Deltarune Secret Boss - Tumblr Posts
Same favourite character

can you guess who my favorite character is

drew these actually BEFORE the jevil drawing i did last post, thought they looked neat and didnt want them to go to waste.
i hope i'll get more people out there to try out drawing jevil in the same way people like to draw canon accurate spamton, that'd be cool, he's fun to draw tbh
My dumbass thought that was spamton at first



sinking realization
Secret Bosses
Heya I'm deciding to do a thing for secret bosses until Chapter 3 (hopefully chapter 3 doesn't release for a while) I'll try and show off a secret boss every day
Feel free to give me ideas and requests
And because of this format don't expect all of them to have a lot of details because some days I might not have time for that

Count Von Thrill!
A boss based on Micheal Jackson's Thriller (this was drawn in October btw)
He was a former musician who made a deal with the devil to be the top of the charts. So his fellow musicians banished him to hell. But now that he's back he's ready for one final grand tour and all he needs is a Lightner soul to stay in this realm and top the charts once again!
lDARKNESS FALLS ACROSS THE LAND

He replaces letters with numbers

Secret Boss 3
Meet E. Vile
A chapter 3 secret boss based on stereotypical villains

He's based on Papyrus and a wind-up robot and is a theater performer. However the script wrote him as a villain and so that's all he'll ever be. He wants to be free to right the script his way
He makes you collect pieces for his machine and he achieves his second form

In his second form he starts to embrace being the villain
If he's gonna be made out to be the villain then he may as well be the greatest villain there's ever been
His speech quirk is that he speaks as if it's a script so he says his name before all his lines and announces all his actions like most villains

Secret Boss 4....?

Seems everyone is making western show themed cowboy chapter 3 secret bosses
Someone should explain that to me in the comments but I know it has something to with Friend In Me
Is that a string of text in the code or a hint Toby Fox dropped? IDK
But I'm throwing my hat in the ring I guess
So here's Sheriff St⭐rry
He's the sheriff with a pull string and spinny head
He has the pink and yellow eye things and inside his belt is his little friend
Because of his pull string he randomly blurts out 20 different unique phrases and also he replaces A with ⭐ unless it's one of his aforementioned phrases
One thing people don't seem to realize is that Jevil and Spamton don't touch the ground in their respective fights (and I mean the actual secret fights) so this lil guy kicks his feet to stay afloat. He used to be the irl sheriff and lead actor of Starry's Roundup until he arrested a mysterious man accused of an unknown crime. He tried to talk to the man and something....strang happened....the man and the sheriff disappeared without a trace....seems the man told him of his inevitable replacement both in the show and as a sheriff...but that's show biz for ya...he was replaced by a younger techno sheriff.....
Something else happened to him it seems something he tried to hide all his life is trying to break free...his dark side....the feelings he repressed....and when he you repress your feelings for too long.....they tend to want to break free....
Oh and he uses blue soul cause Papyrus
Secret Boss 5....Right?

Another common trope for fan made Deltarune Secret Bosses is a corrupted Ice-E boss so here's Sl-Ice-E
An old animatronic for Ice-E pizza who use to serve pizza and smiles until a strange (kinda purplish black) man (strange guy really) approached and tampered with him
And he acted out and ate a child and got cancelled
He now what's be free of this alter ego
I saw this cool theory about Jevil representing ADHD and Spamton representing Autism so he represents DID having a disturbing alter ego inside his code
He uses pizza cutter blades as weapons and roller skates with pizza cutter wheels
He randomly adds hyphens into sentences because it's kinda funny yo
If you haven't gathered he's very FNAF but slightly colder
Secret Boss 7
Thx so much for the support rlly means a lot
All this posting on this account sadly means I haven't been updating my other account @deltaswap2442 enough but follow me there to help support that project
Either way here's what we came for
Secret Boss 7 Professor Koocoo

Professor KooCoo
A secret boss for the TV based chapter three based on educational television (no one really enjoys watching that shit) especially children's educational shows and not even the fun ones like Sesame Street
The boring ones
He's also a Coocoo clock here to teach you about: TIME
TIME ISH A TOOL YOU CUN PUTCH UN DA VALL OR VEAR IT UN YUR WRIZT
He has an over the top German accent because Coocoo clock
He also screams COOCOO COOCOO COOCOO every 12 sentences and also repeats words when frustrated and such
EINS ZWEI DREI DREI DREI DREI DREI! DREI! DREI!
To spare him you have to turn back the clocks so that the Coocoo bird goes back in the clock
Shorter description today but enjoy
Secret Bosses 8,9,&10
Sorry I haven't posted one of these fellas ina while but he's a few for ya

This is Fetti Widow a secret boss self insert I designed for my friend. She's a spider baker made of cake. She likes to make spider cupcake monsters and is a bit of a mad scientist. She killed her husband (fuck him). Oh and also she's at the center of the multiverse web forgot that kinda major detail. She's the plot device I use to allow my secret bosses to cross over. She runs a cafe/bar for them but is cursed with the inability to leave. So when everyone heads homes she's left there all by herself with her depression and thoughts. She's kinda like that cool grandma

Also here's some concept art I did for her and I had my friend pick her favorite. Shout out to Design F because it looks the most like a secret boss

But now more spiders. Mommy Longlegs is based on the Other Mother from Coraline. She has her doll form and then her fucked up form. She wants to make the world perfect like her family which she killed and replaced with dolls. Dolls don't break the rules, dolls don't talk back, dolls don't argue. She uses purple soul but with the ability to Parry. The purple soul works as spider web but also stitches

Lastly Cozmoze a star that once shined so brightly but soon his light faded compared to those around him. He began to spiral into the futility of it all questioning the point of it all. There are billions upon trillions of stars in the universe.....what makes you stand out. But then he turns into an Asriel God of Hyperdeath form and all hell breaks loose.
IM FINALLY THE BRIGHTEZT ZTAR!
I CAN TOUCH ALL THE ZTARZ!
I CAN EAT ALL THE ZTARZ!
I CAN KILL ALL THE ZTARZ!
THAT BLINDING LIGHT INZIDE....
KRIZ ARE YOU A ZTAR?
Secret boss 11...?? Correct me if I'm wrong
I loose count easily

Here's Aroce (pronounced like Aeros)
Theyre based on Aroace people (shout out to them) and how people just tend to shit on them so you know what? If people are gonna disrespect Aroace People we'll put them with the cool kids. The joker cards and spam emails
Aroce is one of the thrown out flowers and all the other flowers are talking about their boyfriends and girlfriends and Aroce feels like an outcast (mostly cause they make them feel like one)
Aroce begins to think that something is wrong with them because they can't feel the same love as everyone else and think that it's because they lack a lightner soul........oh shit not Kris!
They speak with gaps where letters should be but only when they think something is wrong with them. When they realize that they don't have to feel romantic love at the end of their fight by being shown friendship they talk normally.
Unfortunately though their realization is too late as in their fight they go super Sayans mega pissed and it drains their power tiring them out and they become a smol flower
Oh and when you first meet them only their tail is shown so it looks like Flowey
Oh and also their overalls and socks used the Aroace flag color scheme
We do not hate Aroace people here and everyone is accepted here.......
Except haters and people who put milk in before the cereal
All people are Non-binary
If you aren't made of 1s and 0s you aren't binary
Sorry to say my friend
This isn't Undertale related but I though this was funny
Pls tell me it is
Secret boss -2
Sorey guys but today and yesterday were chaotic and tiring so I don't have any secret bosses for ya
I'm super burnt out and hopefully tomorrow I'll be able to make some or flesh out the sketches I have
Also suggestions are greatly appreciated since I'm kinda running out of ideas and I feel the suggestions will also motivate me more
Thanks for the support
Quick Secret Boss
I'm still two behind expect them tomorrow
Here's a quick one

Get on your knees before the Queen Cara Carrie The Prom Queen
The Queen of Highschool Land
At least in her mind
In a Dark World taking place in the school Cara Carrie was the school popular bitch who had it all
She was a shoe in for prom queen
Then....Molly got her leg amputated and suddenly everyone was giving her pity votes
Her dad pressured her to be the Prom Queen
And so.....She did whatever it took
And when her boyfriend announced he was going to prom with Molly....Cara snapped
She killed all her F̶r̶i̶e̶n̶d̶s̶ Traitors and poured their blood on the P̶r̶o̶m̶ ̶Q̶u̶e̶e̶n̶ bitch Molly
She was arrested and all records of her cleared
Some people say she was put in the school basement in a straightjacket
But that's just a silly rumor right~
But now she's the prom queen and once she breaks free of her padded cell she'll make sure EVERYONE remembers CARA CARRIE
She obviously is a Muffet and Chara themed boss but is also based on the movie Carrie and also the main reason I made her is the song The Ballad of Sara Berry which is basically what I copied for her backstory
Still I think she turned out pretty fun and C̶r̶e̶e̶p̶y̶ Beautiful
Don't you think?~
Remember to Check Cara
Chose Cara
Vote for Cara Carrie
Secret Boss 13 I think
This is the most recent art I have but it's not in the usual format
This is part of a project where I make what I called "posters" for my secret bosses with specific songs in mind

This is Radiola with the song a Good Song Never Dies
Radiola is my chapter 3 secret boss prediction with a theme of radio being replaced by television. She also has a theme of beauty within which is why I made her conventionally unattractive. But the beauty within her is a bunch of robot spider legs. I have more info for her but I'm too tired to put it all here
So to make up for it here's some bonus drawings of the previous secret boss Cara Carrie!

This one is based on my favorite portion of The Ballad of Sara Berry:
P is for Patricia drinking Poisoned Punch! R is for Raquel dashed on a Rock...CRUNCH! "O" is what Anne said when Cara bludgeoned her brains! M is for Marianna's Marinated remains! But! But! Q is for Quiara Quiet drowned in the pool! U is for Eunice's pieces spread round the school! But Es are for the Easy way in 5 minutes tops...A one legged girl can bring an N for End by calling the cops...What a bitch! Now what's that spell? P R O M Q U E E N!
(remember to click it to see full image)

Here's an idea for an Omega Carrie and my generic description I sent to my friends
OMEGA CARRIE
I GOT THE SILVER KRIS! I GOT THE CROWN
I GOT THESE BLOODY ROSES AS HANDS
SPOILED SASH AND SCEPTER FOR ONE FINAL DANCE
KNEEL TO THE QUEEN OF HIGHSCHOOL LAND!
Cara has ascended to plantness. She's got a paper fortune teller holding her scepter and the heads of her victims watching from above. Six victims....Six souls....Now all she needs is one more

If you notice charecters I haven't posted here thats because they're really old and I lost the original art
If you want to know the reasonings of why they're dressed this way ask in the comments/reblogs (which are highly encouraged)
Lastly who's costume is best?
(The actual lastly....uhm do not use this as an accurate scaling for the characters because it is wildly off but most are accurate....the most inaccurate scales are Flowery, Ex Rai, Crysdoll, Creatos)
