What if Riviera characters were in Brawl?, You have no time to ponder such questions, as Ledah has just grabbed a Options

If Riviera characters were in the game, here's how I would see them working. Each character (Ein, Ledah, Lina, Fia, Serene, and Cierra) get movesets that reflect their primary weapons. Their special (B) moves are dictated by their Overdrives (one or two may be omitted a result) while their Final Smash is their final weapon's Overdrive.

I don't see any of their Final Smashes warranting an OHKO, however. The only EXL Overdrives are Ein's Disaresta, Ledah's Lost Seraph, and Fia's Banishment. Going by Brawl itself, the only real OHKO is Marth's Critical Hit. Some Final Smashes have excellent ringout potential, like Mario Finale, while others are immersed in power and the potential to ring the enemy out quickly, like Super Sonic. Then we have Link, Toon Link, and Ike using sword combos that can result in an OHKO, but aren't guaranteed, like Marth's. It's this category that I see the Riviera characters falling in. Obviously, they use weapons, so it would be logical that they would follow their Final Smashes with their weapon animations.

Regarding a stage I definitely see Heaven's Gate as the primary stage. Chains, layers, and falling off would make a large stage, even comparable to Hyrule Temple. Traps such as false floors that crumble would make an ideal obstacle and the stage could have several themes like "Heaven's Gate", "Encounter", "Battle Against the Devil Tribe", and "Fierce Fighting" in the My Music section.

Finally, Serene would be able to float, Lina and Fia would be the fastest, Ledah would be the strongest, Ein would be the most balanced, and Cierra would be the heaviest. Guess why?
