Freed Sellzen

Freed Sellzen was a recurring antagonist in High School DxD. He was a stray exorcist who first allied with the Fallen Angels in Raynare's plot to steal Asia's Sacred Gear.

Appearance
A young man with short white hair and red eyes.

As a priest, he was dressed in clerical clothing and often had a disturbing smile on his face.

As a Chimera, he had a massive body, thick arms and legs, and sharp fangs coming out of his mouth. He also had a single bat wing and an extra arm coming out of his back.

Personality
Freed was a psychopath and a battle maniac, he preferred violence over logic, spoke in a vulgar manner, and was somewhat insane. He killed monsters and Devils for the sake of his own pleasure. He also had no qualms about killing humans. Freed was also shown to be a pervert, as he once threatened to rape Asia for disobeying him and even asked Raynare to have sex with him in exchange for saving her from Rias.

History
Freed previously trained at the same institution as Siegfried, and was considered to be a genius exorcist at the age of 13. Freed, however, did not believe in God from the start, as he only wanted to kill monsters. Eventually, he became a wanted criminal at the Vatican and was forced to run away, joining the Fallen Angels in the process.

The Red Dragon Emperor's Awakening
He first appeared in the first light novel after killing Issei's client before attacking Issei who (at the time) was lacking any battle experience, and nearly killed the latter if not for the timely arrival of the Gremory Team. When Issei, Yuuto and Koneko went to the abandoned Church to rescue Asia Argento, Freed reappeared in front of them, revealing that he was working under Raynare and battled the three of them before retreating after being at a disadvantage. After Raynare was defeated by Issei, Freed showed himself again with Raynare ordering him to save her but was rejected by Freed who then abandoned her and retreated after proclaiming that he would be the one to kill Issei.

Birth of the Breast Dragon Emperor
Freed reappeared in Volume 3, this time as Kokabiel's underling after they stole three of the Excaliburs. When Issei, Koneko, Yuuto and Saji formed a temporary alliance with Xenovia and Irina Shidou to destroy the Excaliburs, Freed showed himself to them, wanting to test the power of Excalibur Rapidly before retreating with Valper Galilei as Irina, Xenovia, and Yuuto chased them. After Kokabiel fended off Irina, gravely injuring the girl, Freed was handed the four Excaliburs: Rapidly, Transparent, Nightmare, and Mimic by Kokabiel, prior to them being fused together. Freed then used the Fused Excalibur to battle Yuuto and Xenovia but ultimately lost after the revelation of Durandal and was cut down. His body was retrieved by Vali Lucifer along with Kokabiel and was kicked out by Azazel before he joined the Khaos Brigade.

During his time in the Khaos Brigade, Freed's body was modified into a Chimera and appeared in Volume 6 during Rias and Diodora's supposed Rating Game, devouring Diodora's two Knights and further reveals Diodora's past act on Asia, angering Issei and Yuuto before being cut down by Yuuto in a flash.
