Monster

Monsters are ancient beings from the earliest Greek times that would terrorize, fight, and often kill half-bloods. Monsters are "archetypes," which means they are soulless and will just reappear in Tartarus whenever they are destroyed. This proves to be an ordeal for heroes, for after a monster is killed it can just reappear and attack again, in any time period between weeks and hundreds of years.
