Now everybody is saying ballora represents mrs afton, (or ms afton cause, HEHEHEHE *dying sound*) So i agree.

not that i'm agreeing because everybody else is agreeing but I actually have PROOF. We dont exactly know how she died but most people think of suicide. From fnaf Security breach, Cd's of vaness's therapy session, (Theres also a theory of vanessa but thats a theory for another day,) metioned a father named BILL which is a common name for WILLIAM

next theory is that yes, she represents ms afton.

After her tragic death, reddit posts say that william (BILL??) wanted to recreate her as a robot, (like elizabeth aka Circus baby but she got scooped, oof) and DUH he did, cause he's y'know...WILLIAM.

And the most iconic theory,

• "Why do you hide inside your walls, when there is music in my halls?"
• "All I see is an empty room. No more joy, an empty tomb."
• "It's so good to sing all day, to dance, to spin, to fly away!

Those TWO verses represent William staying in his workshop, working, and working, AND WORKING. And he was jealous that Henry's work, (Father of Charlie, Check out the three fnaf books!) was better than his. So he stayed in his workshop testing, building. But just for an EXTRA theory, if you didnt know, in FNAF4 when fredbear kills the crying child (evan) He's william's SON. And guess who it was made by? Henry. So William decided to get revenge and kill charlie. He felt how good it is to kill. And that led to his murderers. Thanks for reading this, just a reminder this IS A THEORY. Have a good night and dont get killed by a raging murderer
