Aaron

Aaron is an enemy that can appear in Waterfall. He is a muscular, mer-horse (or rather a sea horse) with a long, winding tail and far too many abs.

His lines are generally vaguely flirty as well as creepy, and he adds a winking face to the end of every line he speaks.

Appears With

 * Temmie


 * Woshua


 * Shyren

Attacks

 * Flexing muscles move upward from the right and left sides of the bullet board. They speed up as the seconds go by.
 * Sweat falls down from the top of the box.

Strategy

 * To spare him, the protagonist must flex at Aaron, the first time he will take it as a challenge to a flexing contest, the second time he will flex harder, and the third time he will flex too hard and flex himself out of the room, meaning the protagonist has won by default.
 * After each flex Action is used the protagonist and Aaron will have increased attack.
 * If you select Joke while fighting Aaron alongside Woshua, Aaron will become sparable.
 * If you play Napstablook's music, Aaron and Woshua appear and are immediately scared off by how spooky the music is, which is the only way to get him to have the yellow text in the ending.
 * After this event, his encounter dialogue is different and it is possible to make Aaron leave in battle by shooing him.

True Pacifist Ending Credits
Once the player has gotten past Undyne into Hotland, Aaron, if alive, will be near the second umbrella bin near the view of the King's castle.
 * White Text - "Still Flexing"
 * Yellow Text - " Paranormal Investigator "
 * In order to achieve yellow text, the player must go to Napstablook's house in Waterfall, play one of the spooky songs, and then leave with the CD still playing. Walking around will trigger a unique encounter with Aaron and Woshua.

Lemon Bread comments that Aaron is now their brother.

When "Aaron" is typed for the protagonist's name, the response becomes "Is this name correct? ; )"

Trivia

 * A parallel seems to have been drawn between Aaron and an enemy from SNES game Breath of Fire II called Dir. HR which is also very muscular and shirtless. When it attacks it says "Education? Hobby? Talent!?" and then performs a flexing animation.
 * Additionally, Toby is aware of the Homestuck connection to this enemy.
 * When an enemy without a death sprite dies, it will display Aaron, as he is the place-holder for any enemy without one.
