Goku and the Z-Fighters: cannon strength
Chara/Frisk/Player (physical power): fat buu level
Chara/Frisk/Player (determination): just below Super Saiyan God Goku (BOG)
Sans (physical power): Majin Vegeta level
Sans (magical power): just above Super Saiyan God Goku (BOG)
Magical power is similar to the power of qi but different in some major ways. First while qi is channeled through the body magic is pulled from the soul, magic is much more versatile than qi since the source of the energy can be moved outside of the body. Remember the power levels will not stay like this but will make sense within the context of the story. I have a plan for how magic will influence the Z-Fighters, but if you have suggestions comment or PM me.
