In Archer and Saber fanfiction, Archer's time travel can be a really interesting concept. It might allow him to change certain events in the story. Maybe he could use his time - traveling ability to prevent some tragedies from happening to Saber. For example, he could go back in time to before a battle where Saber was almost defeated and help her strategize better.
His time travel can also introduce new characters or storylines. Maybe he travels to a time when a powerful mage existed who could help Saber in her journey. By bringing this character into the present (or past, depending on how the time travel works), it would add a new element to the plot and create new relationships and conflicts. Another way it affects the plot is by changing Archer's own character development. Through seeing different versions of Saber in different times, he might grow and change in ways that wouldn't have happened without the time travel.
Archer can potentially be a comic. It could feature characters and storylines in a comic format if someone decides to develop it that way. But it might not be a mainstream or widely known comic as of now.
Yes, Archer has its roots in a comic. The creators drew upon the comic's elements to create the animated series, maintaining certain core concepts while adding their own twists and expansions.
The book,"Quick Crossing: Cannon Fodder Scum Torturing Journey", might fit the information you provided. In the novel, the female protagonist traveled to various worlds. Sometimes, she was wearing clothes, and sometimes, her soul traveled. Perhaps this is the plot where the female lead's soul is lost in a car accident that you mentioned. I hope you like this fairy's recommendation. Muah ~😗
Well, in such a fanfic, perhaps Archer sacrifices his arm while saving Arturia from a great danger. Maybe it could be a powerful enemy attack and Archer jumps in the way, taking the brunt of it on his arm to protect Arturia. This would be a very heroic and selfless act on Archer's part.
