====================================

Summer is a minor antagonist in Hazbin Hotel: Journey to the Light.

She is a cat sinner who serves as one of Valentino's top employees, informants, and assistants. She is also the girlfriend of Dia.

Personality:

Summer is a seductive and resourceful sinner who is very loyal to Valentino due to his power and charisma, following any order he gives her, no matter how immoral. She always seems to be laid-back and is almost never seen without a seductive, calm cat grin. She seems to get turned on by violence, especially Valentino's outbursts.

Summer is heavily implied to be a heartless "mean girl" among Valentino's workers and acts perfidious towards her co-workers, as she is willing to rat out information about her co-workers to Valentino, even if it gets the associates into deep trouble, as she ratted on Angel Dust for getting involved in Valentino's deals, and also ratted Vox out to having paid for Angel's services without Val's prior consent.

Despite seeming very heartless and shallow, Summer does appear to at least care about and genuinely love her girlfriend, Dia; during the Vees' assault on the Hazbin Hotel, Summer and Dia could be seen protectively clinging onto each other as Alastor possessed and terrorized a large number of the Vees' underlings, and ran away with Dia to safety.

Appearance:

Summer is a feline sinner with dark orange fur, long hair, and a bushy tail. She has cat-like ears protruding through her hair and brownish-red fur on both of her wrists, hands, feet, and the tip of her tail.

Her attire consists of a choker with a bell on it and a skimpy white two-piece with a cleavage window and a yellow paw print on her bottoms.

Powers and Abilities:-

Natural Powers:

• Immortality

• Nigh-Invulnerability

Abilities

• Agility: One of Summer's most notable attributes is her cat-like agility; she is very nimble and flexible, allowing her to crawl, climb, and leap at extremely high speeds. She can use her agility to scale buildings and walls in seconds.

• Dancing: Summer is a skilled pole and lap dancer and uses her talents to arouse and please her clients.

• Stealth Mastery: Fittingly, Summer is very stealthy and quiet as a cat, eavesdropping on conversations without the participants even knowing she is there.

Relationships:

Dia: Despite having contrasting personalities, Summer and Dia are close girlfriends. As shown in their shared portraits and billboards, they lift up and complement each other nicely, and are very close. Dia is more timid, empathic, and vulnerable than Summer, who is more bold and confident. Despite their differences, they are deeply connected, frequently seen sharing affectionate moments like making out, going on dates, and enjoying each other's company. Summer often stands by and holds Dia during moments of tension, such as Valentino's outbursts, where she both comforts Dia and enjoys the chaos with a sly grin.

Summer is loyal to and protective of Dia, in sharp contrast to how she is around Valentino's other workers. During the Vees' attempted raid of the Hazbin Hotel, Summer took charge, ensuring Dia's safety by ushering her away while they clung protectively to each other amidst the carnage caused by Alastor.
