* FanNickname: Due to Nezha's resemblance in personality, his nickname is "Tron Hui".
* TheOtherDarrin - Due to the voice actors used for Dynasty Warriors 5 and Samurai Warrior 2 being from different companies (Voice Group and Agile Sound respectively), the Samurai Warriors characters had to be recasted with Voice Group [=VAs=].
** For both Fu Xi and Nuwa, their previous Japanese voice actors in ''Dynasty Warriors'', Creator/KenjiNojima and Yuuko Sumitomo were respectively replaced by Creator/HirokiYasumoto and Yuki Makishima.
* PostScriptSeason: Debatable whether or not it was planned from the start, but even though ''3'' was touted as being the final game in the series and thus the Hydra plotline being the GrandFinale, the plot was extended by four more chapters in ''3 Ultimate'', introduces a new villain which takes center stage after the Good Ending, and also provides some more backstory on the Mystics.
* RelationshipVoiceActor - Gracia and Sima Yi can have special relationship in the third game. Both are voiced by real-life married couple, Jun Shikano and the late Tsuyoshi Takishita, respectively.
* TalkingToHimself: Happens constantly with some of the characters who both share the same voice actor and have a bond with one another. Exemplified in the Japanese dub by Daqiao and Xiaoqiao, Jia Xu and Motonari Mori (who got a scenario where they interact a lot), Nene and Ayane, Motochika Chosokabe and Sima Shi, Nuwa and Kaguya, etc. However, while Achilles is voiced by [[Creator/NobutoshiCanna the same guy who voiced Cao Pi]], the two characters never share a scene together.
