Ban

Origin:
Ban is the Fox's Sin of Greed of the Seven Deadly Sins. He was formerly known as "Bandit Ban" during his earlier years and later as "Undead Ban," epithets explained by his infamy as a thief and because of his immortality. In the past he journeyed to the Fairy King's Forest to find the Fountain of Youth, encountering its guardian Elaine and falling in love with her in the process. As the Forest was being attacked by a Red Demon, Elaine forcefully gave the Fountain of Youth to Ban on her deathbed, allowing him to survive the battle. He was charged with the destruction of the Forest and murder of its guardian but couldn't be executed no matter what was tried. This led to him being conscripted into the Sins by Meliodas.

Ban used his blood to regrow the Fairy King's Forest and would later journey to Purgatory, where he lived for centuries trying to locate Meliodas' emotions. In the process he adapted to the extremely harsh environment of Purgatory.
