A guy from the underworld. Strugatsky A.N.

Gag, a fighting cat, a teenager, a combat unit, capable of cope with any conceivable and unthinkable surprise, and turn it to the honor and glory of his highness Duke of Alai and his house... a resident of the planet of Giganda, where for a year now there has been an unceasing war, for a year, for a year. It should have died in battle if members of the earth expedition had not arrived in time. Will they be able to teach something, to help the boy with the soul of the old man from the world of noon?
