Boss Fight Tracker

Endacopia has four fightable bosses plus one hidden meta-encounter. Three of the bosses (Trapezist, Chameleon, AI) are optional and have mutually exclusive fight / skip outcomes — you need at least two playthroughs to grab both trophies for each. Henry is the Ending A boss; Andyland is the developer cameo for The Yeti.

This tracker summarises each fight alongside the skip or alternate condition. Full mechanics live on the linked boss pages and in Optional Bosses.

Boss at a Glance

Boss	Location	Type	Fight trophy	Skip trophy	Skip route
Trapezist	Circus	Optional	Fatal Performance	Cut The Act	Scalpel → left rope
Chameleon	Office annex / Timesville	Optional	No Strings Attached	Case Closed	Grave name quiz
AI	Core	Optional	System Override	Short Circuit	Cooler mug → outlet (O / O / X)
Henry	Chapter II	Required (Ending A)	(none — required)	n/a	n/a
Andyland	Hidden room	Meta	The Yeti	n/a	n/a

Trapezist — Circus

Route	Trophy	Steps
Fight	Fatal Performance	Watch for the jump kick at half HP — dodge backward then punish twice. The boss arena opens after Whack-a-Mole.
Skip	Cut The Act	Use the Scalpel on the left rope while Trapezist is mid-monologue. Cut The Act triggers when he falls.

Patches: the room-exit exploit during the gunslinger fight was closed in 1.04; the fight itself is unchanged. Stay on 1.08+ for stable input handling. Full details: Trapezist.

Chameleon — Office Annex

Route	Trophy	Steps
Fight	No Strings Attached	The Chameleon changes colour between turns. The correct counter is colour-keyed: red → red, blue → blue, green → green. Use the watch-pendant animation as the timing cue.
Skip	Case Closed	Visit the Timesville graveyard and answer the grave name quiz. Five correct answers prevents the fight entirely.

Patches: a softlock during the fight was fixed in 1.03; chase music no longer sticks across day/night cycles after 1.04. Full details: Chameleon.

AI — Core Room

Route	Trophy	Steps
Fight	System Override	The Core room fight blocks your exit. The AI opens with a beam attack — dodge behind the fountain pen pillar. Phase 2 brings adds; use the Wrench as a melee finisher on adds only.
Skip	Short Circuit	Pour a cooler mug (green / green / red X) on the Core outlet behind the terminal. The breaker trips and the boss scene skips.

Patches: the Short Circuit combination was rolled back to the original dice code in 1.05 and finalised in 1.06. Camera freezes during the Core fight were addressed in 1.08. Full details: AI.

Henry — Chapter II

Route	Trophy	Steps
Fight	(required for Escape)	Henry is the Ending A final boss. Attack pattern is uvula-target — the uvula is his only weak point. Block two overhead swings, then dash in for one uvula hit. Repeat. The fight ends when the Saw Box is opened afterwards.
Skip	n/a	Cannot skip. Henry only appears on the Escape route. The Return ending skips the Henry fight entirely.

Patches: the Core button glitch when leaving the Core room was addressed in 1.08. Full details: Henry Boss.

Andyland — Hidden Encounter

Route	Trophy	Steps
Trigger	The Yeti	Find the Andyland developer cameo in a hidden room — usually reachable from the Misery Town cinema passage. After the dialogue, complete the dancing mini-game to unlock the trophy.

This is the rarest trophy at ~6.8% global. It can be triggered from any save file, including Runs 1–3 of an ending route. No patch-specific gating — works on 1.04+.

Fight vs Skip — Per-Trophy Unlock Rates

Numbers from Steam global stats on August 2026 snapshots:

Trophy	Global %	Note
Fatal Performance	68.9%	Trapezist fight
Cut The Act	20.6%	Trapezist skip
No Strings Attached	62.0%	Chameleon fight
Case Closed	31.0%	Chameleon skip
System Override	55.1%	AI fight
Short Circuit	10.3%	AI skip — rarest boss route
The Yeti	6.8%	Andyland dance

Short Circuit is the rarest boss-skip. The mug × outlet combination has a strict colour order (green / green / red X). Mistake the order and you trigger System Override instead.

Boss Route Cheat Sheet

For a single-route playthrough, the fastest boss path is fight Trapezist + skip Chameleon + skip AI — this clears the Chapter I boss block in one sitting with two trophies locked. For 100%, see Achievement Tracker and Ending Route Planner.
