JW!Altertale OST - Timespace Continuum

"Heya."
"It's me, Chara."
Plot twist, Chara is a goner! I decided to swap the thematics of the way Gaster and Asriel interact with timelines, cuz they swap in Altertale. Specifically, yours and the Gaster fragments' saves now work by being sort of between or outside timelines in a way, while Asriel sort of "slipped away from reality" by determination abuse, like he mentions in the canon fight.
And it makes sense that with all of Gaster's... ahem, experiments, and being in Asriel's role, Chara would end up affected by Gaster, and being a goner.
The SAVE functionality in game still functions the same, but the lore is different.
Also, Chara inherits Sans' "Heya" rather than Toriel's "Greetings".
This song has Megalo Strike Back due to an unused idea where Determination would replace the Megalo Strike Back motif in Asgore's Genocide battle theme, and then I changed Asgore's genocide battle theme so that no longer makes any sense. It's not Megalo Strike Back as Chara's theme, though I guess it can retroactively be interpreted as such.
And tbh, I feel like if MSB is used for anything in Deltarune, it would be the shenanigan involving Kris and the goner vessel, which is in a rather similar vein to this take on Chara, so it checks out anyway.
I always found the Altertale set of swaps to be interesting, and am disappointed at how poorly they're executed in the original AU.
Swaps:
- Chara stays in the same role, however:
- Gaster swaps with Asriel, meaning Chara's story is significantly different.
Leitmotifs:
Megalo Strike Back
This is not Undertale Last Breath Megalovania, nor is it an Enigmatic Encounter Piano Tutorial or a Star and Planet Size Comparison. It is an Altertale AU, which is an AU like Underswap, Storyshift.
