Death the Kid

Described as possessing an "uptight personality" by Franken Stein, Death the Kid is known to be a normally calm and mature individual compared to those like Black☆Star and Soul Eater. Throughout the series, he's shown to be prideful of his status as a Shinigami, wanting to become the next full-fledged Shinigami and inheriting his father's responsibilities However, he also wants to do so in his own unique way, even telling his own father he wants to makes his own weapons to his specifications despite Death infomring him that as a Shinigami, he doesn't really need to collect souls. According toBlack☆Star's testament of his view on Death the Kid, despite being a Shinigami he is also capable of being humane and not displaying the typical arrogance of someone who has the status of a god. This is true, so much so that he even see's himself partly as a human and expressed this fact to Asura.

Kid also has a great sense of morality and order, having expressed to the Flying Dutchman that despite being a god, he doesn't deny evil and that there's no one person without some evil within them. However, he believes that everything is about balance instead and strives to keep the balance between "good" and "evil" in equilibrium. When expressing this, he also informed the Flying Dutchman that cares little for other's view on the subject and strives for a "absolutely" perfect world, granting no one freedom to kill. Kid's view on balance is partly due to his father's teachings to him on order as a child. Despite favoring order, he also aware of not following it blindly. He's quick to question his own father's actions when he had Shibusen storm into Baghdad when searching for Asura and explained that it's wrong to impose their will on others, though was understanding and sympathetic of his father when he realized that due to the threat of Asura, his father doesn't have the luxury of "playing it safe" and may be reckless in his decisions. When the majority of Spartoi was ordered to execute Crona, Kid was the only one who supported the action, citing that Crona's actions were unforgivable and even alluded that the reason why they were ordered to do so by his father was for them to decide how to face Crona but said that both them and "order" must move forward to take care of the threat Crona possessed.

Kid is also extremely humble, shown when he pleaded to the Witch Order, the Witch Judge, and the Witch Queen to assist Shibusen in stopping The Clowns and pushed for both Humans, Witches, Shibusen, and the Witch Order to have better relations. He also put good faith and trust into the Witch Order, despite the protests of Azusa Yumi. He also explained to Azusa that merely holding ideals means nothing and one must realize that people must make an effort to make things better and that If being an adult means "stapling out ideals" because of experience, he doesn't mind being called "Kid". Because of his views, Azusa comments that he is also pushy, much like his father.

Like his father, he also has a fierce and more darker side in his personality. While normally calm and collective, Kid is still susceptible to being angered, such as when Mosquito insulted his fathe and when Noah's Group announced their plan to assassinate Maka Albarn, he showed much anger. When he later faced Noah (Greed) on his plans of "replacing the gods", Kid even gave him a death threat, in which was guaranteed when he used the Parent's Seven Raysattack on the Sorcerer, killing him.

Despite his great capabilities, Kid also possesses some flaws, most notable him being a perfectionist. Described as being "too much of a perfectionist", he initially was very obsessed and concerned with orderliness and paying excessive close attention to detail so much so he complained about Liz and Patty's breast size being irregular, chose them as weapons due to their twin appearance, and even refused to attack the Wrath of the Pharaoh due to symmetry as well as disliking the fact his Lines of Sanzu were incomplete and upon Liz pointing it out, he called himself an ugly pig and worthless piece of garbage until he was quickly cheered up by his fellow weapon partners. He is even physically repulse of unsymmetrical arrangement to the point he almost vomited at the sight. Due to his wanting to be precise in detail, it even took him over a month to help Liz pluck her eyebrows as well as failing an entire test due to being unable to correctly write his name symmetrically and accidentally ripping the paper while erasing after being reduced to tears, causing him to cough up blood and was knocked out. He also let Crona and Ragnarok get away to admire the sky and it's symmetry. Despite taking counseling lessons, it remained as a fatal and dangerous flaw. Even the mere sight of something unsymmetrical causes him to become more aggressive, not only killing the Wrath of the Pharaoh in a fit of rage, but also Pyramid Anubis due to his recklessness. In actuality, this part of his personality is a manifestation of the Madness of Order due to being a part of Death himself, a fact he himself is unaware of.

Despite this flaw, he is noticeable not unaffected by his father's appearance despite it being unsymmetrical possibly due to his immense respect for him. This is a bit more evident when Kid was shown to even willingly sport the same robes of what his father wears on missions. As time passes throughout the series (sans the anime), he becomes less affected of his perfectionist nature and matures enough to accept it, though will still occasionally bicker over small details. This remains true even when he became a true Shinigami.

Kid has his own, odd quirks. His favorite number is eight due to it's symmetry and according to Liz, was willing to try and place himself in exactly eight seconds during a 100 meter dash test and end up not meeting the time. He can also be somewhat overconfident in his ability, feeling the need to not study Soul Studies just because he was a Shinigami.Due to his perfectionist personality, he is the type of person to recall and correct people on the small of detail, pointing out even when infect by the Madness of Power to Black☆Star he never punched him and used his heel during their fight when Black☆Star erroneously stated he punched him into submission, something the assassin noted to be something unique to Kid.

While under the influence of the Madness of Power, Kid's personality changes dramatically due to his yearning for the perfect world. However, instead of balance, he strives to achieve "nothingness". He is willing to even kill an individual by using the power of "nothingness" to send a person to "nothingness", a flawed and somewhat absurd logic as pointed out by Black☆Star. In addition, unlike his typical personality, he also becomes arrogant, seeing himself as above others due to being a Shinigami.
