Major Characters
FRISK
The fallen Human from the Surface. The seventh SOUL. To get home, they must embark on a perilous journey through the underground and confront King RUDOLPH. Say... could they always cast MAGIC?
FLOWEY
A blue Echo Flower from the Depths. It seems eerily kind, in its own stunted way... Could they be your new best friend?
DESS
The caretaker of the Depths, the deepest part of the Underground. The long-lost Daughter of King RUDOLPH, Dess opposes her father's quest to collect seven human SOULs. Though no human has ever fallen into the Underground from the Depths before... she will make sure you are safe here. How about a game of catch?
SAD DUMMY
They say there's a Dummy in the Depths that was brought there by Dess when she first moved there. She often uses it to practice ACTing, although rumor has it that the Dummy is haunted. That can't be true, right? .... Is it... crying?
NOTEBLOOK
A shy ghost that loves write. It seems to find the most inspiration within the Depths, but they say it lives on an orchard in the Golden Forest...
ALPHYS
A peculiar yet reserved monster living in Clearwater. No one knows very much about her, other than her love of anime... She just moved into Clearwater one day as Undyne's roommate. Is there more than meets the eye with her...?
UNDYNE
An aspiring member of the Royal Guard! She's tough as nails, and probably does more guarding than the rest of the Royal Guard combined! If that's the case, why hasn't Guard Captain Papyrus promoted her yet...?
ANNOYING TEM
A cat-dog-thing who seems to show up at the worst of times, much to Undyne's chagrin.
PAPYRUS
The Captain of the Royal Guard! More than just his strength, Papyrus is widely known for his kindness. No problem is too small for him to handle personally! Usually, he's patrolling the Golden Forest. Doesn't he get tired...?
GLAM DUMMY
There's a Dummy in the landfill that constantly seems to be wearing new clothes! Has someone been dressing it up?! Why is it... blushing???
GLAM GLITTER-KUN
The Ghost that lived within the Glam Dummy has a new body! Somehow, he has gotten his hands on a Limited-edition Glitter-Kun doll! Although... it seems he's still struggling to fully fuse with it.
TOBY
A species of dog monsters that has made a thriving community in the basement of Papyrus' house. One of them has even set up a shop there, and that hat that he's wearing's like his personal crown.
SANS
The Royal Scientist of the Underground who operates out of his lab in Highpeaks. Although, very few have actually seen him do any work... He's usually just watching sitcoms...
MADDATON
The Underground's most famous robotic punk icon! She's widely-known for her songs criticizing King RUDOLPH... There's nowhere you can go in Highpeaks without seeing her merchandise plastered somewhere! They say that she was created by the Royal Scientist as a weapon but quickly rebelled against her masters... Is that true?
KING RUDOLPH HOLIDAY
The King of the Underground, ruling from his Ice Palace on the highest peak. Cold and distant, few have actually seen him in person. They say his SOUL froze over after the tragedy involving his children, yet his palace is still decorated in Christmas lights...
CHARA HOLIDAY
The first fallen Human, and third child of King RUDOLPH. They say they were a fallen star, gifted from the Titans as a blessing. When they died, the entire Underground's hopes and dreams were crushed.
