Glyde
OK! I rule! I admit it!
Glyde, being applauded
Glyde (JP: グライド) is an optional miniboss that can only be encountered outside of the mysterious door in Snowdin.
To encounter Glyde, the protagonist must enter the mysterious door's cave and move for at least two minutes. This encounter must happen before the fight with Papyrus, and any fleeable Snowdin enemies must not have been killed. Otherwise, Glyde does not appear. Alternatively, if at least one monster was killed, the encounter must happen before the date with Papyrus and before Snowdin's kill counter is exhausted at 16 kills.
Glyde is a monster resembling a whale (or a flying fish). It has no legs, and it floats slightly above the ground. The fins on its sides form a crescent shape, and its tail ends in a circular opening, from which it summons its magical attacks. Glyde constantly has a huge, toothy grin on its face.
While it is never seen on the overworld in Undertale, it was found there in the 10th Anniversary Stream; according to its sprite, it has a black body, rainbow stripes on its wings, and a yellow tail.
Glyde is excessively pretentious and rude, which is present through its actions and words. Glyde does anything to get the protagonist's attention, and even gets jealous of itself at times.
The name Glyde is an obsolete spelling of glide, referring to how Glyde has no legs and can be seen as floating or levitating.
Glyde does not appear in the True Pacifist ending credits.
- Waves of star-shaped bullets are sent towards the protagonist, similar to Omega Flowey.
- Same as before, but larger, exploding versions of star-shaped bullets accompany it in-between waves, random words appearing after a huge star explodes:
- COOL
- VIBIN
- RAD
- NICEY
- SPICEY
- SWEET
- SICK
- Rarely, Glyde says one of its lines as if about to perform a normal attack, but then no projectiles appear.[3] The probability of this happening is 1%.
To spare it, the protagonist must applaud it twice and then either do "nothing" three times or "nothing" twice followed by "boo".
If attempting to fight, the first "boo" will raise Glyde's AT by 2 but lower its DF by 10.

Glyde was designed by Mike Reid as a bought-in character during Undertale's Kickstarter.[4] Reid states Glyde was originally designed with yellow eyes in its original pen sketch, but was otherwise black-and-white, like the battle sprite seen in the game.[5]
Glyde as it appears in the Stronger Monsters tarot card, titled "The World", despite not appearing in Hard Mode.
Glyde's overworld sprite as seen in UNDERTALE's 10th Anniversary Stream.
- 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 Jonathan Wojcik.
- Mike Reid describes a group of "glydes" as a fleet, stating he had airplanes and "a big flying sky whale" in mind when designing it.[6]
- Glyde's encounter method may have been inspired by the requirements to enter Belch's Factory in MOTHER 2 / EarthBound, where Ness must stand still for three minutes to enter.
- Glyde was intended to only be encounterable once. However, due to a programming error,[7] Glyde can be encountered multiple times.

I think I have an idea about where he is in the game, but his location may have changed since we talked about it. Consider backtracking!!

I was given the opportunity (through Kickstarter) to submit a design for the monster in the game and I’m incredibly proud to have it included.

i colored the eyes yellow in the pen sketch. i originally drew it with micron pens, and it ending up otherwise black & white is how i ended up imagining it as!

when i described a group of "glydes" to toby, i described it as a fleet. so i definitely had airplanes in mind. but, a big flying sky whale was probably also running through my head. i was drawing a lot of monsters at the time!
