Undertale Multiverse Simulator How to Beat Pesti Sans

Pesti Sans is the event kit people search after they finish the starter room. Undertale Multiverse Simulator 1.5 splits him into two gates: defeat him for a badge, then pay 2,000,000 souls to use him. Winning the fight does not put the kit on your hotbar. Paying 2M without the badge does not skip the boss. You need both.

The Roblox badge is Pesti Sans Defeated. It is rare. The event is not a permanent lobby dummy — it has been re-added at least once, so if you log in and he is gone, wait for a rerun instead of assuming the page is wrong. Kit notes live on the event roster. Patch timing lives on the updates hub and 1.5 remaster notes.

Do you need 2,000,000 souls to beat him?

No. The 2,000,000 is the use cost after the badge. Community clears exist under 1,000,000 souls. Players who called the fight “easy” still warn that easy means long-range and slow, not a 20-second delete. If you stand in his face with a 4,000-soul starter, you will not get the badge.

If you have not opened the white portal yet, use the first-hour 1.5 join order first. Bring the best kit you can actually combo from the starter roster or the stronger character zone. You do not need a 2M kit to start the fight. You need range, a teleport, and a heal you understand. If your farm kit has none of those, keep following the soul grind pace and 200k breakpoint until it does.

Fight plan (community)

The strategy that keeps showing up in event comments:

1. Keep range. Close range is how he comboes you. Far range is how people with under 1M souls finish the HP bar.
2. Teleport away from the small blasters. If a small blaster spawns on you, TP first, dodge second. Do not trade HP to “finish a combo.”
3. Dodge the rest of the kit. He teleports, he spams, and he will sit on you if you panic-sprint in a straight line. Strafe, TP, then attack.
4. Insanity Blaster Chung + Axe Detonation. That is the damage pair players name for this event. Learn those two buttons. Mash-everything is how you die on cooldown.
5. Heal on cooldown, about 20,000 HP. The heal is not a full bar. Community notes put it around 20k with a long cooldown (players complain about two minutes). It will not outheal a full melee combo. It will cover chip if you stayed at range.
6. First heal around 230,000 HP. Do not wait until you are in the red. Pop the first heal near 230k HP so the cooldown is already ticking while you still have a buffer.

Community HP talk puts Pesti around 400,000 HP. That is a lot of chip from range. Budget minutes, not a highlight reel. If you only have short-range bones, you are on the wrong kit.

Controls that matter in this fight

• R / mobile low-HP still exists. If Pesti throws orange or blue bones, obey the color and use the low-HP bind the same way you would in PvP. See the PC, mobile, and gamepad bind sheet.
• Shiftlock (gamepad X) keeps teleports and blasters aimed at him instead of at the sky.
• Z emote wheel will get you killed. Close it.

This is still a 15-player server. Other players can body-block, steal the last hit, or dump you into a blaster. If the lobby is chaos, hop to a quieter event server. The badge cares that you defeat him, not that you did it in a stacked highlight clip.

After the badge

When the badge pops, you still need 2,000,000 souls to use Pesti. That is a late-game pad, not a starter reward. Do not freeze your farm to “save for Pesti” if you cannot yet buy a 200k zone kit — the soul grind pace is still the faster path to 2M. Check the use-cost on the pad with the soul unlock tool in case a rerun retitles him.

Pesti is a nuke in public PvP once equipped. He is not a shortcut to phases or evolution rooms. Buy those only if they raise farm speed on the way to 2M.

Event rerun notes

The event has come back at least once. Play when the title or lobby says he is up. If he is down:

• Keep grinding souls so the 2M use-cost is ready.
• Watch wiki Discord and community links for “event is on” pings.
• Recheck codes after a rerun in case the developer drops a string — we have not verified a public list, so do not invent one.
• Do not download a “Pesti auto-win” script. Scripts and auto-farm notes are high-risk. This page will not give you a loadstring.

If a patch removes blood or retunes maturity, the place can go temporarily unjoinable. That is a Roblox maturity issue, not a reason to join the hacked original. Souls still do not transfer from place 7915723993. Stay on 1.5 (place 112050560592995, creator SlayerRealNotFake).

Attempt card

Before you click the event:

• Kit with range + teleport + heal.
• First heal planned at ~230k HP (~20k restore on a long cooldown).
• Damage plan: Insanity Blaster Chung and Axe Detonation, not random melee.
• Small blasters: teleport off them.
• Badge first, 2,000,000 souls later.

Run that card, then go back to farming. The badge is the gate. The 2M is the shop. Everything else is patience at range.
