List of characters

This is a list of characters who appear in Celeste. Not all characters have yet been added here, so if you see one who isn't here, feel free to add them!

Madeline

 * Main page: Madeline

Madeline is a 21-year-old red-haired Canadian woman. She is determined to climb Mount Celeste, despite opposition from others including herself. She is the only playable character in Celeste, apart from a brief minigame.

In the Prologue, the Bird tells Madeline how to move and climb, as well as saving her from a collapsing bridge by teaching her how to dash. Later, in Chapter 6, Madeline gains the ability to dash twice.

Theo

 * Main page: Theo

Theo is an American man of Brazilian descent. He is also climbing Mount Celeste, though unlike Madeline he isn't aiming for the summit. Compared to her, he is more laid-back and doesn't have the same internal struggles--however, he does have a reason for leaving his job to climb the mountain.

Theo appears time and time again throughout the game as a supporting character. The player is able to talk to him each time and watch Madeline gain a friendship with him.

Badeline

 * Main page: Badeline

Badeline, referred to in-game as a Part of Madeline (Part of Me/Part of Her), is an aspect of Madeline's mind that gained her own body in Chapter 2. She plays an antagonistic role throughout much of the story, chasing Madeline and breaking gondolas in hopes of stopping her from climbing the mountain.

She is playable, but only through the Other Self option in Variant Mode.

Granny / Celia

 * Main page: Old Woman

Granny is one of the few people to live on Mount Celeste. She has a cabin at the very base of the mountain and appears occasionally to guide Madeline with her knowledge of the mountain, but how she manages to appear everywhere is unknown. Madeline does not initially enjoy how she talks to her. In Farewell, if you look closely at the picture Theo sends Madeline, you could read "Celia & Carlos" written in cursive, stating that her real name is Celia.

Mr. Oshiro

 * Main page: Mr. Oshiro

Mr. Oshiro is the deceased owner of the - now defunct - Celestial Resort and mostly appears in Chapter 3. When Madeline comes to the resort, he is cordial towards her in hopes of getting her to stay there. Granny describes him as a "lost soul".

Bird
The Bird is a blue, crow-like character. The Bird's usual purpose is either to teach the player a new gameplay element in Celeste, or to herald the arrival of the Old Woman (as the Bird is often found near her).

In the Prologue, the Bird first teaches the player how to move and climb, then saves Madeline from falling into a chasm by teaching the player how to dash, allowing Madeline to make it to the other side safely. The Bird later appears near the Old Woman in Chapter 4, Chapter 6, the Epilogue, and Chapter 8, as well as appearing on its own in Chapter 2's B-Side (to teach the player that they can jump out of Dream Blocks), Chapter 7's B-Side (to teach the player how to wallbounce), in Chapter 8's C-Side (to teach the player how to do a hyper), and in Chapter 9 (to teach the player how to wavedash).

It plays a major role in Chapter 9, where Madeline continually chases after the bird believing it to be part of Granny, and that catching it is the only way to find her.

Alex
Alex is Theo's sister, who he describes as a "rockstar" and having a very good sense of what she wants to do in life. She is studying to become a civil rights lawyer while also struggling with issues similar to Madeline; Theo hopes to support her as best as he can.

If you name Madeline Alex at the beginning of the game, Theo refers to her as Maddy instead.

When Theo mentions Alex's name, the text is red, the same color as when he mentions Madeline's name.

Carlos
Carlos is Theo's deceased grandfather, who had climbed Celeste Mountain long before his grandson was born. He never talked much about the mountain to Theo, but did leave behind various mementos that Theo and Alex look through. He was friends with Granny at an adult age.

Green-haired Person (Madeline's ex)
Never referred to by any name, the green-haired person makes their one and only appearance when Madeline tries to call them in her dream. The way they speak to Madeline implies the two of them dated at one point, but have since broken up. They have not spoken to her for a long time in real life.

Mommy
Madeline's mother only appears once in-game, listening to Madeline over the phone after the latter wakes up from a nightmare. In general, she is aware of what Madeline struggles with and tries to support her, but isn't quite sure how. She knows that Madeline gets depressed and has panic attacks, with a panic attack seen in Chapter 4: Golden Ridge.
