I think color hates being and feeling lied to. in the past I do think he’d have a tendency towards boundary pushing and fishing for information whenever he feels like he’s being lied to.
sometimes he was actually being lied to, sometimes he was being paranoid in response to his sensitivity towards signs of dishonesty and rejection or abandonment, but sometimes he was never being lied to—it was just something he didn’t and never needed to know because it never had anything to do with him.
Thinking about Killer doing everything he can to make Color laugh. He's addicted to the sound, some part of him actually feels good and appreciated and wanted whenever he hears it. Making Color laugh is always an option on the table whenever he gets bored, and knowing Killer he'll go to extremes wildly out of range to keep that flow.
He will purposefully act stupid just to get a giggle out of this man, and he will participate with members of the Epic Sanses and The Abyss Team for the sake of humor. If Dust and Horror are around too, he'll drag them into these jests.
Epic, I think, would be the most receptive to Killer's mission and they wouldn't even have to talk about it. Epic just picks up on the hints and goes along with the most random shit, sometimes including Cross on these collaborations too if he so happens to be present (poor guy).
Choosing which Sans au has prefers sweets (has a sweet tooth) or prefers spicy or bitter food | Chromatic Crew (-Killer) and Abyss team (Murder time trio ver)
Keep in mind that I'm not familiar with abyss team so my opinion might change after I'll get to know them better.
Chromatic crew:
Epic - I think he enjoys both sweet and spicy food (bitter? Not so much) but if he had to choose between sweets and spice then he'll choose sweetsm
Delta - ironically (I guess), sweet tooth. This guy would prefer a sweet drink over beer
Color - prefers spicy stuff. He does enjoy sweet stuff but he rarely eats it. He enjoys dark chocolate
Cross - I don't think he has a preference. I think he enjoys both, sweet, spicy and bitter food.
Abyss team (-Color and Cross)
Abyss - sweet tooth. To me, he looks like a guy who'd eat kilograms of sweets and be fine and happy afterwards
V - spicy stuff. Maybe. Don't know much about this guy.
Beats - they have a sweet tooth to me! I think they'd like gummies in different shapes (like stars, bears and etc)
Kin - also ironically (maybe?), sweet tooth as well!
Mecha - again, I don't know much about this guy just like V, but, mm, let's say it will enjoy bitter stuff. And spicy too! I think it wouldn't mind eating any of sweet tooth, too
Ganz - Spicy stuff. I think he'd have a great spice tolerance, bigger than Color's (who I already headcanon to have a big spice tolerance). I don't think he'd enjoy sweet stuff, though... (and here's the difference between him and Mel, despite Mel being his alter ego. Mel, though, just like Ganz enjoys spicy stuff, he also enjoys sweets! )
Undercover is an Undertale Au that takes inspiration from Emily Crystal's IE Au, Lunnar-Chan's Emperor au (I believe that's what it's called, I don't actually know much about that Au, I just like the designs). As well a weird ass dream I had.
The name of the world this story takes place in is called Celestial (I really couldn't come up with anything better). Sun's Empire is known as the Astral Empire.
Celestial University is a school that is both a high school and college mixed into one. The university is fairly new, only being established after a few years after Echo's biological parents had passed, his old home castle being repurposed and becoming the school.
The parents/adults are unaware that the ship children are spying on Nightmare
