Undertale Multiverse Simulator Scarlet Tenacity

Scarlet Tenacity is a new 1.5 kit, not a leftover original-wiki starter. SANES 2’s 5 August 2026 video is the public clip this wiki trusts for the name: it shows a Scarlet Tenacity base, a Phase 2 evolution, and a Phase 3 evolution. That is a three-row line. It is not a free white-portal pad, and it is not a hidden keybind.

This page is the kit page. The evo map for the rest of 1.5 lives on character evolutions. Click order lives on how to evolve. If you still need a farm kit, stay on the starter roster until you can read Scarlet’s stand without guessing.

This wiki does not embed that August showcase here. The same upload is already the video on how to grind souls. One page, one video. Use the grind page if you want the footage; use this page for the shopping facts.

What the August 2026 video actually added

The same SANES 2 clip that introduced Scarlet also flagged other 1.5-era adds in the same pass:

• Scarlet Tenacity — base + Phase 2 evo + Phase 3 evo (this page)
• Swapfell Papyrus Phase 2 — evolution on the Swapfell Papyrus line
• Hyper Dust Sans — Ruins Dust evolution (not Hyper Revert Dust, not HyperDust Ink)
• Fatal Error Sans — evolution kit, not the left-room Error pad

Those four names get mashed together in comments because they dropped in one video. They are four different pads. Swapfell P2 still wants the base Swapfell Papyrus from the cheap Papyrus lane. Hyper Dust still wants Ruins Dust from the white portal. Fatal Error is a late evo with a large (and often misquoted) soul number — believe the 1.5 door, not a 2025 description. Full notes for those three sit on character evolutions, not here.

Soul cost: unknown on purpose

Public soul costs for Scarlet were not listed in that showcase. This wiki will not invent 1,000,000 or 2,000,000 to fill a table. Read the in-game pad. If the stand is missing, you are in the wrong room. If a Discord screenshot shows a number, treat it as rumor until you can reproduce it on place 112050560592995.

Log a figure in the soul unlock tool only after you see the live price yourself. Until then, Scarlet is optional. It is not a substitute for Photonegative at 200,000, and it is not a reason to skip the soul grinding route.

A few planning rules that do not require a leaked number:

• Plan for a late-game dump, not a day-one buy.
• Each row is a separate purchase. Phase 3 is not a key press after Phase 1.
• Servers hold 15 players. A kit you cannot drive in that lobby is a trophy, even if the model looks new.
• Souls do not transfer from the hacked original place 7915723993. You are buying Scarlet on a fresh 1.5 count.

Phase 2 and Phase 3 are evolutions

Scarlet’s ladder is the same idea as other 1.5 evos: extra soul prices on a kit you already own. The community showcase labels Phase 2 and Phase 3 as evolutions. Walk to the dedicated pads, pay the listed souls, and the kit changes. That is the whole mechanic.

R is not a phase key. R lowers HP on PC. Z opens the emote wheel. If someone told you to “press R to go Scarlet Phase 2,” they mixed up the low-HP bind with shopping. Read how to evolve for the click order and how to phase if you still think a transformation input exists.

1.5 still has leftover pads from the original layout. Community reports include clicking one evo door and loading a different AU room. If Scarlet’s room title, music, or pads do not match the door you clicked:

1. Do not buy.
2. Leave the room.
3. Re-enter from the lobby, not from a nested door.
4. Hop servers if the instance is stuck.
5. Only then spend souls.

Keep a cheap starter equipped so you can fight your way out if a pad strands you. That fallback is why the starter roster still matters after you start chasing August names.

Where Scarlet sits versus starters and events

Scarlet showcases often sit next to leftover starter-side footage, which is how players assume it is a white-portal kit. It is not Pacifist. Pacifist Sans is the free 0-soul floor. Scarlet is a later line with an unlisted public cost.

It is also not an event kit in the Pesti sense. Pesti Sans is 2,000,000 plus the Beat Pesti badge. Obsessed Monster is 2,900,000. Those live on event characters. Scarlet does not pick up a public badge gate in the August clip we trust. If a later patch adds one, believe the stand and check the updates hub.

A sane buy order that does not require guessing Scarlet’s price:

1. Own a farm kit from the starter roster. Pacifist is enough.
2. Follow how to grind souls to the 200,000 stronger-zone door.
3. Pick one mid line you will actually play (Photonegative, Epic, Toxin) using the soul unlock tool.
4. Touch Scarlet when the stand is visible and you can read the number. Until then it is a showcase name.

Do not pause the entire account on Scarlet while you still cannot live in the 200k rooms. August 2026 footage is a shopping alert, not a day-one route.

What this page will not do

It will not reprint original-game Fatal Error prices as Scarlet costs. It will not copy a comment that says “Scarlet is 2 million.” It will not treat Phase 3 as a secret input. It will not list Scarlet as a badge boss next to Pesti.

It will also not claim a NULL zone at 10,666,666 exists in 1.5. That listing is original-game wiki material.

Promo codes, if they ever appear, do not unlock Scarlet. Redeem from the codes hub only after this wiki verifies a string. Patch order for new evos lives on the updates hub and version 1.5. Discord pointers sit on Discord links.

Scarlet Tenacity is a three-row August 2026 line with a pad you have to read yourself. Until that number is public, it is a showcase name, not a budget line on the soul checklist. Walk in with the right door, the right soul count, and a farm kit you can still use if the buy is a mistake.
