"Speedsters are boring, they're useless they just run fast."
Wrong!
Jay Garrick can make sonic bombs by just hitting his helmet at the right frequency. Barry Allen can disassemble and reassemble himself molecule by molecule at will. Wally West can freeze a person in time by removing their potential kinetic energy. Bart Allen can trap entities between molecules. Eobard Thawne can age someone to dust with a touch. Literally any of them can throw a grain of sand with enough force to go through any armor you care to imagine. Speedster abilities are not only endlessly creative, they're horrifyingly OP.
i can’t stop being plagued by thoughts of bart allen. can you. can you imagine being fourteen years old and waking up every day knowing that your loved ones will always be beyond your reach? that you have family who are alive and well but you’ll never see them again? that there isn’t just physical distance between you and your mom but hundreds of years? that no matter how much family you have in this time, no matter how much they love you, you’ll never be whole? you will never have everyone you love in one room? that not one single person in the world speaks your native language? that your mom wants you and loves you desperately and you still can’t be with her? that you can never go home?
