Dante used the name Tony Redgrave as an alias in his early days of demon slaying. When asked about the name, director Hideki Kamiya stated that "Antonio Redgrave was a journalist that Dante respected, so he used it as his fake name during his days as a mercenary..." In Bayonetta, Luka's father, Antonio Redgrave, was a world famous journalist that documented supernatural events, people, and places. It's very likely that the two Tonys may be the same person.
