No, Wanda Maximoff isn't typically depicted as white in the comics. Her ethnicity and background have been established differently within the comic storylines.
In certain comic arcs, Wanda Maximoff does meet her demise. But comic storylines can be complex and sometimes she's brought back or her death is part of a larger plot twist.
Wanda Maximoff is extremely powerful. Her reality manipulation powers are nearly limitless. She can create and destroy entire worlds with her thoughts. Additionally, her magic skills make her a force to be reckoned with in the comic universe.
At first, it might be a bit rocky. Wanda is used to being on her own and having her own way of doing things. But Tony's charm and his genuine care for her would start to break down her walls. Eventually, they'd form a deep bond. Wanda would come to trust Tony completely, and Tony would see Wanda as a daughter. They'd support each other through tough times, like when the Avengers are facing a big threat.
One common theme is the exploration of Wanda's emotions. Being pregnant can bring a whole new set of feelings like fear, excitement, and protectiveness. Fanfics often delve into how she copes with these emotions while also dealing with her powers and her place in the Marvel universe.
One interesting fanfiction could be about Wanda Maximoff's untapped powers during Infinity War. Maybe she discovers a new way to use her chaos magic that could have changed the outcome of the battle. For example, she might find a way to reverse Thanos' snap before it even happens.
