Endogeny

Endogeny (known in battle simply as "Amalgamate" before its spare conditions are met) is an Amalgamate found in the True Lab, where it is first disguised as floating debris in the fan room. It is the first Amalgamate to be introduced to the protagonist as one.
== Profile ==
Endogeny is composed of the Determination-filled SOULs of several dog monsters, including the parents of Dogamy and Dogaressa and other miscellaneous family members of Doggo, Greater Dog, and Lesser Dog.
=== Appearance ===
Endogeny takes the vague shape of a large canine, with two pointed ears atop its "head" where instead of a face it only has a single orifice. Its wide body has six digitigrade legs, which form the silhouettes of five smaller canines between them. The silhouettes between its legs gain satisfied catlike faces when it can be spared. Additionally, its wet facial hole stops dripping when contented into being spareable.
=== Personality ===
Endogeny displays the same excited behavior many of Undertale's dogs do, but seems to be unaware of the damaging nature of its enormous weight and powerful body, much like the Greater Dog. It exudes a fluid from its single orifice, which becomes a "happiness froth" when the Endogeny is excited.
== Main Story ==
=== True Pacifist Route ===
At the end of the True Pacifist Route, it can be seen with most of the other dog characters, revealed to be its family, outside the Snowdin Library. When interacted with it imitates the signature sound and (perhaps weakly) facial expression of Greater Dog, who probably inherited these traits from one of the members of Endogeny. Its yellow text in the ending credits lists it, along with the other Amalgamates, as living with its family, implying it continued to spend its time with the other dogs.
== In Battle ==
=== Attacks ===
* A sprite resembling the Annoying Dog (but with the Endogeny's orifice for a face) retracts its legs and reveals a rocket underneath its tail, using it to fly towards the SOUL in a straight line several times before the attack ends. This attack is capable of exiting the boundaries of the Bullet Board.
* The dog appears to the right of the screen, first faceless but then developing the orifice. Then it begins to move up and down while firing backward-facing arrows towards the SOUL in a random pattern.
=== Strategy ===
* Endogeny can be spared by beckoning, petting, playing and then petting again twice.
** Unlike the Greater Dog, ignoring Endogeny has no effect.
* The Hush Puppy can be used to pacify and spare the Endogeny immediately, as can the Stick (in a similar fashion to other dog monsters).
** After using the Stick or Hush Puppy, however, the regular set of ACTs still have to be carried out to achieve the yellow text in the credits for the Amalgamates, though using one of these items first makes this task easier, as it prevents Endogeny from attacking.

== Trivia ==
* The name Endogeny may come from the word endogenous, which means "having an internal cause or origin" and refers to the Amalgamate containing multiple members of a single family (and possibly hinting at it containing the parents of some of its own components). Like all other dog characters in its family, Endogeny contains the word dog within its name.
* In the Japanese localization, Endogeny is named "わんさいぼう", a play of word on "単細胞" (meaning "single cell") and "わん", the Japanese onomatopoeia for barking.
* Endogeny is the only Amalgamate that looks similar to its overworld sprite.
* Endogeny is the only Amalgamate that moves towards the protagonist on first encounter.
* Using the Hush Puppy during battle causes Endogeny to fade out prematurely before its contented version is shown.
* Endogeny's Check text is likely a reference to the "ABOUT THIS GAME" section on Undertale's Steam page, which states, "If you play this game, can you count the dogs for me? I'm not very good at it."
* The dog that Endogeny summons as an attack is called "nofacedog" in the game's files.
* The nature of one of its attacks combined with some of its flavor texts might suggest it possesses some form of propulsion on its body, such as a rocket.
* During the battle, Endogeny vibrates, gradually growing more intense as spare conditions come closer. Their orifice on their face also opens and closes faster.
* Music and sound related:
** The closer the protagonist gets to sparing Endogeny, the faster the battle music plays. It stops increasing in speed once Endogeny can be spared and is overlapped by a slowed-down version of Dogsong.
** Endogeny's theme before meeting spare conditions is titled "mus_woofenstein" in the game's files, this name is presumed to be a dog-related pun on Frankenstein and/or the game series Wolfenstein.
** Endogeny's theme seems to simply be the Experimental-Woofenstein preset from this Sytrus preset collection.
** The sound that plays in Endogeny's battle is entitled "mus_disturbing.ogg". It also plays in the Shower Creature's room. The sound effect audibly resembles or may be a distortion of washing windows that sounds like dog noises.
* In Deltarune, a gravestone implied to belong to that universe's version of them lists their name as "Muttler." It is unclear whether this is their name in the Undertale universe.
