I didn't know that, and I read several issues of that comic when I was a kid. I never read much Lone Wolf and Cub, but I recognised them in Shogun Assassin.
The
Valérian-
Fifth Element connection is an excellent example of feedback between comics and films. Besson's a huge
Valérian fan, so he hired Mézières to do some design work on
The Fifth Element. The movie was a dream project of Besson's, one he'd been wanting to do since he was young, and when he had the chance to work with two of France's leading comic book artists, he hired them to do the film's concept and design work.
As Jean Giraud (better known as Moebius) said in an interview: “When Luc Besson did
The Fifth Element, he went back to a story he’d written as a child under the influence of comic strips. He wanted to pay tribute to the work of Jean-Claude Mézières and Moebius, and so he decided to use us both as production designers. It was a bit of an homage, and at the same time, a very touching gift from a reader. In a way, you could say it was a very Moebiusian moment.”
The Incal, the classic science fiction collaboration between Alejandro Jodorowsky and Moebius, was one influence on the film. But the New York scenes...
Mézières did some preliminary design work for Besson in the early 1990s, but the project's funding fell through, so Mézières incorporated some of the material he'd designed for the film into
Valérian's fifteenth album. (After all, the film might never get off the ground, and cool ideas are cool ideas...)
When Besson got funding for
The Fifth Element, the writer/director changed some parts of the script based on what he'd liked about
Les Cercles du Pouvoir-- the aforementioned fifteenth album-- altering the screenplay to emphasize design aspects originally done for the film, but which were now a part of the comics' narrative universe. And certain things from the fifteenth volume of the comic wound up influencing the direction the film took. Besson
really liked the stuff in the album about a supporting character, S'Traks the taxi driver. Pierre Christin and Mézières,
Valérian's creative team, had fallen in love with the idea of futuristic taxicabs. Besson originally had thought that
The Fifth Element's characters should travel around New York by riding a kind of elevated train. When Besson saw what Mézières had done in the comic with the taxi designs, which the director had contemplated using as part of the movie's background visuals, he got to thinking... So taxis became central to the plot, and the director got Mézières to do a few further designs for the movie...
Valérian's impact on
The Fifth Element was so extensive that some of the movie's shots actually reproduce or visually quote panels from
Les Cercles du Pouvoir; this is particularly true in the film's New York scenes.
(A translated version of
The Circle of Power, the fifteenth volume in the ongoing
Valérian saga, is available Stateside in
The New Future Trilogy.)
The
Valérian comic's been going for almost forty years-- it started as a serialized comic in the 1960s-- and Valérian and Laureline are still having adventures...
EDIT: If anyone's interested, some text (in French; the interview covers some of the same ground as the above post) about the relationship between the comic and the film, some panels from
Valérian, and several production sketches for
The Fifth Element can be found at the official homepage of Jean-Claude Mézières:

(Notice that panels from the
Valérian album are used to illustrate the artist's comments about the taxi; click on "Galerie" for more
Fifth Element design work.)
