Barry Allen's death in the comics is a complex situation. Sometimes he does die, but often there are plot twists and resurrections as part of the ongoing comic narrative. It all depends on the creative direction of the writers and the demands of the story at that time.
In certain comic versions, Barry Allen is indeed identified as Jewish. This aspect is sometimes incorporated into his character background and story arcs.
Fanfic about Barry Allen and Savitar usually plays with their powers. Barry's super - speed is well - known, and Savitar also has this ability. Writers in fanfic might create scenarios where they race or use their speed in different ways. It could be a showdown of who is faster or how they use their speed to outwit each other.
Another great one is 'The Trial of The Flash'. This story puts Barry through a lot of moral and ethical challenges as he faces trial for the murder of the Reverse - Flash. It's a story that really tests Barry as a character and shows different aspects of his personality.
One of the best Barry Allen stories is 'Flashpoint'. In this story, Barry goes back in time to save his mother, which has a huge impact on the entire DC universe, changing the relationships and nature of many characters.
