Frisk

Frisk is the playable character and main protagonist of Undertale. After Frisk falls into the Underground, they embark on a journey to return to the surface, whether peacefully, neutrally or genocidally. Frisk's name is only revealed in the True Pacifist Route, confirming that they're not the "fallen human" whom the player names at the beginning of the game.

But this au that we rp in, she has a friend named Katie

### Personality

Underfell FriskUnderswap FriskFrisk'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, indicating bits of their personality (although that could be questioned depending on the route).

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, or when Papyrus presents his house at the start of their date running a full circle.

### 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. 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.

### Main Story

#### Undertale

Flowey attempts to kill Frisk after he pretends to offer honest advice. Toriel intervenes, hits Flowey with fire magic, and serves as a guide to the Ruins. At the end of a long room, Toriel asks Frisk to wait for her to return and states that she has errands to do. To be safe, Toriel gives Frisk a cell phone to call her with.

Frisk travels through the remaining puzzles in the Ruins and eventually arrives at Toriel's home. They ask Toriel "how to exit the RUINS," which prompts Toriel to destroy the Ruins's exit. Toriel then battles Frisk because she wants them to prove that they can survive outside of the Ruins.

Then, Frisk meets Sans and Papyrus in Snowdin Forest. The brothers set up traps and puzzles in an attempt to capture Frisk. After passing through Snowdin, Papyrus battles Frisk.

Undyne, the head of the Royal Guard, pursues Frisk throughout Waterfall. Monster Kid often saves Frisk from Undyne by accident because they are so excited to see Undyne in action. After a chase scene, Undyne destroys a bridge that Frisk is standing on, and Frisk falls into the Garbage Dump. Before they get up, they recall a memory from the first human. In the garbage dump, Mad Dummy battles Frisk after accusing them of mistreating their cousin, Dummy, in the Ruins. At the end of Waterfall, Undyne battles Frisk after she gives an abridged monologue atop a crag.

After entering Hotland, Frisk enters a lab and meets Alphys and Mettaton. Alphys tells Frisk that she is not a bad guy, and Mettaton interrupts them with a quiz show. Alphys gives Frisk an upgraded cell phone after the quiz show concludes. She guides Frisk through Hotland and the CORE, helping them solve puzzles and evade Mettaton. Before his battle at the end of the CORE, Mettaton reveals that Alphys had created all of the traps in Hotland in an attempt to endear herself to Frisk. He then transforms into Mettaton EX and battles Frisk.

While passing through New Home, the capital of the Underground, Frisk learns the story of Asgore and Toriel's children from passing monsters. Then, Sans judges Frisk in the Last Corridor and explains the meaning of LOVE and EXP. He also emphasizes Frisk's importance in the fate of the world.

Frisk enters the Throne Room and finds Asgore, who tries to make small talk, only to realize their fated confrontation. The two walk to the Barrier and Asgore gives Frisk one last opportunity to leave before fighting.

Just before the fight, Asgore shows the six collected human SOULs, preparing the containment process after the battle. Right before the fight starts, Asgore destroys the MERCY button with his trident, making it impossible to spare or flee. However, at the fight's conclusion, Frisk can explicitly choose whether to spare or kill Asgore. Regardless of the choice made, Flowey appears, destroys Asgore's SOUL and takes the human SOULs. The game then abruptly closes, or restarts from the fake "humans and monsters" intro on the console versions.

After reopening the game, Frisk finds that Flowey has saved his own game over the SAVE file, having gained the power to do so with the stolen human SOULs. Loading Flowey's game, Frisk confronts a powered up Flowey and defiantly steps forward, entering an initially hopeless battle with him.

After Frisk calls for help several times, the stolen SOULs begin to revolt: first, they heal Frisk, and then they weaken Flowey, leaving him vulnerable to destruction. After Frisk reduces Flowey's HP to 0 and listens to his monologue, the SOULs remove his ability to SAVE or LOAD, and then finish him off. After this, there is an option to kill or spare a weakened Flowey before leaving the Underground, returning to the surface, and ending their journey.
