Aaron is an enemy that can appear in Waterfall. He is a brown muscular merhorse (or rather a sea horse) with a long, winding green tail and a twelve-pack.
His lines are vaguely flirty as well as creepy, and he adds a winking face to the end of every line he speaks.
- Flexing muscular arms move upward from the right and left sides of the bullet board. They speed up as the seconds go by.
- Sweat falls straight & diagonally from the top of the box.
- 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, the protagonist, and Aaron will have increased attack.
- It takes only one flex to him to flex out after flexing at Temmie.
- If "Joke" is selected while fighting Aaron alongside Woshua, Aaron will become sparable.
- If the protagonist plays one of Napstablook's music CDs, Aaron and Woshua will be encountered in the room with the SAVE Point in front of Napstablook's house. They will be immediately scared off by how spooky the music is, unlocking the yellow text in the ending credits.
- After this event, his encounter dialogue is different, and it is possible to make Aaron leave in battle by shooing him.

- Napstablook's remix easter egg (With Aaron)
- If the protagonist turns on one of Napstablook's music and heads outside, they will encounter Woshua and Aaron, and trigger this easter egg. After it is complete, shooing Aaron will cause him to leave the battle.
- [Woshua] ... what the HECK is that music?
- [Aaron] I-I DUNNO, DUDE BUT IT'S SPOOKIN ME OUT ; )
- [Woshua] ... this is worse than Shyren.
- [Aaron] No way, Shyren is way less scary ; )
- [Woshua] ... if you're so scared, why do you keep winking?
- [Aaron] THESE ARE WINKS OF FEAR ; )
- [Woshua] Forget it. This beat is too... ... filthy.
- [Aaron onward] Wosh! Wait! Don't leave me ; )
- Is this creepy music my punishment for being creepy? ; )
- Please... stop... I'll never creep again ; )
- Wahhhhh!!!!! ; )

- You tell Aaron to go away. He agrees. [Shoo after having flexed or after scary music encounter.]

- Aaron is named after and slightly based on a former roommate of Toby Fox.
- When "Aaron" is typed for the protagonist's name, the response becomes "Is this name correct? ; )"
- A parallel seems to have been drawn between Aaron and an enemy from the 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 or spare sprite dies or becomes spared, it will display Aaron as he is the placeholder for any enemy without one.
- Aaron does not appear to tell the story of Asriel Dreemurr in New Home, possibly because he ends all his sentences in winks.
- Aaron is hated by all Temmies because of his constant flexing.
- Aaron has an apparent dislike for music. He may, however, just dislike Napstablook's tunes and Shyren's singing, specifically.
- Aaron is one of the monster species making up the Amalgamate Lemon Bread; specifically, Lemon Bread is spared by flexing, an ACT adopted specifically from Aaron, and Lemon Bread appears to have Aaron's bicep attached to its body and the ends of Aaron's tails for eyes. She also confirms this at the end of a True Pacifist Route, where she comments that her other parts do not look forward to seeing Aaron.
- Aaron is one of the few monsters who rewards more Gold if he is spared instead of killed.
