(Y/N used to be the captain of Hyperion, and dated several valkyries until he caught them straddling other guys' waists, much to his shock and anger.)
Kiana: Please, Y/N! It's not what it seems!
Y/N: SERIOUSLY?
Mei: Y/N, please...
Y/N: Really!?
(They didn't say anything she just stood there looking down at the floor.)
Y/N: (coldly) I've made my decision. I hope you enjoy being single!
(With a heavy heart, Y/N strips off his captain's insignia and exits, leaving behind whispers and tearful pleas.)
(In the streets, Y/N walks with his FAMILY, laughing and unaware of the lurking danger. Suddenly, a villain emerges, attacking them. Y/N fights valiantly but is overpowered. His family falls victim to the chaos.)
Y/N: (desperate) No! This can't be happening!
(Y/N's grief triggers a transformation. His body morphs, and he becomes ASH-GRENINJA, a being of immense power. He swiftly defeats the villain.)
Ash-Greninja: (glares) You're finished, villain.
(Then the officers approach the villain.)
Officer: (glares at the villain) You're under arrest!
(As the villain is arrested, he tries to convince the officers that he saw a frog-like ninja, but they didn't buy it, and the villain got taken away. As for Y/N, he is seen overlooking the city at the top of a building.)
Ash-Greninja: (resolute) From this day forth, I will protect the innocent. This power... it's not a curse, but a responsibility.
(Y/N, now Ash-Greninja, is seen taking down several villains as he uses one of his moves.)
(The water shuriken slices the villains in half, but he already knows that his ex-girlfriends are chasing after him.)
Ash-Greninja: They may chase me, but my path is clear. I am the shield in the shadows, the guardian of the innocent.
(Meanwhile, the valkyries are determined to get Y/N back.)
Bronya: (determined) We will find him. We must explain everything.
(Beneath them are the dead bodies of the random guys they cheated on Y/N with.)
(One fateful day, Y/N is seen patrolling the city as Ash-Greninja as the people he didn't want to see surround him.)
Ash-Greninja: Of all people I didn't want to see...
Fu Hua: Just listen to us.
Ash-Greninja: I guess I'm gonna have to make sure I'll never see you again!
(He then prepares to attack as he charges at Himeko.)
(As he knocks her out, he goes to face Seele, and...)
(He slashes her, and then the valkyries charge at him as he keeps on fighting.)
(He brings down the valkyries as they struggle to get up.)
Himeko: (grunts) Damn, he's pretty tough...
(Kiana sees a slash on her right cheek.)
Kiana: You're coming back to us, captain... (yandere tone) WHETHER YOU LIKE IT OR NOT!
(She then transforms into the Herrscher of the Void, and then they have an epic clash as both are evenly matched.)
Ash-Greninja: (in mind) Okay... it's all or nothing!
(He then launches his Ultimate Shuriken at Kiana.)
(He thought it killed her, but then he gets blasted and loses consciousness.)
Y/N: (weakly) Ugh... damn it... ugh...
(He is then taken by the valkyries, and was no longer seen or heard of again.)
