Chasmacrocuta is a weird, slightly anti-social, but surprisingly clever skeleton hyena. She struggles with social situations and pretty much hates everyone except Soot. She rarely communicates with anyone else. She can always be found with Soot, unless unable to, in which case she is on her laptop or playing the piano/violin. She doesn't seem dangerous, and at most times won't be and won't really care. She doesn't really care about anyone except Soot and will protect him fiercely.
- Chasmacrocuta lives in a hard-to-find area above Hotland that is savannah-like. Many monsters that are similar to surface-dwelling savannah animals live there. She dislikes Hotland and the savannah, so wants to move somewhere better with Soot some day.
- She was born on the surface, and lived with hyenas and hyena monsters. She fought for monsters when the war came. She would brutally kill any human who went near Soot, keeping him close as possible, trying to make him hide instead of fight, keeping an eye on him at all times.
- When the war was over, Chasmacrocuta's family and friends (most had survived) came back with Chasmacrocuta. She was wearing a long glove for some reason, everyone suspecting it was because she had a wound that didn't look nice, so they didn't mention it. Ever since then, she became more secluded, becoming more exclusive to Soot alone, and her glove turned into clothing covering her chest and neck, and it went on until she just went around in a blanket. No one suspected much then, because it's just a weird thing she would do. Only his tail would show through the blanket for some time, until that was hidden too.
- One day, one of her remaining friends, Fisi, accidentally tripped on her blanket, knocking it off. Chasmacrocuta had slowly been turning skeletal, and had tried to cover it, keeping the information known to no one else except Soot. Chasmacrocuta does not really remember how, or any of the war at all, but it is suspected she was killed, and a spell made her become some sort of undead.
- Her family and friends are ok with his being a skeleton, but that does not concern her. Her only fear about her appearance is that Soot doesn't like it, even though he does. Chasma enjoys being a skeleton, but wants to find a way to be a normal hyena again so she can be fluffy as Soot enjoys fluffy things.
- If he was in the pacifist credits, she would go down the same highway Sans and Papyrus go on, on a skateboard (even though she dislikes them), wearing sunglasses and listening to a player with earphones. Soot would be in a helicopter that looks like a piano above her.
- If Papyrus is killed, soon after killing him the player will encounter a hyena skull (controlled by Chasmacrocuta), which will ask them why they did it. It will explain that Papyrus is so innocent, and something was wrong with them because they killed him. If the player has killed him in a genocide route, the skull will explain how they're just doing this because they don't care about these characters and they are murdering out of amusement and curiosity. The skull, in any route Papyrus is killed, will then blast their SOUL with a rainbow beam, lowering their HP to 1. The skull then disappears.
Chasmacrocuta wears a green top/hoodie with a zip and small bone and heart logos on it. She always has it unzipped, showing her red-orange shirt. She wears blue-purple trousers. She is completely white (because she's a skeleton) and her eye sockets have white pupils. Her eye will glow rainbow once enraged, and if someone somehow touched it, it would burn worse than a laser. In the genocide route start and (very) unsafe neutral route, she will have his rainbow eye. In the genocide route, when the player chooses the "FIGHT" option, it will do 1 damage, and then she will take her genocide form. Damage on her will increase with every hit. Her fangs will look sharp and her "ears" will be ripped. She has an expression of pure hatred, a red glow in one eye socket, and her other eye will be rainbow and glow. There is a crack down the forehead of her skull. She has armour, similar to Undyne the Undying's armour, that has an orange tint and the shape of a monster SOUL. She will hold two bones instead of one, and has shading on her.
Description - if in battle with Soot
When the player attacks Chasmacrocuta's area in the genocide run, they can either give Soot the time to run away (does not stop genocide run) or attack him. If Soot is attacked, Chasmacrocuta will block the player's first attack by jumping in front of Soot, and then taking on her genocide form. Soot also takes on a genocide form, and the player must battle both of them. The battle will include both of their attacks. If the player attempts to hit Soot, Chasmacrocuta will block it with bones. The player has no choice but to just attack Chasmacrocuta. Once Chasmacrocuta's HP is wiped out, she will seemingly go insane and shout at the player, saying random things that don't make sense, and telling Soot that she loves him. She will eventually seem to explode into dust, but permanently shields Soot. The battle will end, as Soot is so distraught at Chasmacrocuta's death and knows he can't avenge him if Chasmacrocuta was not strong enough to beat the player. Soot goes into hysterics and blindly attacks the player's soul, possibly killing it if attacks are not dodged, then eventually he runs out of energy and realises he cannot do it.

- Meiaenu (mother)
- Crocukuto (brother)
- Tsuki (sister)
- Echo (sister)
- Katana (aunt)
- Apologise/plead (lowers Chasmacrocuta's attack, as she is sympathetic)
- (Note: above does not help if she is fighting someone who killed someone she cared about)
- Talk (will end fight earlier in a pacifist route, because Chasmacrocuta likes discussing video games)
- Flirt (attacks decrease due to awkwardness)
- Chasmacrocuta throws (yes, throws) bones at the SOUL. If the SOUL gets hurt on a pacifist route, Chasmacrocuta will awkwardly apologise and throw bones away from the SOUL the next turn.
- Paw prints appear on the bullet board, and when claws appear it is a warning that the paw is about to suddenly get bigger. Chasmacrocuta will only use this attack once in a pacifist route.
- Fangs, bones, and claws drop from the top of the bullet board randomly. Attack is used multiple times, unless the SOUL gets hurt a lot by the attack on a pacifist run.
- Hyena skulls will spray a rainbow from its mouth and eyes. There is a specific way of dodging.
- The SOUL will be controlled by Chasmacrocuta, and she will smash it into the sides of the bullet board randomly. When the SOUL hits the sides, it can control itself temporarily, to avoid bones that Chasmacrocuta throws at the SOUL. This attack will only be used in a genocide run and some neutral runs.
- Rainbow SOUL mode: There are seven lines, each in the colours of the rainbow, that the SOUL can move to. Bones will drop from above, hurting the soul, but it can move onto another line to dodge. If the SOUL moves onto another line with a bone over it, it will smash the bone, dealing no damage to the SOUL.
Chasmacrocuta will be extremely careful not to hurt the soul too much on a pacifist and some neutral runs. If the soul reaches 1 HP, she will spare. Chasmacrocuta will not spare at all if five or more non-boss monsters have been killed, if 3 or more mid-bosses have been killed, or 2 or more bosses have been killed. If one of her friends or family is killed, she will use brutal attacks and insults. She cannot be killed in the pacifist/safe neutral route, due to her high HP and there not being enough turns to kill her.
