Cyclops

The Cyclops one of myths more famous creatures of tales of old. Usually calling the highest mountain regions and remote islands their home Cyclops are often placed by the gods to protect something of value, to guard it form the greedy an unworthy or to test great heroes for the gods amusement.
Cyclops are giant and extremely durable and strong enough to hurl great boulders at enemies they face , often using whole trees crafted into weapons to crush and smash foes to meal, although most would rather grab you and take you home as dinner such remote places have little food as and they have giant appetites, more friendly Cyclops are lonely and would rather cage you up if it means they have company.

Note: like all Giants Cyclops are resistant to magic and their skin is so thick its like armour against arrows, but a Ballista (Bolt thrower) would work if fired repeatedly.
