

Bastian has an ability called the Soul World Gates of Hell. When it is used, Ah Bao opens the left door while Ah Bas opens the right door. The right door unleashes the air of death which kills those exposed to it. For every 10 killed by the right door, the left door is able to resurrect an allied undead who still has his soul intact.
