A hidden figure associated with rare events and corrupted text. The game implies a connection to a former Royal Scientist, but most details about W.D. Gaster are intentionally unclear.

W.D. Gaster

The prince of monsters and son of Asgore and Toriel. Asriel’s story is tied to the first fallen human and to Flowey; in the True Pacifist route, he becomes the final boss with overwhelming power.

Asriel Dreemurr

A sentient flower with no soul who manipulates events from the shadows

Flowey

A human child who falls into the Underground. Frisk’s actions—mercy, violence, and everything between—shape how monsters respond and which ending the world reaches.

Frisk

A laid-back skeleton known for bad jokes and sharp observations. Sans acts as a moral judge of the player’s actions—and becomes a deadly opponent on the Genocide route.

Sans

A ghost who inhabits a robot body built by Alphys. Mettaton is a glamorous star in Hotland, hosting shows and chasing fame—with multiple combat-capable forms.

Mettaton

An enthusiastic young monster from Waterfall who idolizes Undyne. Monster Kid is brave in spirit, often trying to do the right thing despite being outmatched.

Monster Kid

The first human to fall into the Underground. Chara was adopted by the Dreemurrs, and their legacy is closely tied to the game’s darkest route and narrator-like presence.

Chara

Napstablook

A quirky Temmie from Temmie Village in Waterfall. Temmies are known for their odd speech patterns, humor, and the Tem Shop.

Temmie

The Underground’s Royal Scientist. Alphys is brilliant but anxious, obsessed with anime and human culture, and burdened by the consequences of her Determination experiments.

Alphys

The kind but tragic king of the Underground. Asgore seeks to break the barrier trapping monsters by collecting human SOULs, but he deeply regrets the path that led to war.

Asgore

Sans’s enthusiastic younger brother. Papyrus is earnest, dramatic, and determined to join the Royal Guard by capturing a human—yet he’s also genuinely kind.

Papyrus

The former queen of the Underground who lives in the Ruins, protecting any fallen humans. Toriel is gentle but firm, and she refuses to accept more children dying for the barrier.

Toriel

The fierce captain of the Royal Guard. Undyne is bold and heroic, initially hunting the human for Asgore’s cause—yet she can become one of Frisk’s strongest allies.

Undyne
