SORROW (formerly known as B1N4RY)
Depicted as carefree and mischievous in personality. Sometimes even awkward depending on the scenario. They don't care enough to understand people but is particularly interested in interactions with humans; wishing to form a personality around these people. They are the only one who can speak English more fluent other than AGONY and DS. They're considered the main design for UTAU, wearing a red dress and torn off bright pink jacket. They have an uneven short hairstyle.
AGONY
Depicted as quiet and gentle however will not hold punches if they are threaten. Working as a nurse makes them feel obsessive to help others whenever they can. They can speak English just as fluent as SORROW however their accent spectrum is slightly British. They are shown as a nurse with wrapped bandages covering majority of their face except their polycoria eye. They have a short low ponytail.
WRATH (alternatively known as DESPAIR)
Depicted as passive-aggressive and arrogant though they are mindful who is around them. Their attitude can be almost comparable to a rebellious teenager despite being the same age as the other appends (excluding REGRET). They are shown to have a slight fancy outfit with high end socks, rebelling with majority of the usual designs. They have low ponytail. They are often seen with REGRET as a similar dynamic to siblings with them being the older sibling in headcanon. Their design may seemed similar to EL3CT0's design due to similar tones.
REGRET
Note: This append version of WH1SH-P3R excludes canon romantic relationships and is separated from canon due to their child/teen-like appearance and vocals. This is to prevent illegal usage of the voicebank and design of the character, please look into Terms of Service for more information.
Depicted as child/teen-like with a kind and naive attitude. Despite that, they've shown to be very stubborn and cling on people whenever they want which often results in situations of getting lost from home. They are seen with a blouse with a red pinafore. The only significant removal was the notable polycoria in their left eye being replaced with a hollow hole. Their hair is shown to be short and childish compared to SORROW's hairstyle. They are often seen with WRATH as a similar dynamic to siblings with them being the little sibling in headcanon.
SOLEMN
Depicted as a flamboyant and brooding for a doll featuring being half-human and rabbit. Despite the demon's vessel being the odd one out, they are very androgynous in feature. Inside of relationship headcanons, they do not associate with any other appends due to their vessel appearance making them one of the more unique cases allowing flexibility of any skin tone colour. Pale and Tan are considered the default skin colours upon depiction.
DS (DIFFSINGER) (alternatively known as DISSOCIATION)
Depicted as very cocky, reckless and flirty compared to other variants, making them the most disliked among the regular UTAU appends of the DISORDERED series by headcanon. They can speak English more fluently and mimics both types of vocals (feminine and masculine). Despite being similar as SORROW's and WRATH's appearances, they are a completely different entity that takes on a half-formal suit with a jacket. Their uneven hair covers their right eye and has a low ponytail.
