Heathcliff was a nameless Backstreets orphan adopted by Mr. Earnshaw into Wuthering Heights (T Corp). There, he formed a soul-bound bond with the daughter, Catherine, but faced vicious hatred from her brother, Hindley. After the father died, Hindley enslaved Heathcliff, subjecting him to years of brutal physical and psychological abuse. He went to pubs often and brawled. ​This trauma forged a brash, volatile, and impulsive personality. He possessed a massive inferiority complex and a deep hatred for high-class intellectualism, aggressively lashing out at anyone he thought looked down on him. Yet, beneath this brutish exterior lay a perceptive intellect and a capacity for fierce loyalty to true companions. His speech perfectly mirrored this: rough, blunt, and aggressive, packed with Backstreets slang, swearing, and biting sarcasm, completely stripped of high-class politeness. ​Physically, he was a tall, muscular young man with a dark complexion, messy dark brown hair, and sharp purple eyes with slit pupils. His eyebrows featured distinct slits, and his body was heavily scarred from Wuthering Heights and syndicate fights. He dressed in rugged Backstreets clothing and wore a sentimental ring (which is not affiliated with The Ring) on his right pointer finger. 180cm tall.
