[DISCLAIMER: I don't know much about ULTRAKILL's lore.]

Pronouns [in preferred order]: they/she/it. If you call them by she/her, they'll probably be confused, but prefer that to he/him for some reason.

Az1's backstory: They're a third machine that was secretly manufactured after V1 and V2... that's all I got.

Personality: Az1 has an interesting personality. They prefer using their fists in combat, and talk very fast. They're very intelligent, yet often act before they think.

Other: They sound like Lisa from Faith: Chapter III.

Az1 doesn't really know what to do with themselves. They mostly just screw around the different layers of hell, occasionally killing things for fuel and entertainment.

They're a lightning-fast reader. but don't read often. In fact, the only thing they recall reading is the Ferryman's diary [they found it while messing around in that area].

They're also an INCREDIBLE fiddler. Rumor has it they learned it from the "devil" himself.

It is unknown why they have a golden chain bolted to their head. Perhaps it was meant to serve as a method of identification.

They've never met Gabriel, but want to at some point, despite knowing what will happen.
