All Slap Battles Bosses Ranked by How Few Players Beat Them
Bosses ranked by clears, not by vibes
Every boss in Slap Battles has a badge attached to beating it, and Roblox publishes how many players hold each badge. That turns “which boss is hardest” from an argument into a number.
Fewest clears first:
| Boss / encounter | Clear badge | Added | Players who cleared it |
|---|---|---|---|
| Pim | Banish the Night | 2026-08-06 | 38,697 |
| The Doctor’s patient | Glass Bones | 2025-12-03 | 288,235 |
| Rob / the sealing fight | Emissary Of Light | 2023-06-19 | 502,855 |
| The Garden | Garden of Erasure | 2024-10-11 | 549,517 |
| Dave (the tower) | Dodecacide | 2025-08-06 | 649,511 |
| The Kraken | Escape the Abyss | 2023-05-08 | 723,206 |
| Bob (Reaper + Nightmare) | See in the dark | 2023-07-11 | 826,564 |
| The eldritch past | THE ACCIDENT | 2022-09-15 | 981,291 |
| Pim in the maze | Da Maze Runner | 2023-05-23 | 1,111,805 |
| The Guide chase | It’s Finally Over… | 2024-02-23 | 1,408,787 |
| Bob | YOU MONSTER | 2022-07-29 | 4,876,434 |
What the ranking actually shows
Pim is not close. At 38,697 clears it is beaten roughly 126 times less often than Bob, and 7 times less often than the next-hardest encounter. Even allowing for it being the newest fight — three weeks old at the time of writing — the gap is too large to be recency alone. Its own companion badge proves the point: 117,412 players reached the heart of the abyss, and fewer than a third of them walked out with the clear. Full breakdown on the Pim boss page.
Bob is the tutorial boss of this list. With 4.9 million clears, killing Bob is something most committed players do. The harder Bob variant — doing it under the effects of Reaper and Nightmare, which the developer’s badge text sums up as “I CAN’T SEE A THING” — drops to 826,564.
Pim has been here before. Da Maze Runner (“unleash Pim in the maze… and live to tell the tale”) dates to May 2023 with 1.1 million holders. Pim is not a new character in 2026 — the August content promoted an existing maze threat into a full three-phase boss fight, and the clear rate fell through the floor.
Age is not difficulty
Read the table with one caveat: an older boss has had more years to accumulate clears. THE ACCIDENT from 2022 has had four years; Pim has had three weeks.
The correction is to compare fights from the same era. Dave (August 2025, 649,511) and the Doctor content (December 2025, 288,235) are both roughly a year old, and both sit an order of magnitude above Pim’s count. Pim is genuinely the wall.
Where these numbers come from
Every clear count, badge date and developer description here is pulled from the public Roblox badge API for universe 2380077519 on 31 August 2026. Boss identification maps each badge to its encounter using the developer’s own badge text. All 165 badges, sorted by rarity, are on the badge rarity index.
