PGB Deltatale is Paul Grote Beverborg's take on the AU Deltatale, combining Undertale and Deltarune (currently) chapter 1. As new chapters get made, multiple things may change in the future. In this take, darkeners are new species of monsters.

Disclaimer: as everyone has their own ideas for this, none of this is canon, and everyone can make their own takes on it if they want to.

Kris is the 8th human to fall down in the Underground.


Spadey the Spade is a spade-shaped flower who first appears in the Castle Ruins. He's very similair to Flowey personality-wise, though he has some Lancer quirks, like calling Kris a clown instead of an idiot, and having as motto "It's thrash or be thrashed!". Themes: Your Best Card, Your Best Bad Guy, Ace of Finales


Ralsei is the prince of the Castle Ruins, but after Chaos King imprisoned the kings of Fielddin, Leaffall and Basementland, almost all of his subjects were taken to these areas. The only reason he wasn't imprisoned was the fact he's a child, and wasn't considered a threat. The emptiness of the area made him lonely, but he's still optimistic somebody will overtrow the king and reunite him with his subjects. Theme: Heartdusk


Unlike in Undertale, the Dummy is't posessed by a ghost. It's just a dummy... It also looks like Ralsei.


Berdly is one of Alphys students, and went to the Castle Ruins and later Leaffall for his project about monsterkind's history. He acts like he's very smart, and is pretty much a jerk to Kris. If his HP is lowered enough in his battle, he runs away, as he can still be hit as he isn't a ghost. Theme: Bird Fight


Alphys is a teacher in Fielddin, and is supposed to guard the entrance. However, she ignores this order, as she isn't a fighter, and she likes humans. She helps Kris troughout their journey, and isn't afected if Rouxls Kaard is killed. She loves making anime references. Themes: Alphys, Song That Plays When You Need To Learn Something, They're Teaching Somewhere Else, School's Over

Undertale text box

Rouxls Kaard

Rouxls Kaard is a very enthousiastic puzzle maker, but he is terrible at it, and thus never got allowed to join the Royal Guard. One thing he is good at however, is making mac and cheese, and when he does, nobody can stop him. He tried to get Alphys so far to teach Fielddin's inhabitants his way of speaking, but with no success, so he decided to become a teacher himself. Themes: Geeh hee hee hee! + Kaardtrousleth, Puzzling Starteth, Puzzling Tense, Puzzling Fighth

Top Chef

Top Chef owns a cake shop in Fielddin, often visited by Alphys.


Toriel and Asgore run a flower shop in Fielddin together, though on Toriel's demand, they're also selling other things.


Noelle has a secret crush on Susie, but due to her being too timid to say it, she just follows after her when she's on duty.


Susie is the captain of the Royal Guard, wich in this world not only is tasked with obtaining human souls, but also creating fear among the inhabitants, wich is one of her favorite things to do, wich is why she was made captain. She likes beating disobedient people up and make them work for her afterwards. However, deep inside she feels bad for what happened to Lancer, the only friend she ever had. Themes: Susie, Die!, OUTTA MY WAY!, Axe of Anger, But The Bad Guy Became The Hero, Battle Against A True Bully

Seam is the Royal Magician, sometimes working together with Malius to create stuff, trying to find a way to break the Barrier by magic instead of scientific means. Offered Lancer to store his broken Trash Machines in his basement. Theme: Seam


Jevil used to be a ghost, and Seam's friend, but due to his chaoticness, the King ordered Seam to seal him away in a prison. However, he sealed him away in a body made by Malius, hoping to be able to control him. This failed, and he took complete control over Basementland and the CORE.

However, when his son got killed, he took control over all of it, and ruled it like a tyrant. He has a hatred for humans, and won't rest until all of them are destroyed. Themes: Konig der Spaten + CHAOS KING

Thrash Machines

Seam offered Lancer to put his broken designs in his basement, however, this was a bad idea. A magic accident made them come to life, turning them into mindless grey creatures destroying everything that moves they encounter.

- Memoryhead is a custom Thrash Machine, made of Lancer's spare bike as wheels, a laser trap as body, and a spade as head.

- Endogeny is the combination with the highest level of the Guns category.

- Snowdrake's mother is the duck.

Themes: We Shall Thrash, Thrashmalgam, Thrashenstein, So Painful


Lancer was the son of Chaos King, and his heir to the throne, but he got killed by the first human, who tried to go trough the Barrier using his soul, and later got turned into a flower by Seam's magic. Before his death, he was a bit of a jerk, building Trash Machines to trash everyone who disobeyed his father. Themes: Thrash Memory, Spades and Lancers, Get Thrashed in Despair, Thrash the World, Lancer's Theme

Top Chef's

Top Chef's is a cake shop, one of the most famous shops in the Underground. Many people visit to taste these delicious desserts.


Leaffall is a maze-like forest filled with bright red trees. A majority of the area is broken down, as Susie tests her weapons on the trees and structures a lot. Theme: Leaffall

Susie's house

Susie's house doesn't differ too much from Undyne's, though it's less fish-like in appearance.

Checker Village

Basementland is a dark area, wich contains most of the Underground's prrisons. It once lied below Card Castle, until and earthquake moved the castle away from it. After Jevil took over, it became very chaotic, and Jevil's shows are much more deadly than Mettaton's, some completely relying on chance if it wasn't for Seam's help. Theme: Another Numbers Game

Seam's Lab

The lab isn't truly a lab, only known as one in the official documents. The entries in the basement contain information about Jevil, instead of the Thrash Machines. Themes: Seam, We Shall Thrash

Clover's House

Clover has her house near Jevil Resort, where she holds her birthday party. It has the same color scheme as Card Castle. Theme: April 2012

The CORE used to be powed by K Rounds dancing, but when Jevil took over he upgraded it to use the revolving of the world itself... somehow. Theme: The CORE Revolving

Card Castle

Card Castle is slightly bigger than New Home, and also filled with a few puzzles. The Judgement happens on the castle roof, with the Throne Room behind it, opposite to how it is in Deltarune.


  • When new chapters arrive, some story points may heavily change, like multiple characters taking a role, or new roles getting added.
  • The Boss monster souls still persist after death, and together with the spades and with PGB Deltatale Ralsei being one too, that makes 5 characters having that ability in this AU.
