In certain comic universes, the Speed Force has faced significant events that could be interpreted as its 'death'. However, comic storylines are complex and can vary greatly.
Ruby would be a likely candidate. She's already known for her speed and agility in combat. If she were to be affected by the Speed Force, it would enhance her existing abilities to a whole new level. She could move so fast that she becomes almost invisible to her enemies, and her scythe attacks would be even more deadly with the added momentum.
Peter Parker in the context of the Speed Force could be really interesting. The Speed Force is often associated with speedsters like The Flash. If Peter Parker were to be connected to it, perhaps he could gain super - speed in addition to his spider - powers. This could make him even more formidable in fighting crime in New York. He could use his speed to quickly web up villains or reach the scene of a crime in an instant.
The Speed Force in Young Justice fanfiction can also be a source of conflict. Maybe the Speed Force starts acting erratically and causing problems in the world. The Young Justice team has to figure out what's wrong with it. Is it being manipulated by a villain? Or is it a natural imbalance? This could lead to a complex and exciting storyline as they search for answers and try to restore the Speed Force to its normal state.
In certain comic arcs, Barry takes actions that lead to the destruction of the Speed Force. This often has significant consequences for his powers and the superhero universe.
Yes. In some fanfictions, authors like to create crossovers between different universes. So, Harry Potter could be integrated into the Speed Force concept, which is really creative and gives a whole new perspective to the character.
