Heathcliff (Hangul: 히스클리프, hi-seu-keul-li-peu) is designated Sinner #7 of Limbus Company's LCB department. Heathcliff is a brash and action-oriented man with a strong, dedicated spirit. He was previously affiliated with Wuthering Heights, having grown up alongside the Earnshaws and later working for the Dead Rabbits Syndicate prior to joining Limbus Company. He is the focus character of Canto VI: The Heartbreaking.
Heathcliff is a tall and well-built man with messy dark brown hair parted on the right side of his head. He possesses sharp, glaring eyes that are a dark shade of purple, and slit pupils. His eyebrows are the same shade as his hair and are both slit, his right eyebrow having two slits and his left just one. He has a dark complexion with a number of scars littering his arms and going all the way up to his cheeks. His work uniform lacks the typical long black leather jacket, instead including a holster which is strapped around his chest and shoulders, with his employee card hanging below his right breast. The sleeves of his Limbus Company white shirt are rolled up to his elbows. He wears a red tie, black suit pants with a black waist belt and dark gray shoes. His weapon of choice is a long metal bat with bandages wrapped around the handle and the word "REVENGE" written in sharp letters on the barrel, which Heathcliff holds in his right hand and rests over his shoulder. After the events of Canto VI, he refashioned the bat to spell out "REmember". This is also reflected on his LCB Sinner battle sprites. During his makeover in Canto VI, Heathcliff wears a formal suit in the style of T Corp., composed of a white shirt underneath a red vest and a blue overcoat with red lapels, both decorated with golden trimmings, a white cravat and dark suit pants and boots. His hair has been combed back and tied into a low ponytail.
Heathcliff is an exceptionally short-tempered and abrasive individual, electing violence as a first resort, and aggression as a way of life. He is overly impulsive and quick to anger, with consequences for those involved. However, over the course of several Cantos, a considerably calmer, more considerate, and selfless side of his personality would come to light. Though, after his canto, Heathcliff has become more willing to talk things out and have a full conversation without bursting in violence.
