* In ''Comicbook/TheFlashInfiniteFrontier'', Wally West's wife Linda is writing a novel. In the 2022 Annual, it turns out to be a science-fiction romance about an Asian-American journalist who gets swept off her feet by a red-haired space hero named Billy East. He doesn't actually have superspeed, but he does have a jetpack. The crew of his spaceship includes the icy commanding officer Leo (Leonard Snart, but probably more based on his heroic future counterpart Commander Cold) and the comms officer Rathaway (Hartley Rathaway/The Pied Piper). The villain is Ka-Dabra (Abra Kadabra), the richest man in the galaxy, who attacks them with a computer virus called Gore-K%ll (Kilg%re) and a giant space cobra (a sideways reference to Kobra).
