'Moon Knight' Explained: How Do Arthur Harrow's Powers Work?

Moon Knight landed on Disney+ on Wednesday, March 30, revealing a new roster of heroes, and villains, into the Marvel Cinematic Universe (MCU).

Alongside Oscar Isaac's dual character Steven Grant/Marc Spector, there is Ethan Hawke's Arthur Harrow, who is a man of mystery as far as the show's first episode is concerned.

Harrow is the avatar of the Egyptian god Ammit, and by being her vessel he is able to use some of her awesome power.

Here is everything you need to know about how Harrow's powers work.

How Do Arthur Harrow's Powers Work in 'Moon Knight'?

Harrow first makes an appearance at the start of Moon Knight, where he is seen breaking glass and putting the pieces in the bottom of his shoes.

While the act is not explained directly, it can be interpreted as Harrow using a form of punishment to show his piety to Ammit.

Later in the episode, Steven meets Harrow when he inexplicably travels to a small village in a European country, which is either Germany or Switzerland.

Steven comes across a huddle of people gathered around the villain, who asks for fellow believers to come to him to be judged by Ammit.

In Egyptian mythology Ammit is a deity who works alongside Osiris, the god of the underworld, and she is described as the "eater of the damned" in the funerary books of the New Kingdom in Ancient Egypt.

British archaeologist Joyce Tyldesley wrote in her book "Myths and Legends of Ancient Egypt" that Ammit devours the hearts of people who fail the test to gain admittance into the Field of Reeds.

The test sees a person's heart be weighed against a feather of truth (or Maat) and if they are virtuous the scales will see the heart be lighter, but if it weighs heavier then they will face a "horrific future of eternal chaos."

By eating a person's heart, Ammit ensures the guilty person would be "doomed to haunt the living as a malevolent, restless ghost" or be "consigned to the outer darkness beyond the created world," per Tyldesley.

This mythology is applied in Moon Knight, with Harrow taking the hands of a person and watching as the scales tattoo on his forearm deems them worthy or not, either turning green or red depending on the outcome.

Harrow's cane features two crocodile heads at the top, a reference to how Ammit is depicted with the animal's head, and Harrow balances it between his arms so it can swing side to side like a set of scales.

A person who lacks virtue, no matter if they haven't yet committed a sin, will have their spirit absorbed by the Harrow, as shown in the first episode.

It is through the cane that Harrow is able to harness some of Ammit's power, as he later tells Steven at the British Museum that she was confined by other Egyptian deities and "her own avatar" and so cannot use her power herself.

Moon Knight airs Wednesdays on Disney+.
