Final answer:
In the Epic of Gilgamesh, the supernatural character who intervenes is Lord Shamash, the sun god, particularly demonstrated by his assistance in the battle against Humbaba.
Step-by-step explanation:
The character from Gilgamesh: A New English Version that is an example of a supernatural force who intervenes is Lord Shamash. Lord Shamash is the sun god and plays a significant role in supporting and guiding Gilgamesh. While other characters such as Gilgamesh, Enkidu, and Humbaba are important in the epic, Lord Shamash's divine interventions clearly mark him as a being of supernatural power that intervenes in human affairs. For example, Shamash aids Gilgamesh and Enkidu by sending the winds to assist in their battle against the fearsome Humbaba. This intervention showcases the theme common in Mesopotamian literature, where anthropomorphic deities engage with mortals, affecting their lives and the course of events.
