Xeno is a xeno'jiiva and Kane's pet. He has blue and black skin, red eyes, and orange sensory organs on his head.
While in the Monster Hunter universe, the team comes across a fighting arena created by hunters. They infiltrate the arena by putting their own rescued beasts into the fights. They all only pretend to fight each other to give the others time to rescue the trapped beasts. Kane rescues Xeno and he's grateful.
Xeno is wise, compassionate, and was much beloved by Kane. He looked past superficial things like physical appearances and different circumstances and sees the virtues in others. He knew that Kane wasn't a hunter and let him near him without showing aggression.
He can breathe blue fire and has immense strength.
Trivia:
Xeno gets his name from him being a xeno'jiiva.
Kane states Xeno looks alien with his 6 orange sensory organs on his head, claiming his name originated from Xenomorphs.
