In certain comic arcs, Elektra takes on the role of the Black Sky. This identity gives her unique powers and storylines within the comic universe. However, it's not a constant or universal aspect of her character across all comic iterations.
The representation of a black sky in comics can vary. Some comics might show it realistically, while others might use it symbolically or for a particular effect. So, it's not always consistent.
It depends on the specific story arc and context. Sometimes, the Black Knight might be seen as a villain, but in other instances, he could be acting for a greater good or have redemption arcs.
