This week, as my life still revolves around Kingdom Hearts, and after a conversation with marsy, in which we determined that there are very few characters originating from Kingdom Hearts, that are not in some way, shape, or form, arguably another character in the series, due to how connected they are, be it through possession or otherwise, I’ll be trying my best to explain, simply, the connections between these characters. Please be aware this will contain spoilers, and also before I begin, as far as I can determine, throughout the seven games in the series, there are only five named characters who are not in anyway connected, through convolution, to another character.
Characters connected to Sora:
Roxas is Sora’s Nobody, and Xion is his clone. Ventus’ heart is inside Sora, which is why Roxas looks like him, it is also very implied that Roxas has Ventus’ heart. Vanitus is the darkness from Ventus’ heart made manifest, and he looks like Sora due to an earlier connection between Ventus and Sora’s hearts. Naminé is also arguably Sora, as she was created by Kairi’s heart leaving Sora’s body.
Characters connected to Xehanort:
Xehanort (Ansem the Wise’s Apprentice)
Ansem, Seeker of Darkness
Master Xehanort is the original Xehanort, who possesses Terra, they then lose their memories and become the apprentice Xehanort. Upon regaining his memories as Master Xehanort, he split himself into a Heartless, Ansem, Seeker of Darkness, and Nobody, Xemnas. Ansem, SoD, then travels back in time and grants the power of time-travel to a younger version of Master Xehanort, who becomes known Young Xehanort. Ansem, SoD, also later possesses Riku, and while he is subdued, it meant that Riku temporarily took the form of Ansem, SoD, after using the powers of darkness. Xigbar and Saïx are both members of the true Organisation XIII, meaning that are vessels for Xehanort, and possess a fragment of his heart.
Nobodies and their Somebodies:
Aside from those with other connections, mentioned previously, these are fairly simple, as they are just alternative versions of each other, depending on whether they have their heart or not, though some have differing personalities. Those with ??? are characters whose somebody is not known at this point in time, and while it is unknown whether they will be introduced or not I am hesitant to declare them as having no connections.
Other connections of note:
Riku Replica: Riku’s clone, only present in Chain of Memories.
Ansem the Wise: Has his identity stolen by Xehanort, assumes the identity DiZ, later returns to being Ansem.
Xion: Looks like Kairi as she was Sora’s strongest memory.
Characters without Connections:
Thanks for reading, this turned out longer than expected, Kingdom Hearts is even more convoluted than I assumed, and I fear it’s only going to get more so, since time travel has become a thing, though I’m still looking forward to Kingdom Hearts III, hopefully it will get a release date soon. Anyway thanks once again for reading, and I hope this made some sense.
