Endacopia Bosses: All 15 Fights, Skips and Achievements
Updated 2026-09-08 · Last verified 2026-09-08 · Steam Endacopia
Endacopia has fifteen documented boss encounters: seven main-line and eight side or hidden ones. That two-way split is not our invention. It is the classification used by the official Fandom wiki's own Bosses page, and we have kept it intact so that this page can be checked against the source rather than compared with it.
Spoiler notice. This page names every boss, the region each one occupies, and the fate of several of them. It also reveals what the world of Endacopia is. Read no further if you want the game to surprise you.
Content warning. Steam's own descriptor for Endacopia reads: "This game contains scenes of body horror, psychological horror, distressing imagery, blood, violence, death, drugs, and jump-scares." Several entries below, in particular God and the interior of the clown head, sit squarely inside that description.
How combat works, and why it barely matters
Combat in Endacopia is first person and bare-fisted. Steam's official description lists it as "Use Mellow's bare fists to block, dodge, and punch monsters in first person perspective", and the Fandom wiki's Achievements page describes it as traditional HEALTH and STAMINA combat. Those two accounts agree, so the three verbs and the two bars are safe facts.
The Fandom Bosses page then makes a claim that is worth quoting because it reframes the whole lineup: "combat is not a focus of Endacopia whatsoever, as someone in a first playthrough could reasonably skip nearly every single boss (including main bosses, minus Clockey) without any combat." That is a single source, but the Steam achievement statistics back it up independently, which is unusual enough to be worth trusting.
Outside the combat verbs, nothing about the fights is documented in numbers. There is no frame data, no timing window in seconds, no damage figure and no health value for any boss in Endacopia, from any source we accept. That includes Henry, where a competing site publishes a precise sub-second counter-window that appears nowhere else and rests on nothing. If a page gives you exact frames for an Endacopia fight, it made them up.
The three regions are three lost senses
The structural idea behind the boss lineup is the sense system. Steam's official plot line describes Mellow as "a young boy named Mellow who has lost all his senses in an attempt to escape an uncomfortable home." The three main regions each return one of them, and each region terminates in one of the three skippable main bosses.
| Region | Sense recovered | Region boss | Fight achievement | Skip achievement |
|---|---|---|---|---|
| Misery Town | Mellow's hands | Trapezist | Fatal Performance | Cut The Act |
| Timesville | Mellow's eyes | The Chameleon | No Strings Attached | Case Closed |
| The Office | Mellow's mouth | The AI | System Override | Short Circuit |
The three regions can be tackled in any order. That is confirmed twice over: Steam's own feature list says "Decide which area to explore next in whichever order you'd like", and the Fandom Chapter I page states that any of the three main bosses can be fought. The hub connecting them is called "the green place", which is the name the Fandom infoboxes use in two separate location entries. It is not called "Green Hills"; that name appears on one competing wiki and nowhere in the source material.
Main-line bosses
Seven entries, exactly as the Fandom Bosses page groups them. Four of the seven, Clockey, Henry, RODGER and Toilet Parasite, carry no achievement of their own — only the Trapezist, the Chameleon and the AI have a dedicated fight/skip achievement pair.
| Boss | Where | Achievements | What is documented |
|---|---|---|---|
| Clockey | Mellow's Room, in the prologue | None | The one boss the Fandom wiki exempts from its "skip everything" claim. Built by the Surgeon. Re-encountered in the same room during the Ending C route as "Ticked Off Clockey", where the wiki's own infobox lists Mellow's Room in Chapter 3 as its place of death. |
| Trapezist | Misery Town | Fatal Performance (fight), Cut The Act (skip) | The circus region's closing fight. The skip is performed with the scalpel, obtained from the whack-a-clown minigame, used to cut the rope. |
| The Chameleon | Timesville | No Strings Attached (fight), Case Closed (skip) | Canonically named Ozzie. The fight achievement is earned by defeating him without saying his name. The skip requires calling him by his real name, telling him the film had impact, and saying that it is ironic. The Fandom page on him is one of the site's largest, at over 9,000 bytes. |
| The AI | The Office | System Override (fight), Short Circuit (skip) | The skip uses the transparent mug filled with water, poured onto the socket. This deliberately crashes the game to desktop; reopening it puts you past the encounter. The Fandom page for the AI is a stub, so beyond this the record is thin. |
| Henry | The final encounter on the Ending A route, inside God's mouth | None of its own | The documented approach is to bait Henry's bat into striking God's uvula. That is the whole of what is recorded. Frame data and timing windows for this fight are not documented anywhere; do not trust a page that supplies them. |
| RODGER | Chapter II, behind the mirror | None | Fully skippable. Entering the mirror and simply continuing to run drops you through a trapdoor and lands you at Henry. RODGER is a failed copy built by the Surgeon; "Fake Mellow", "Mirror Mellow" and "Mimic" are all unofficial names the wiki explicitly rejects. |
| Toilet Parasite | Recurring throughout | None | Listed as a boss by the wiki but functionally a fixture of the route: it is the creature you hand the saw to at the end of Chapter II, and the recipient of the password on the Ending C route. One competing site says the saw goes to Roger. It does not; three sources say the toilet. |
The three fight-or-skip pairs are the most useful thing on this page for achievement hunters, and they are covered in full on the achievements page alongside the other ten. What the global unlock rates show is that most players fight. As of 8 September 2026, per Steam's global statistics, the fight achievements sit at 57.1%, 50.5% and 49.1%, while the corresponding skips sit at 23.5%, 23.8% and 19.4%. Roughly twice as many players punched their way through each region boss as talked or improvised their way around it, despite the wiki's insistence that combat is optional. Unlock rates are live data and will drift; the date is the point.
Side and hidden bosses
Eight entries, again following the Fandom wiki's own grouping. Every one of them is missable, because every one of them requires a specific object or a specific interaction to open. This section rests largely on a single source, the Fandom Bosses page, which describes each trigger in unusual detail but is not corroborated elsewhere. Treat it as well described rather than cross-checked.
| Boss | Where | Trigger and what is documented |
|---|---|---|
| Yew | Chapter II, the house | Insert Henry's floppy disk, log in as Henry, open the file named "aaaa", then click the crossed-swords icon. Cannot be fought in Chapter III. |
| The Mug | Timesville, the apartments | Available after Paisley's Yellow Party. Pry open the rear right room, then interact using the transparent mug and the green mug. |
| Chimeramanticore | Misery Town, triggered from Timesville | A two-region chain: use the telescope on the Timesville beach during the first night phase to connect the constellation, dig up the Broken Phone with the metal detector, then use it on the white bird atop the lamppost beside the Pierrot's stall. |
| Benjamin | Misery Town, the level above the Pierrot's stall, right side | Must be engaged with the touch action. Using the talk action instead results in an instant kill. Right click cycles the view, touch and talk modes, which is why this one catches people out. |
| Underground Fighters | The Office, beneath the Gambling Den | A four-opponent gauntlet. Unlock both job positions, spin "ERROR" on the wheel, take the new elevator floor that appears, and pick the door with the lockpick found in Timesville. Each win pays 2,000 credits. |
| MatchBOXER | First of the Underground Fighters | Throws 24 attacks in total. The box front reads "25 Inside!", which is the joke: one match is unaccounted for. |
| Clown Crawler | Inside the clown head, Misery Town | The wiki previously filed this one as "The Magician" and has since retired that name. |
| God | Everywhere, in the most literal sense | Strictly not a boss. It is the colossal entity inside whose body the entire game takes place. Its uvula is the target during the Henry fight, and in Endings A and B it dies in 2002, in "The Desert". |
Two honest gaps in that table. Only two of the four Underground Fighters have documented names, MatchBOXER and a second fighter recorded as Tuna. The remaining two are unnamed in every source we accept, and we are not going to pad the list to four. Separately, the Fandom page for the AI and the pages for Timesville and The Office are all marked as stubs, so several of the triggers above are better documented than the regions they sit in.
What is not documented
The honest limits of this page, stated plainly, because the alternative is what the competing sites do.
- No frame data, no timing windows, no damage numbers, no health pools. Not for Henry, not for the Trapezist, not for anyone. The combat verbs and the two resource bars are the entire documented system.
- No boss order requirements beyond the confirmed fact that the three regions are open in any order.
- No documented Chapter III boss layout. The Fandom wiki's Chapter III page is three bytes long and reads "tba". What is confirmed about Chapter III comes only from the endings page: Henry is fought on the Ending A route, and Yew cannot be fought there. Beyond that the record stops, and anyone filling the gap is filling it from imagination.
- No names for two of the four Underground Fighters.
- No confirmed boss connection to the endings. Endings A and B split on the toy saw versus the real saw in Chapter II, and Ending C turns on hidden content in the three regions plus the password
cheshire. No boss outcome is a documented ending condition.

Update log
- 8 September 2026: Page created. Boss split of seven main-line and eight side or hidden taken directly from the official Fandom wiki's Bosses page. Six fight-and-skip achievements and their global unlock rates pulled from Steam's global statistics on the same date; rates are live data and will drift. Combat verbs cross-checked against Steam's official store description and the Fandom Achievements page. Frame data, timing windows and damage values deliberately omitted because no source documents them.
Frequently asked questions
How many bosses does Endacopia have?
The official Fandom wiki's Bosses page splits them into seven main-line bosses and eight side or hidden ones, which is the split used on this page. That gives fifteen documented encounters, though one of the eight, God, is not really a fight at all and one entry, the Underground Fighters, is a group of four opponents of whom only two have documented names.
Can you skip bosses in Endacopia?
Yes. Three of the main-line bosses, the Trapezist, the Chameleon and the AI, each have a documented non-combat route, and each route has its own Steam achievement. The Fandom wiki goes further and states that a first playthrough could reasonably skip nearly every single boss except Clockey without any combat. RODGER can also be run past.
Which Endacopia bosses are missable?
All eight side and hidden bosses are missable, because each one needs a specific object or a specific action to open the fight. Yew needs Henry's floppy disk, the Mug needs the transparent mug in a pried-open apartment room, the Chimeramanticore needs a constellation puzzle and a metal detector, and the Underground Fighters need both Office jobs plus a lockpick from Timesville.
Is there frame data or a timing window for the Henry fight?
No. No source we accept documents frame data, timing windows or damage numbers for any Endacopia fight, Henry included. What is documented is the approach: lure Henry's bat into striking God's uvula. Sites that publish exact dodge windows in seconds are inventing them, and one of them invents whole rooms and safe codes as well.
Do I have to fight Clockey in the prologue?
The official Fandom wiki states plainly that it does not matter whether you fight Clockey or not. At least one guide site claims you must avoid the fight to keep Ending C available. Those two claims are in direct conflict and there is no reliable consensus, so treat the requirement as unproven rather than real.
Does beating bosses matter for the endings?
Not directly. Ending A and Ending B split on which saw you take in Chapter II, not on any boss result, and Ending C turns on hidden content in the three regions plus the password cheshire. Bosses matter for achievements and for progress through each region, and Henry is the final encounter on the Ending A route.
