Reference Sheets:
Chara is the 8th human to fall into the underground, and is also the protagonist and the playable character. They can speak, but they don’t usually like to. They fell into the underground for an unknown reason and now they must try and exit it.
Temmie is a goofy and crazed stuffed animal (stuffed monster?). They speak using random uppercase and lower case letters, they misspell words, and sometimes speaks gibberish, like how the temmies do in Undertale. They also run a shop of their own, selling various items. They can do crazy nonsensical things that usually involves their face.
Asgore is the former king of the underground and went back to the Sanctuary due to unknown reasons. In the Sanctuary, Asgore usually helps the locals and is supportive of mostly everyone there. He likes to walk around and water the flowers every once in a while. When not watering flowers or conversing with others, he boils some nice and hot tea and drinks it next to the warm fire. He also occasionally sends letters to other monsters on the other side of the Sanctuary door.
Mettacrit is the second mini-boss encountered in the Sanctuary. He appears egotistical and a outgoing during his shows, but is secretly caring and shy when alone. Both his bow and his crown are a gift from Asgore, once he moved back into the Sanctuary. His main goal is to entertain others, and make them smile.
Sans is a lazy skeleton who is the older brother to Papyrus, and occasionally makes bad skeleton puns. Like his brother, he does things that defy physics and make no realistic sense. He is a giant space nerd, and is great friends with Toriel and Alphys. He has a multitude of jobs, some of these are being a sentry in the Frozen Tundra and the Volcanic Ashlands, a comedian at Grillby’s, and a member of the Royal Guard. He enjoys playing the trombone and has trouble solving crossword puzzles.
Papyrus is a goofy and kind monster and is the younger brother of Sans. His only friend is Undyne, who he hangs out with most of the time. He likes to set up puzzles and create traps for potential humans, despite him falling in them most of the time. He dislikes Sans’s terrible puns, but he loves quality well-made ones. He also tends to break the laws of physics, like Sans. He looks up to Undyne as a role-model and he takes many ideas from her, and sometimes copies what she does. He seems egotistical, yet he just wants attention and someone to be friends with. He looks for the best in everyone, trying to help them with their struggles.
Alphys is the current captain of the Royal Guard, a special force which task is to escort humans to the Capital and fights rebels. She joined the guard because of her love for humans, and a need to protect. Outside of work, Alphys sits in her house eating tubs of ice cream watching Mew Mew Kissie Cutie. She’s depressed and insecure about herself, wanting others to like her. She loves Undyne, but is too anxious to admit it. Sans and Alphys are co-workers, who love to hang out and chill off-duty. Her scouter serves no function, she just thinks it looks cool.
Undyne is a fish monster who has a love for science, robotics, and explosions. Half of her face was burnt off in an accident , so she built herself a robotic covering. She’s the mentor and best friend of Papyrus, hoping one day, he can take her place as the Royal Scientist. Undyne is also in love with Alphys, being the one to initiate going out most of the time. When she was younger, she built a robotic body for one of her neighbors, wanting them to realize their dream. Now, they are an unstoppable duo, who do everything together.
Blastonkap is the Underground's second-most famous monster, the first being Queen Toriel. They're a magician, playing with cards, rabbits, and all of the sorts! They are actually a ghost monster, who got given a robot body by the Royal scientist herself. Together, they show and tour around the underground with explosions and magic!
Toriel. Toriel is the queen of the Underground, who took main control after the king mysteriously disappeared. She rules with a heavy burden, that being one of needing to kill seven human in order to free her kind. In order to help them get to her safely, she instilled a Royal Guard. One to guide humans towards her, and to protect her at any cost.
