Crona

Described by Franken Stein and his Soul Perception to have an "introverted" personality,[10] Crona is pessimistic and doesn't hold a high opinion of themselves.[11] Due to being raised by Medusa Gorgon, they are extremely negative as well as nervous and submissive most of the time, playing a part of their bullying from Ragnarok.[12] Possessing a great amount of shyness, Crona cites they're unable to "deal" with many things, whether it pertains to a situation, an action, or a specific individual. This causes them to complete shut themselves down from their surroundings. Perhaps what makes Crona a dangerous enemy is their unbalance state of mind and inclination to insanity (Madness mindset). This unbalanced state of mind originates from not only the influence of the Black Blood's Madness, but namely the abuse they suffered from the likes of both Ragnarok and Medusa as she drilled and tortured them into learning the ability to kill. Because of this, Crona is subjected to showing signs of insanity and aggression, spouting senseless comments and laughing at random moments[14] This level of abuse has caused them to gain a warped objective of attempting to become an Kishin in an attempt to be able to "deal" with any given subject as well as fulfill Medusa's goal and gain not only her acceptance and love but to avoid being abandoned by their parent.[15] Of their own admittance, Crona doesn't understand the concept of morality.

After meeting Maka and their enrollment into the DWMA, Crona stated showing more positive traits and was capable of feeling the need to protect Maka, who was previously their enemy.[16] Their placement within Death City and DWMA caused Crona to become relaxed and happy in demeanor.[17] Much of this development was lost due to some sort of amnesia when Medusa re-integrated their Madness mindset after capturing them back into her ranks.[18] However, Crona gained much of themselves after Medusa's passing and capture by Asura, reflecting on their actions and finding it unforgivable. In a final heroic turn, Crona even opted to seal themselves with the Asura with the usage of the Black Blood and "BREW" for the sake of Maka as well as the entire world.[19] In the anime, their re-integration of their Madness mindset doesn't take place as Crona developed enough confidence within themselves to come to terms of Medusa's incapability to unconditionally love, recognize her cruelty and rebuke it, and even integrate themselves into DWMA's school culture. Crona themselves possess some quirks. Their negativity has enough "destructive power" to write a poem able to evoke others to regretting their existence, even those as obnoxious as Black☆Star or the undead like Sid.[20] Crona also has the tendency to redundantly remind others of having Black Blood in battle. Due to their shy and nervous personality, Crona has a knack for naming parts of rooms such as "Roomsky Kornerkov" (Mr. Corner in the anime)[21] as well as having shuffling footsteps in general.

Physically, Crona possess an androgynous appearance with a thin body, pink hair, lavender eyes, and tall stature. Their hair is quite short with several long, large clumps, bangs straight-cut and end above the eyebrows, but do not stay very uniform. Two long pieces of hair extend from the bangs and hang low over Crona's face. Crona's attire consists of a long black old-style robe that is tight-fitting and ends at the mid-calf level on their legs. The robe is completed with large white cuff-links at the ends of each sleeve and a tall white button-up collar at the neck. Black slipper-like shoes with a tall white cuff protruding out of the top are also worn.For formal occasions, Crona wears a white suit: the suit is very plain, with long pants, a coat with long sleeves and a collar. The coat appears to fasten at the front and back. Crona's soul in hitomi form appears as a normal, lighly colored soul. When expanding, the soul appears in a darker tone. As a child, Crona wore a black knee-high dress. The dress has a rugged cut-out at the bottom, laced with several white diamonds. Like the present-day clothing, the childhood design also has a white collar and cuffs. The shoes stay relatively the same, as well. Crona's hair is shorter and simpler in this stage, but overall the same design. Also, Crona possessed large pupils.
