☽ ⋮ ✫ ━  ❛ serenity's connection to kingdom hearts.

the following canon is exclusive to this blog's kingdom hearts verse and doesn't apply to akari's main canon ( this post also contains spoilers for the live action sailor moon show so please read at your own discretion ).

in case you are reading this and aren’t familiar with it: there is a live action version of sailor moon, pretty guardian sailor moon ( or simply pgsm ). it expands on the dark kingdom arc a lot as well as the characters in a way most sailor moon canon - not even the 90s anime - doesn’t. anyway, princess serenity is hard-freaking-core in it unlike most versions of the character. when endymion dies, she is the one who is responsible for the destruction of the moon and earth kindgoms while in the present, she starts possessing / controlling usagi whenever she's upset, sad, etc. and when usagi has to kill mamoru? serenity possesses her and literally destroys the world ( again! ).

as a result of this, usagi constantly has to make sure she stays happy, positive, etc. so she isn’t literally possessed by her past self and i could imagine there’s a similar thing at play with kingdom hearts!usagi. there’s no possession or anything but she doesn’t wish to talk about her past as it only brings out a lot of negative emotions in her which isn’t helpful when she’s constantly battling to keep her emotions in check. she could very well destroy the universe if she where to ever grow too upset and enter a ‘berserker’ state. honestly, it’s probably one of the reasons she takes her own life because the combo of archisei leaving / possibly being dead and mamoru dying would be too much for her to handle. it would send her over the edge and she’s more than aware of what would happen as a result so she kills herself - both out of immense grief as well as not wanting to let the pain fully take over and do even more damage. 

in the manga, the 'lambda power' is a power accessed through the galaxy cauldron that pretty much resets all the star seeds / revives everyone and her having a similar power that is tied to kingdom hearts would make a lot of sense. it would be even more interesting if she is the hotaru / sailor saturn here: a being who only exists to usher in the universe’s destruction and rebirth should it be time to. her true purpose is masked by the fact that they give her a crown, fancy dresses, and people who spoil her / attend to her every need in order for her to remain ‘happy’. however, serenity basically only exists to wait until the rest of the universe gets completely swallowed by darkness before she steps in to destroy and reset everything - a process that would kill her too!

this all ties into why every serenity is locked away in the first place. she has a powerful and extremely dangerous power within herself. even when the current serenity got to go out and train she was basically under surveillance by her guardians at all times. she’s probably not even supposed to have close connections with others outside of her mother and guardians because strong relationships = strong emotions which is bad. she was never supposed to get marred or conceive a child since each serenity is essentially just a clone that is well groomed to know and accept nothing but their ‘place’ and not going outside their station.

her power is drawn directly from kingdom hearts or the silver crystal ( which is the keychain on her keyblade ) but the former is a far stronger power source. she will harm, even kill, anyone who should get in her way and depending on what exactly triggers her berserk button, serenity could appear as a tranquil fury or an unstoppable rage. if the moon kingdom is the last world to not be taken by darkness then it is her sworn duty to use the maboroshi no shirubāchēn to reset the universe. during that moment, she isn’t aggressively rampaging here and is in more of a peaceful, trance-like state as she has only one, singular purpose while in this form: to summon kingdom hearts. should she become so angry, so consumed with grief, or any other highly negative emotion, it’s possible that her feelings could awaken the crystals power ( which is dangerous in and of itself ) and legitimately cause her to rage out.

should a serenity ever enter her berserk state this way and cannot be talked down then it’s the leader of the queen’s guard, sailor venus, duty to strike her down before she can destroy the world.
