Kostas

Appears In: Young Hercules: Cheiron's Warriors

Kostas, an 'old comrade' of Cheiron's and an active soldier from Crete, is called in to be the substitute headmaster at the Academy whilst Cheiron is away at a wedding. An old-fashioned, crotchety older man, he believes in training beyond the point of exhaustion and feels that the Academy is no place for half-gods, former thieves, girls, or royalty.

When Iolaus comes up with the idea to disguise Hercules as an ogre to gain passage on a boat to Syracuse, they borrow the grouchy soldier's name.
