Why does Sans bleed? - Undertale Theory

Why does Sans bleed? Is it because he’s a human? Is it because he’s from Deltarune? Is the red stuff ketchup? Or is it determination?

I don’t know, why does he bleed? Don’t ask me, you are the theorist.

[SweetStoneArts]

I thought "ketchup theory" was just a bunch of ketchup bottles and tape.

Slam dunk theory, I know

some weird or extra points for certain theories because i felt like it:

blood/bone marrow theory:
- monsters are MOSTLY made of magic, not fully. so why can't they have biological blood on rare occasions? (could even be the same in deltarune, only some have it?)
- it could also be that skeleton monsters simulate what a human skeleton would be, given the sheer resemblance (except for the skulls) so bone marrow and therefore blood would be simulated even if not needed.
- hell, it could just also be magical just like the rest of him, fake blood, if you will.
- as for why papyrus "doesn't bleed", it could just be hidden under his armour / not lit enough to see clearly under the armour. (battle body)

determination theory:
- given determination's connection to the color yellow, maybe his yellow eye is from that, with cyan for blue magic or something (idk, but i just thought it was neat).
- sans doesn't act very determined indeed, maybe the whole reason he even tries fighting you at all is because of some extra DT he injected? ("forced" determination if you will)
- DT might be red but the powers and magic behind it are yellow, thus the save point and such. (maybe even your HP is determination because its yellow, and it doesn't drop to zero when you "refuse").
- flowey probably has his determination in his roots, given that the roots absorb nutriens and water. (and thus maybe he was injected there?)
- i believe we never made undyne bleed because she didn't have any outer/visible wounds throughout the entire fight, she just melts and seemed fine for the rest of it. (armour shade again for neutral kills and before her undying fight)
even though people like toriel and papyrus get a bit of dialouge after they get killed, sans also just kinda walks it off for a bit before dying. like hes refusing to die just a little longer.

ketchup theory:
- it may have never been monster food at all, maybe just surface ketchup that got into the dump, or grillbs has a huge stash of it from god knows where.
- he probably has set this up for a long time, just waiting for opportunity to use this as a prank and/or a guilt trip like mentioned here.
- funny for the funny bone man.

also-
"SANS! WHY IS YOUR JACKET FULL OF KETCHUP STAINS?!" "its the new fashion trend, maybe you should ketch-up with the times."

7:00 you also have to consider that this monster child probably learned about blood from their aformentioned mother, who (as an adult) would know what humans and monsters are made of. However, one thing that I noticed is that the child says "made of" blood. Humans do have a lot of blood in them, but it's only about 10%. Maybe monsters have some blood too, but they don't need as much to stay alive. So, the child would be saying "you have a lot more blood than we do, does it hurt?". As for lancer, I dunno. I think it really is just a throwaway joke, and Toby messed up.

20:06 we aren’t the soul of determination, we are the soul of “ball game.”

[evanlephrog]

I bet Sans wears an emergency bottle of ketchup in his shirt incase he gets hungry.

[Lagw]

Reminder ya'll that Papyrus doesn't know what a sun is, yet he knows green grass

[fashikomeiji]

Theres another problem with ketchup, which it comes out of his mouth.

And it takes longer than the chest "blood".

And his mouth never moves so its weird to say he *bites* down on it, but then again, he has to eat for energy.
-
But its kind of funny how the "blood" is such a mystery,
Sans has so many ties to places that it could literally be so many things, but each thing has alot of flaws.

[TaskMaster]

Guys? The "blueprints" in the secret room in Sans' and Papyrus' house looks exactly like Susie's and Lancer's table where Kris and Ralsei make the Trash Machine.

[CuantumQ]

Sans could've met Alphys pretty easily. He seems to hangout throughout the entire underground in the game- though if you want to ignore that since he might just be following Frisk- he is confirmed to be a semi-regular comedian at MTT Resort, so not only would he go to Hotland often, but he also have potential ties to Mettaton and through him Alphys.
I think that Sans probably does do science with Alphys, I just wanted to give a potential reason beside it

[AFigmentOfYourImagination]

"sans has strong ties to gaster, and ketchup"
*explodes and then goes to ad*
best transition ever

[IamSans_]

Something you may want to take into account as to why people believe sans doesn’t die at the end of his fight isn’t just the end of battle sound that plays at the end that doesn’t only represent a monster’s death but rather the end of a fight. But what people should take into account is the number of kills you have before and after fighting sans that can appear in the entire menu thing you go to equip items and where your stats are located. After the end of the fight the number of monsters you have killed will remain the same. Also you could make the argument that LV increases the more you distance yourself from your soul rather than killing a monster, killing just makes it easier to distance yourself which is why our LOVE doesn’t increase each time we kill a monster but rather at certain times like how undyne gives us a load of LV or mettaton neo despite being a one hit. It’s more connected emotion wise rather than video game you leveled up mechanic. Sans said it best himself, EXP is execution points and LOV is Level of violence. Sorry for the rant just thought it could interest you, cool video btw

the brain rot of hearing the word "yellow" in an undertale analysis video is so insane lmfaoooo

Undertale: Random misaligned pixel in a random area

[imgolds]

Ketchup, is at least what I thought for a long time

[littleminer]

I feel like the logic at 0:43 doesn't quite make a whole lot of sense. The line specifically states that monsters are made of mostly magic, not entirely of magic (Alphys heavily implies that monsters have at least a little physicality in the true lab). Humans are made of mostly water, and they still have blood

The actual makeup of monsters probably varies a lot between each monster, like how Snowdrake literally says that they're made of ice post true pacifist, or how ghosts are clearly made of something special cuz they can just go through stuff. Maybe some of 'em just have blood, and that's that

[mintw]

My counter to the “sans ketchup is just fucking with you to make you lose determination” is that he has no reaction to you reloading after killing him beyond “wow youre fucked up”

[thatgibberishrappingdog]

way off topic but is the canonical reason why random food can save you from the brink of death because of the “monster food converting into energy instantly” thing

[FaultehBoi]

The ketchup theory has backups.

Maybe he had a ketchup bottle in his shirt so he could possibly survive the blow. It makes sense since he tries to stop us no matter what, so if he survived he could trick us and caught us off guard.
