Aizen had to travel across the desert with his lover as a part of the evil schemes by the Black Moon. He was severely injured by attackers and woke up only to find out that he lost his lover.

He spent day by day wandering in the desert blaming himself and plotting his revenge plan. One day, he discovered a Dragon Sanctuary and drank Dragon’s Blood, and finally turned into Talion.

Although his physical strength resembled that of human beings, he owned a super powerful gun only Talions could use. His rage and desire for retribution drove him to seek more and more power to avenge for the death of his lover.

He uses a sword to keep enemies at bay and magic guns and bombs to sentence them to death.
