Ban Hammer was unnaturally spawned at The Heights by Windforce, one of the seven deities of the Inpherno. Ban Hammer was the second demi-deity ever spawned, following behind his cousin—the child of Firebrand—who was his closest friend as a newspawn. Windforce raised Ban Hammer in her image, and the two share an extremely close bond, with Windforce being very proud of her child and his accomplishments.

Six years prior to the events of PHIGHTING!, Ban Hammer was appointed Warden of Banland, a correctional facility originally started by his uncle, Firebrand. Windforce first took the reins following Firebrand's disappearance, but passed it down to Ban Hammer, who took the job in stride. He oversees the main island of Banland, as well as smaller police forces stationed around Crossroads. He is hated by the general populace due to his tyrannical role as Warden and for being related to the Swords; despite this, he ultimately strives to make Crossroads a safer place for everyone, even if his methods may sometimes fall short.

Ban Hammer is incredibly strong in comparison to normal inphernals, possessing an indefinite lifespan, much like the deities before him, and he willingly blindfolds himself as a personal "challenge" to his strength. He has a set of wings similar to his caretaker, which he is able to summon and de-summon at will, as well as four eyes under his blindfold, with two on each side.

Ban Hammer does not align himself with any faction in the Inpherno, and prefers to keep to his own, leaving him with a distinct lack of other inphernals in his circle. Despite this, he has a strong one-sided rivalry with Scythe, a notorious and formidable criminal who has continued to evade his grasp.[4
