Freed Sellzen

Freed Sellzen is a recurring antagonist in High School DxD. He is a stray (excommunicated) exorcist and a battle-crazed psychopath who sides with villains like the Fallen Angels (initially in Raynare's scheme involving Asia Argento's Sacred Gear) and later others.

He has short white hair, red eyes, and usually wears priestly/clerical clothing, often sporting a creepy, disturbing grin. Freed is a complete battle maniac who loves violence over reason, speaks crudely and vulgarly, and is openly insane/psychotic — he even admits it himself. He kills devils, monsters, and anyone in his way purely for enjoyment and shows sadistic tendencies.

He wields weapons like light swords and guns, and temporarily uses pieces of Excalibur. Ultimately, he meets his end at the hands of Yuuto Kiba (being bisected).

He's remembered as one of the series' more entertaining and over-the-top villains due to his wild personality and memorable trash-talking.
