Massive spoilers for UNDERTALE, if you haven't played it, go do it!

A thought has been going on in my mind ever since I got into Undertale. Ever since looking at the theories, I've been trying to piece things together and an epiphany struck in my mind. I believe that, instead of Frisk, you, as a player, are the embodiment of Chara to begin with.

You name the "Fallen Human", supposedly to be Frisk, but at the end of the Genocide run it is all revealed:

Chara's "determination" and "human soul" apparently belongs belongs to Frisk.

You know Frisk is the 8th fallen human because Flowey asks if they're new to the underground at the start of the game, and is being mistaken for Chara because they look so similar to eachother.

The only small differences are the colours of the clothes they wear, their hair style...
In fact, they look completely different in terms of appearance, because even the hairstyles are different.

In the end of the Pacifist ending, Flowey tells you that someone still has the ability to reset everything: You. He doesn't associate you with Frisk, but as a player.

You've been controlling Frisk, and apparently, so has Chara.

That smiling sprite at the end of the Genocide run may turn out to be the reflection of your consequences.

Chances are, I believe you'll still think Frisk is Chara because of the end of the Genocide run, when you kill Asgore, Flowey claims that he's "your best friend", much like when he became Asriel in the Pacifist ending.

However, Chara had been dead the whole time. Flowey doesn't know it's Frisk this time, because at the end of the Pacifist run, if you choose to reset everything, you reset everything. Including Flowey's memories. He had lost all awareness of who Frisk was, and now just thinks of them as a new human who fell into the underground.

Once again, Chara has been dead this whole time. It wasn't them actually being controlled in the run, it was Frisk, of which was supposedly possessed by the spirit of the first fallen child to begin with. However, if they were possessed, they would be out of your own control. You, Chara, have the ability to reset the timeline.

And finally, what is the last thing Flowey says at the end of his Pacifist run speech? "See ya' later... Chara." However, you can replace "Chara" with any name you want. Because you're the one naming the child.


There are probably countless flaws in this theory, but what do you think? Lemme know in the comments.
