What? What do you mean, Mystic

In fact, there is a specific ending that can only be achieved by hacking the game. And when we do so, Sans will call Frisk/Chara and say "I don't even know how you got this ending. I guess you're just a dirty cheater". Chara/Frisk is us, and we are them.

Ooooor Sans is directly speaking to player and not to character

Then it further is cemented, because all of Chara and Frisk's actions are the player's. Chara herself is the embodiment of the player, due to the name "Chara" being short for "Character".

Goku wouldn't be an easily win though.

LV isn't for strength. It stands for "Level of Violence" which Sans states is just a measurement of how comfortable someone is killing another person.

"Then it further is cemented, because all of Chara and Frisk's actions are the player's. Chara herself is the embodiment of the player, due to the name "Chara" being short for "Character"."

It's just your interpretation tho

It's not really my interpretation. I believe Toby Fox stated that he left everything about Frisk and Chara ambiguous so we could imprint ourselves on them. Or something like that. This is the reason why they have no canon gender, so they can logically be any gender. It's also why their pronouns are always "They or Them" since it can count for both genders.

Only players actions part is confirmed by Fox, everything else is your interpretation.
