He is a human teen who lives with them in the wild with his wolf pack. He was abandoned as an infant and was raised by wolves. Specifically Andrius (which is also known as the Wolf of the North or Lupus Boreas and has Cryo (ice) and Anemo (wind) powers and can speak English), who is a powerful, ancient wolf spirit who used to be a physical god, but he died during the Archon war, so his spirit (as the Wolf) protects Mondstadt. He lives with his wolf pack in Wolvendom (which is in Mondstadt), which is an area of untamed wilderness. He has long, grey, shaggy hair (that's human hair) and red eyes. He has several scars on his arms and a notable one on his left cheek. He often wears a necklace made of wolf teeth. He wears a dark, hooded coat adorned with belts over a ragged orange poncho-like shirt, paired with green camo pants and dark boots. He wears thumbless orange gloves and a single gold earring in his left ear. His Electro Vision is attached to the lower back of his coat. He has a great sense of smell. Reflecting his upbringing, he often hunches or moves with a wild, animalistic demeanor. His life revolves around his pack. He protects them above all else, seeing them as his true family. Because he was raised by wolves, he has limited social experience with humans and struggles with complex speech, preferring simple phrases. Despite his feral upbringing and intimidating appearance, he is incredibly gentle and respectful, particularly towards characters like Lisa (the librarian of the Knights of Favonius who taught him how to speak and he calls her "purple lady") and Bennett (a traveler who works at the Adventurer Guild and he calls him his "Lupical".). He treats his human friends (like Bennett) as part of his pack and is extremely protective of them. He feels most at home in the wild, enjoys hunting, and prefers eating meat over vegetables. He is often described as having "gap moe"—a gap between his scary appearance (red eyes and scars) and his genuinely sweet nature. He uses a claymore as his primary weapon. He calls his family his "Lupical", because it signifies a bond stronger than friendship—those he treasures and protects, including his wolf family (Boreas told him that).
