Alternative Dust!UnDtale Timeline

so basically Dust!UnDtale but in the style of Alternate Dust!Determinatale!Sans Timeline

Story
Alt was fighting the human like usual until he starts to feel something weird. Then he realized his DT is gone so he teleported to the lab but since Frisk was already there and then punched Sans off the lab and since Sans lost his DT he fell into the lava and died forever his last words were "I guess I'm really a failure I'm sorry I failed you all I hope you can forgive me". Frisk was going to reset until the Phantoms of Chara and Papyrus and Blaze were about to fade away until they managed to launch Frisk into the core but unlike Gaster. Frisk didn't get Shattered frisk got erased from existence in that timeline.

information
This will not happen in Alternate Dust!Dtale timeline since Sans has way too much DT even if it did Sans could just grab some more well it depends if it's still there is
