Have you ever realized that Omen and Astra are kind of similar to one another? You know, they both have their realms to where they can go to place their smokes, they both have a hood and stuff like that. But one thing I have recently started thinking about, is Astra's arm. What if Astra's arm shares the same concept as Omen's entire body.

Let me explain. In the lore, Omen has become this way he is, because he died and died because of Radiant experiments. Perhaps when Astra got her powers from the meteorite, she wanted to touch the thing and as she did, her arm got ripped apart and she got her powers. So Astra's arm is basically the same as Omen's body, just way less and in a different form. Maybe the gold that is around her arm shares the same purpose as Omen's armor: to make, that it doesn't fall apart.
