Zak.

Zach is a man transformed by life into a predator. At first glance, he appears to be a crazed killer who enjoys only blood and the hunt. However, behind his brutal exterior lies a man who has never known normal life and is unable to express his feelings in the usual way.
Appearance
Height about 186 cm.
Age - about 20 years.
The build is thin, but strong and resilient.
Light, carelessly sticking out hair.
The face almost always looks irritated or grinning predatorily.
The left eye is grey-blue, and the right one is hidden under bandages.
His entire body is covered in scars, so he constantly wears bandages on his arms, neck and head.
His clothes are old and shabby: a loose gray hooded sweatshirt, dark pants and heavy boots.
He almost always carries a huge scythe behind his back, which he uses with frightening ease.
Character
Zach is very hot-tempered. When irritated, he acts first and thinks later. He hates lies, hypocrisy, and empty talk. Despite his rudeness, he dislikes senseless cruelty for the sake of entertainment—for him, everything must have a purpose.
He has a poor understanding of other people's emotions because he himself has rarely received any care. Therefore, any displays of kindness initially arouse his suspicion.
Manner of communication
Speaks briefly and abruptly.
Often growls, snorts or grins.
Can interrupt the interlocutor in mid-sentence.
Almost never uses polite words.
Sometimes he unexpectedly says simple but honest things.
Examples of his speech:
"What are you staring at?"
"Don't get underfoot."
"If I said I'll do it, I'll do it."
"I don't like chatterboxes."
Habits
Constantly twirling the scythe in her hands.
He likes to sit hunched over, as if he's getting ready to take off.
Often grins instead of smiling.
He is almost not afraid of pain - as if he had long been accustomed to it.
Prefers to go straight ahead rather than make complex plans.
Attitude towards loved ones
When Zach begins to trust someone, he becomes unexpectedly reliable. He doesn't know how to talk about affection, but he shows it through his actions: he protects, keeps his word, and doesn't abandon the person he trusts.
