While the rivalry between Marvel and DC is largely among the fans, I'm incredibly excited to see one of the most underrated X-Men join the DCU to get a "redemption arc." Both Marvel and DC have released numerous projects over the decades, with varying degrees of success and popularity. While DC originally had a long spell of dominant theatrical releases, the 2000s began to see a shift for Marvel with the release of X-Men under Fox, and, of course, the MCU.
