Genocide Frisk

Appearance Frisk is a yellow-skinned human child who wears a long-sleeve blue shirt with two purple stripes, blue pants (often depicted as shorts in the official Undertale merch), and brown shoes (usually depicted as black or in a darker tone). They have medium-length straight brown hair, short and choppy bangs, and a blank expression. Though Frisk does not show much expression in the overworld, NPCs often describe Frisk's expressions. Just like the first human, they have no stated gender and are solely referred to with "they/them" pronouns throughout the game, or by generic terms (such as "child", "human", or "kid".)

Personality Frisk's personality is usually ambiguous, allowing the player to project any personality onto Frisk since they're very often speechless to them. However, the narration that describes Frisk's actions occasionally changes depending on their LOVE. Frisk speaks to NPCs throughout the game, especially when ACTing in encounters, but the exact dialogue is shown only when the game gives multiple dialogue options. NPCs' dialogue boxes display "..." to show that the NPC is listening to Frisk, and some NPCs respond to questions that Frisk asks.

Depending on their actions, players can interpret Frisk as merciful and kind, or merciless and violent. Some NPCs emphasize Frisk's kindness, understanding, and grace in the epilogue. Frisk is obedient and only disallows player input when they follow someone else's instructions, such as when Sans tells them to hide behind the conveniently-shaped lamp.

Abilities Frisk's determination grants the power to SAVE, heal at SAVE Points, and respawn at SAVE Points after death. This power emerged when Frisk first awoke in the Ruins. Frisk can reload the SAVE file to repeat events that occur after it, but NPCs' memories are not completely erased unless a True Reset occurs or after completing the Genocide Route. After the True Pacifist ending, Flowey's dialogue implies that Frisk is not the being who is manipulating SAVE files.

Frisk is the only character who is ever shown using items or gaining EXP.
