SPAMTON G SPAMTON and JEVIL are silly goofy funny scrunkly scrimblo boingo boinglos but are also very fucked up!
I think everyone understands that these two have connections to our reality-shattered fellow, W. D. Gaster, but i want to say that these connections go further than just caps and actually knowing him.
[ This "Theory" is mostly a compilation of wild ramblings that i am trying to make sense of, so sorry if it's not good ]
Question 1: What the hell are Spamton and Jevil
Spamton and Jevil are the Secret Bosses of deltarune. Their defining traits are;
1. Speaking in all caps
2. Spouting seemingly incomprehensible noises
3. Always Smiling, even when in pain
4. Mostly Black attire
I want to put emphasis on the third trait. In general, the colors are laid out as;
-Light-colored face
-Black attire
- a collar/neckpiece
This works with both Jevil and Spamton, as in Jevil's case his body is covered with a black coat, and he is wearing a brightly-colored Ruff on his neck, whereas spamton straight up copies Gaster for his design.
Question 3: What ARE the Shadow Crystals?
the shadow crystals are a key item, dropped by Jevil and Spamton (which i will call ShadowBosses from now on), that allow you to see through the darkness. In light world, they are just pieces of glass.
Crystals can be made by shattering a piece of glass.
And Gaster is specifically rumoured to be "Shattered across time and space", so... What if ShadowCrystals are pieces of Gaster?
His insanity, his knowledge, channeled through the crystal and to the ShadowBosses. They cannot control what is more powerful than them, so they go insane.
Question 4: Have you heard of UNDERTALE?
Hear me out. In Undertale, the enemy Memoryhead, that has the ability to give the player a "Bad Memory" item. You cannot get rid of the Bad Memory. You can only lock it away. Hide it. Ignore it.
What if the ShadowBosses are Bad Memories? Hidden away, yet their existence runs through the dark world. They are strong, they hurt a lot. Jevil, forgotten by the Kingdom, yet feared by those who remember, or Spamton, a seemingly-irrelevant character, but slowly unveils the darker, yet darker insanity behind it. They are hard to deal with, but once you defeat them.... You are granted a piece of something much, much bigger, something you cannot get rid of.
