Soulwester

Appearance: A young anthropomorphic pumpkin monster. Atop its head is a stem and leaf, with a seam separating it from the rest of its head. It sports a fanged grin, and its eyes are unique in that they have black sclera and a white pupil, resembling the carved eyes of a jack-o'-lantern. It has large paws instead of hands, with four claws on each, and a long, thin tail (which is curved in-game) with a leaf at the tip. Its head, torso, and arms are orange, while its hands, feet, claws, and tail are green. Its legs fade to a darker green to match its tail, and have six thin stripes of the original green, reminiscent of a pumpkin vine.

Gordie clearly idolizes the main cartoon characters, perhaps even considering them superior to himself, as evidenced by his dialogue and gossip about them, revealing his deep admiration for them. He even has plush toys of all the main characters in his room, further confirming this. Gordie also appears polite and well-mannered, as evidenced by his dialogue, where he often addresses other cartoon characters as "Mr." or "Ms." He also refers to the main characters by their last names unless instructed otherwise, with the exception of one, although this may be due to the fact that they are the main characters of different holidays. Despite this, he tries to like Shelly, but judging by his gossip about her, he likes her less than the other main characters. Gordie is shown to be a very energetic and friendly cartoon character, passionate about Halloween. However, he is also quite insecure, constantly missing his parents, as evidenced by the drawings of them in his bedroom, his amulet, and dialogue in gossip threads. In one such dialogue, he also noted that he tries very hard to be the best face and mascot for Gardenview's Halloween events, and the expectations placed on him as the main character play an additional role in this.

Connie used to be one of the Halloween toons, but since she was so popular with the public, the management of Gardenview (where all the toons live) decided to make Connie one of the regular toons, and she was replaced by Eclipse.

Gardenview is a large in-game complex (the Gardenview Education Center and Museum) and the creator corporation (Gardenview Entertainment) where it all takes place. The complex was permanently closed on June 29, 2002, due to safety violations, unsafe work practices, and a major malfunction.

Twisteds are monsters that are corrupted, ichor-tainted versions of friendly characters (Thoons) whose purpose is to hunt down and kill Thoons.

Ichor is a black substance that causes mutation and transformation of thuns into twisteds.

(an old name by which the Halloween Tunas are sometimes called Bulinski)

Appearance: A light blue ghost with long hair that is a shade bluer than her body, a white visor, and a white shirt with black buttons, and a ghostly tail instead of legs.

Unlike other related cartoons, Soulwester's relationship with his twin sister is much worse, to the point that he even seems glad to see her less often. However, the ghostly couple still cares for each other, just like everyone else (though this is shown even less often than usual).

Appearance: A white skeleton with black eyebrows, drooping green makeup, and purple eyeshadow. She wears a jacket with purple checkered sleeves, and her chest is covered in green fluff.

Ribecca is an artist and costume designer, as per her introduction card. Ribecca loves fashion and is a kind toon, though she also appears calm, relaxed, and can sometimes speak very frankly, judging by her interactions with others. However, she is not averse to complaining, especially when it comes to car retrieval or certain toon habits.

Appearance: A blue-gray werewolf with a pink crescent moon on her forehead. Her muzzle, front of her body, tail tip, and inner ears are a lighter shade of gray, while the tips of her ears and paws are dark blue. She wears a short black scarf trimmed with pink around her shoulders. In the presence of Eclipse, her pupils constrict, she grows slightly taller, her ears become fluffier, and her smile reveals sharp teeth.

Eclipse considers other Toons to be pack members. She also howls a lot, which is likely one of the reasons for her two-star stealth rating, as Twisteds have been shown to be attracted to loud noises like her howl. This is supported by her Twisted counterpart's ability to attract other stray Twisteds. Her howling may also be a way to show her "pack" where she is, or perhaps to announce that she is finished with the Machine (which may correlate with the mechanics of her Amulet). In the elevator, her howling is used to rouse the others. She tries to lighten the mood and prepare people for the next floors. However, during a power outage, she becomes more aggressive and unstable (as evidenced by her facial expression). This is likely due to the fact that during a power outage, her werewolf takes over, heightening her hunting instincts. Her moon symbol on her forehead also seems to glow brighter during a power outage, illuminating her path and helping her "hunt" Corrupted. She also appears to grow slightly in size during a power outage. This may indicate she's becoming stronger, allowing her to run faster and longer (thanks to her increased stamina).

Appearance: A pale green ghost inhabiting armor. He wears a large gray helmet that obscures most of his face. The helmet has a visor and a turquoise gem at the base. His hair, pulled back into a ponytail, peeks out from under the helmet. His armor also consists of a breastplate, gauntlets, greaves, and sabatons, all gray. He wears a black cloth covering the unarmored portions of his torso and legs. It is currently unknown what he looks like without his armor.

Soulwester is a character who perfectly fits the image of a true knight: he speaks fluent Old English and possesses a heroic character. He even ignores claims that he is not a true knight and takes offense when his behavior is called ridiculous. He is often seen offering assistance to other characters, whether it be protection, gathering supplies, or simply general advice, but he is surprisingly quick to refuse any offer of help, which likely reflects his heroism (although he does react rather harshly when asked to remove his armor for trivial reasons). In conclusion, Soulwester may be stern and heroic, an incredibly accurate portrayal of a true knight, but there is something more behind all the armor.
