Determination

SOUL trait
Determination itself is a hard thing to explain, because it covers most of everything about TrioTale and most other AU's out there. From the Undertale wiki, it explains that it is the will to keep people alive and persist after death.

Powers
People with Determination Souls can "refuse" death, but they can only do it so many times before they will actually die. The being with the most Determination can Load and Save the timeline, or even RESET back to when they gained the ability.(it seems contact with the monster magic in the Underground is needed to activate the ability, as all known users were only able to use it after falling).

Known owners

 * Chara Dreemurr
 * Cube and all other AU versions of him
 * Void!Frisk
