So far, I'm strongly reminded of Jane from Doom Patrol. I wonder whether this character could develop in that direction, gaining additional personae each with their own power-set.
That would be a pretty big departure from the comics, and we only have six episodes, so I'm guessing not.
For most of his comics history, Moon Knight doesn't have much for powers - he's generally a Batman analog. He's got physical training, gadgets, and money out the wazoo (in the comics, Steven Grant is the billionaire businessman persona). He gets occasional visions from Khonshu, but those are mostly to punt him in the right general direction. He has, sometimes had a boost in strength, speed, and endurance that varied with the phase of the moon.
So, not having powers, Moon Knight gets his butt kicked sometimes. Khonshu has made a habit of resurrecting Marc.
