Hellhole Bosses: the Five Named Bosses

HELLHOLE's official badges name five bosses — Gravemaw, Undergnaw, Rotmaul, Broodwidow, and Ashwing — and promise more. This page collects every documented fact about them, including the facts that are still missing.

Quick answer

What is actually documented

Official API (badge names and descriptions), checked 2026-11-10

Everything official about these bosses lives in their badges, and the badges say three things: the names (one defeat badge per boss), the scale (defeat counts in the tens of thousands), and the roadmap (“more to come soon”). First Blood — “You killed your first boss!” — has existed since June 28, 2026 and sits at 2.86M holders, so a first-boss encounter is a normal part of early runs rather than an endgame wall.

The win rates are the most informative number here: every named-boss badge lands between 0.114% and 0.167% on the Badges API's winRatePercentage, which means the five fights are tuned to a similar difficulty band once your loadout is ready. No single boss is the gate — the gate is preparation.

Preparation

The documented boss doctrine

Boss stats are unpublished, but the prep loop is documented by creator guides and it applies to every boss on the list.

Arrive with a full clip

All Things How's walkthrough frames bosses as floor-caps: start the fight with a full magazine, because a reload at the wrong beat is the most common first-encounter death.

Bank survival upgrades

Damage upgrades do not help if the boss two-shots you. The doctrine is to keep survivability stacking while you descend, so the fight starts from a stable baseline.

Learn the pattern first

Spend the opening seconds watching attack timings instead of dumping ammo. Every boss badge sits near a 0.2% API win rate — the fight is learnable, not a gear check.

Bring burst, not sprays

High per-shot damage (the Rifle's 42, the Double Barrel's point-blank burst) fits short boss windows better than sustained spray guns that force mid-fight reloads.

The roster

Reading the boss names

The names sketch the bestiary without any stats: Gravemaw and Rotmaul read as undead bruisers (the community wiki's zombie list places Gravemaw, The Undergnaw, and Rotmaul alongside the zombie roster), Broodwidow is insectoid, and Ashwing — the only winged name — suggests an aerial fight. The community wiki's enemy page also lists The Shrieker and a Creamer Boss entry, which shows boss-scale enemies may not all carry defeat badges yet. Treat the name readings as orientation, not mechanics.

Not documented

What this page will not invent

Boss health, attack patterns, spawn floors, and rewards are not published in any source checked. The community wiki's zombie list includes Gravemaw, The Undergnaw, and Rotmaul but leaves their HP and speed cells empty.
Which floor each boss spawns on — badges do not publish spawn depths.
Phase counts, attack lists, weaknesses, or reward drops.
Whether the “more to come soon” bosses have names yet — nothing official announces them.

The official Every Last One badge description ends with “more to come soon”, so the developer has confirmed the boss roster will grow.
