In order to encounter Glyde, the protagonist must go to the Mysterious Door room outside Snowdin (with the four mushrooms), and move for about three minutes. This encounter must happen before the fight with Papyrus, or Glyde does not appear. The higher the kill count of the protagonist during the Genocide Route, the longer it takes for Glyde to appear- possibly upwards of thirty minutes.
Glyde is shown to be very pretentious and rude, doing anything to get the protagonist's attention and even getting jealous of itself at times.
- Waves of star-shaped bullets are sent towards the protagonist, similar to the final boss of the Neutral Route.
- Same as before, but larger, exploding versions of star-shaped bullets accompany it in-between waves, making it harder to dodge.
- Rarely, Glyde says one of its lines as if about to perform a normal attack, but then no projectiles appear.
- To beat them, the protagonist must applaud them twice and then do nothing for the rest of the battle.

- Glyde does fancy flips. [Neutral]
- Glyde sees its reflection and gets jealous. [Neutral]

- Glyde is dying, but in a cool way. [Low HP]
- Glyde's name was likely decided by the Kickstarter backer who had Glyde put into the game. Glyde's name may come from the word gleyde, which can mean "a disagreeable old man," referring to Glyde's unpleasant demeanor. Glyde is also an obsolete spelling of glide, referring to how Glyde has no legs and can be seen as floating or levitating.
- There is a small glitch that allows Glyde to be encountered a bit easier: If Undertale is open in "windowed mode" and lets the window lose focus, the protagonist continues to march on the spot, which allows players to do something else during that time. Walking and alt-tabbing while fullscreen has the same effect. One can also hold the " Up [↑], Down [↓]" keys, approach the north wall and march on the spot that way.
- Glyde may be a reference to the Mortasheen monster, Twileye, in both shape and personality. Mortasheen is a fictional world full of monsters created by Jonothan Wojcik.
