PERSONALITIES

Clover - he is basically a silent protagonist

Martlet - Martlet is shown to be, as the game states, scatterbrained. Martlet seems to struggle with concentrating on her duties and often relies on a manual or lists so she can know what she has to do. Her laziness is also hinted at in the game with a note on Information booth that tells passerby to wake her up if she dozes off on the job.

Starlo - Starlo's true personality is superseded most of the time by a Western persona. Borne out of a fanaticism of Wild Western culture, Starlo puts on this persona from a desire to spread excitement and drama to the inhabitants of the Underground - distracting them from the cruel reality of monsterkind's collective banishment from the Surface. Going by the moniker of "North Star," he plays the role of the Wild East's upbeat sheriff, who is determined to "keep the peace" by any means necessary. This for the most part is all drama, as there is no real danger (besides potentially Clover) and is all put on as a fun distraction for the Dunes' inhabitants, who all seem to play along.

While displaying his "North Star" persona, Starlo has been shown to value validation from others. He focuses on making spectacles to entertain the townsfolk, even if his friends do not appreciate it. This is also the reason he eventually attacks Clover; to be revered by the entire Underground.

Starlo's true personality is revealed after his boss fight in the Pacifist Route. He is shown to be much more of a nerd - a picture in his home revealing he was even adorned with stereotypical dweeb braces at one point. As such, his room is filled with various Western memorabilia from the Surface and even contains glowy sticker stars. Despite this, however, one thing that is constant between "North Star" and Starlo is his kindness and how he values those close to him. In fact, this is the whole reason the "North Star" persona exists in the first place.

Ceroba - Brilliant, supportive and skeptical, Ceroba is a powerful ally when it comes to wanting to help those closest to her. She is shown to care a lot for her loved ones. However, she is highly stubborn, even going so far as to question the true meaning of Asgore's words when confronted with the truth of her husband's employment. Because of this, she is firm on her husband's legacy as a scientist and a hero of the underground, and she spends the days after her husband's passing trying to complete the work that he had passed down to her. However, when she finally tests it on Kanako and has it result in her falling down, Ceroba's beliefs strengthen to the point that she is fully willing to kill Clover to save the rest of the underground.

Ceroba is observant, and can tell how others are feeling just by a glance, and can also notice a shift or change in the other's moods. Though she is not hesitant to say them to others, she will try to hide them from those she loves as long as it does not harm others. An example of this is her relationship with Starlo, and she didn't confront him about his behavior until after his friends had come up about how it was making the rest of them feel. She is quite honest and straight-forward as well. This is evident from how she treats Starlo's shenanigans in the Wild East, saying she doesn't understand it and acting nonchalant when included in them, as well as her realistic assessment of Clover's fate before and after her battle in the Pacifist route. The exception to her realism is her husband, Chujin, who she always holds in high regard no matter what information is displayed to her that may say otherwise.

Dalv - Dalv is socially awkward and claims to desire solitude. He often monologues about how he sent the other monsters away and how he wonders if they ever really cared about him, and is consistently interrupted by Clover. Despite that, he later reveals that he does not actually want to be alone, but rather fears that any friends he makes will leave him behind the moment they grow tired of the Dark Ruins. When hanging out with Clover, he seems very happy to have a friend to talk to. His interests include writing and illustrating children's books, playing the organ, and growing vegetables (especially corn).

Axis - Though he may seem an unsophisticated robot, Axis is a sentient being shown to experience intense, complex emotions. He is short-tempered, easily flustered, and evidently quite foul-mouthed (though his swearing is replaced with milder language by what appears to be a profanity filter). He is also capable of experiencing love; when presented with a 'companion robot' Clover and Ceroba built to distract him with, he becomes besotted with it and declares it his spouse. He also greatly misses Chujin, for his late creator was kind to him. In the Genocide Route, Axis expresses remorse over killing the previous fallen human.

The Feisty Four - Ed is a fearless and tough monster. He is also the most temperamental character in the posse, but he recognizes it and states that he wants to work on it. In addition, he wants to learn how to play the guitar, but due to him being bigger than the others, he can not play it. Ed is the first one to speak up for the group and tries to deliver justice when Starlo leaves the Feisty Four and Clover alone. Furthermore, he is optimistic and apologizes for his actions, as he tells Clover he is sorry for being so forceful earlier when they arrived at the Wild East.

Moray represents the E and Y in Feisty, being Excellence and Youthfulness respectively. They are the only member of the four (without counting their boss) that is known to keep contact with their parents. Moray is also more caring and sympathetic towards Martlet, as they bring her food even though it is not mealtime. They are also the one that stays more in-character when the posse are acting for a mission for Clover in comparison to some of the other members. When the group wishes Clover and Martlet good luck on the Pacifist Route, Moray is the last to leave, giving the pair one last look before departing, showing that they really got attached to the two. In addition, they have a passion for music, as in the neutral route they are seen playing the guitar on the saloon.

Ace is the most serious member of the posse. Due to this, he is seen reacting to the other three shenanigans with face palms at the end of the true pacifist route. But this does not mean that he joins as well at some of the adventures of the Feisty Four. As Blackjack states that he and Mooch installed the speaker system throughout the town, using it to play an eagle screech and play jingles and songs. Ace is also the one that represents the I in feisty, this letter representing intuition. He also describes himself as “2D as my cards” but doesn’t seem to be bothered by that. Moreover, he notices smaller details, like for example, when Clover’s hat was practically decomposing before the duel.

Mooch is the only one in the group that commits crimes, this being pickpocketing and thievery. She is sneaky and is the representative of the S in Feisty, which stands for Sneakiness. As Ace stated, she is the only one that never oversteps her boundaries. She likes shiny items, as she remarks that the gun that North Star gave to Clover is awfully shiny. Mooch sometimes makes sarcastic remarks, since she tells Ace to not be so kind when he doesn’t even ask for her help in the Feisty Four battle. Despite this, Mooch can be kind when she wants to be. If Clover kills Starlo and returns to the Wild East, Mooch is seen in front of the Five's house and apologizes on behalf of the group if she is talked to. It is also implied in the neutral route that Mooch is the youngest member of the posse, since Dina doesn’t let her sneak a drink.

Dina - Much like the other residents of the Wild East, Dina has the demeanor of a stereotypical Western character, frequently saying howdy among other things. She's also far more relaxed than many other characters, not holding any ill will towards Clover in the Neutral/Pacifist route. Like most other vendors, she gets slightly annoyed when Clover attempts to sell items to her, helpfully informing them that Blackjack might buy the items instead.

She seems to have a soft spot for animals, adopting snakes named Ann, Sammy and Bert that she says she found in crevasses in the Dunes. She mostly has them to keep her company while business is slow in the saloon. Despite other monsters thinking it's weird to keep pets, she instead finds it to be cute.
