One Piece: A Smash Adventure contains examples of:
- Back from the Dead: With the exception of Bowser and Giovanni, every single main villain (not exactly ALL of them) of a certain series was revived by Obscurum.
- Calling Your Attacks: Both the Straw Hats and the Smash Bros. characters do this, in the latter case even if they normally are Heroic Mimes (like Mario and Link) or can't even speak (like Pikachu, Ash does the calling for him in true Pokémon: The Series fashion). Named attacks are written in Upper Case.
- Final Battle: The Straw Hats VS. Obscurmentio, Dimentio's final form
- Free-Sample Plot Coupon: Merlon had the first mystery heart and gave it to the Straw Hats similar to how the Merlon in Super Paper Mario had the first Pure Heart.
- Multi-Mook Melee: The Straws Hats vs. the Fighting Alloy Team in the Smash Bros. arc.
- Original Character: The Emperor Gods as mentioned in the Smash Bros. arc and the Aterneco in the final arc
- Plot Coupon: The mystery hearts. In the same vein as Super Paper Mario, these eight mysterious artifacts created by Master Hand are the key to properly access the Smash world and are placed in safe locations in eight worlds to make them difficult to find, but unlike the Pure Hearts each have a special look as opposed to being heart-shapped.
- Sliding Scale of Continuity: On the One Piece corner, the story is set after the Enies Lobby arc, so Brook is not in the crew and Zoro has no access to Shusui. In the case of the series represented in Smash, it's more varied: the Super Mario arc is set after Super Paper Mario and there's no mention of Super Mario Galaxy, the The Legend of Zelda arc is set after Twilight Princess, the Pokémon and Kirby arc heavily take elements from their anime continuities (Ash and Pikachu, Jessie, James and Meowth, and Brandon in his anime characterization in the former; Tiff and Tuff from Kirby: Right Back at Ya!! in the latter), to name a few examples.
- Trapped in Another World: The premise of the plot. A malfunctioning Master door to the Smash world absorbs the Straw Hat Pirates and sends them in the Mushroom Kingdom, and to return to their own world, Luffy and his crew must gather the eight mystery hearts scattered in different worlds (similar to Super Paper Mario), setting on a journey encompassing locations such as Hyrule, the Pokémon World, Pop Star, and the Smash world.
