2023’s The Flash actually introduced more than one love interest for Barry Allen. His first comic love Iris West returned to the film after her debut in 2021’s Zack Snyder’s Justice League while he also developed a unique connection with Kara Zor-El/Supergirl. While he isn’t as amorous as his successor Wally West, Barry Allen has still dated a few women over the years in the comics.
