So time for another random thought. Someday I'd like to see either the Wave Blades or the Grieve Edge come back from III. Maybe combined? That'd be one slashy mess of a character to look at with blades around their arms and sticking out of their feet, but it might be fun.
I could actually see this working, that one flippy attack of the Wave Swords being able to have the Grieve Edges deliver a follow-up, and just in general, giving the arms something to do with the Grieve Edge style... It would be a wall of blades.
I'm kind of tempted to boot up III and help fuel my imagination. I'd be surprised if the Wave Edge style ever happened (Grieve Blades? Whatever sounds cooler), but it's fun to think about. It can be part of my dream season pass alongside Soul of Kazuya.
Without meaning offense, I honestly can't think of something that would more quickly undercut everything that made special a particular style that already has a great aesthetic and sense of weight and balance. I would say two such styles, but the truth is, I find the Wave Sword style to be among the more gimicky, contrived, and goofy of all of the SCIII:CE bonus character semi-styles. Grieve Edge, on the other hand, is brilliant, and deserves to come back in its own right, with an expanded moveset without being chained to one of SCIII's most impractical weapons (which is really, really saying something). Grieve Edge both
took inspiration from* and
gave inspiration to genius. What you two are contemplating here sounds unlikely to be a fraction as inspired as the original approach to the concept, if it could even be made cohesive at all without degenerating into a noise of flailing limbs and Dampierre-level silliness. Sometimes more quickly becomes less, my friends. All Grieve edge needs is expanded moves, maybe a little bit of fusion with a brawler vibe.
* Actually, the first of those links actually comes from a movie that post-dates SCIII as well, but is part of a continuity in Hong Kong action films: it just happens to be the best one, and the one closest to Grieve Edge, so I chose it to represent the concept in live action film. Monty Oum's take on the weapon is if anything even more nuanced, and clearly influenced by Grieve Edge (long time fans of Monty's work will know he must have been a big fan of Soulcalibur, since its fingerprints were all over his Dead Fantasy and RWBY character designs and fight choreography, though his work was a synthesis of a broad range of action and martial arts forms, both real and fantastical, filtered through his own unique brilliance.
