No characters, no eight resolutions. Resolution is the ability of undertale players to save and read files (S/L) in the game, and it is a powerful force contained in the human soul. There is a very widespread misunderstanding in the underground world that the human soul is called "determination", but the former is the soul and the latter is the power contained in the soul.

In the game, "determination" usually appears in the form of yellow flash (save point), which can reply to the protagonist's HP and save the game data so that the player can return to the latest archive when restarting the game or dying.

Extended data

In the game, under certain conditions, Flowey will also introduce the meaning of "determination" at the exit of the ruins, which also implies that Flowey also has determination. At the end of the first neutral route, Flowey will absorb six human souls to become Omega Flowey and seize the player's file, which proves that the strength of determination can affect the ownership of the file.

"Determination" is a powerful force unique to the human soul, but monsters in extreme cases can also produce "determination" on their own.

After the blood volume of the neutral route Undyne returns to zero, Undyne will persist for a period of time (because the body can't hold too much "determination") and melt and die.
