“ Cool men don't cheat on their partners. ”
—Soul Eater, Chapter 0.1

At the start of the series, Soul's personality is laid-back and nonchalant, as he tries to mold himself to his expectations of how someone 'cool' would act. He is almost the complete opposite of Maka, being calm, reserved and aloof. He often expresses how he feels about some situations by either claiming that something is 'cool' or 'not cool.' Being a supposedly cool guy, he prefers to use the direct approach which most of the time fails (although after maturing, he no longer does this). He has a unique love for eating souls that seems to not be shared by many of the other Weapons, drooling quite frequently when his next meal is nearby. He also seems to be a glutton towards food in general. He can sometimes become too driven by the thought of eating souls, which leads him to bicker with Maka or become impatient with her, but despite their squabbles, they are always able to maintain a solid friend-partner relationship. He is also friends with Black Star because of their similar personalities, but at the same time they cannot match their Wavelengths. He is slightly immature, being headstrong, stubborn, apathetic to most things and argumentative. He also has a strong weakness towards women, as he bursts into a nosebleed without fail every time he sees Blair naked. He is also a slacker that likes to find an easier way out of situations, shown when he attempts to cheat in a DWMA exam.
However, one thing he has gained from all the years of being 'cool' is he is possibly one of the most loyal people one could possibly meet, especially since breaking promises and changing sides 'isn't at all cool in the least.' Deep down, he is always looking out for his friends, and is even willing to sacrifice himself in order to protect his partner, Maka, showing his bravery and dedication. Despite his usual unenthusiastic appearance, he proves to be actually quite determined, and he also helps people get back on their feet when they are at a loss. He is also quick-thinking and cunning at times.

After the rise of Asura, however, Soul's personality greatly matures (mostly because of his awareness that he must grow stronger to combat the strong insanity released into the world), and his stubborn and headstrong demeanor is replaced by a more cool-headed and serious one. He remains remarkably calm and composed no matter how dire the situation is and has impressively deep insight on various situations and people, often noticing important points no one else had thought of. He also shows a good deal of sense and judgment, which is well-respected by his peers. He begins to show more awareness and understanding towards people, up until the point that he even lectures some of the other characters when they are too stubborn to see some situations clearly, although he sometimes thinks it best to leave people to figure things out on their own. Since he is infected by the Black Blood, he runs the risk of being overcome by madness. Because of Soul's constant grapple with the Black Blood and Little Ogre inside his soul, he has a good degree of self-control as well, and rarely gives in to his emotions. He has demonstrated extremely strong willpower, being able to hold onto both his and Maka's sanity whilst using the Black Blood against Crona. He still has a compassionate side, proving to be a good loyal friend to others, and is still willing to do anything he can to protect his Meister.

However, he seems to suffer from low esteem and is not confident in himself. He is saddened of his inferiority to Weapons like Justin and Giriko and cringes at the thought of his brother, Wes, who is a superior musician to him. He also conflicts frequently with Little Ogre in his mind. He keeps most of these problems to himself, and seems reluctant to share his problems with others, which sometimes makes him appear harsh and almost cold. He is mostly seen frowning or scowling, and most of his smiles are somewhat sarcastic. He is rather pessimistic, and is slightly aloof and detached from others, and he admits that he shares Crona's fear of bonding with people. At the DWMA anniversary party, he is seen outside on the balcony by himself rather than with the others, and does not tell Maka of his Black Blood infection and his dreams of Little Ogre, although this is mainly because he does not want to worry her. He still has a kind-hearted side, although he shows this side the most to Maka.

In the first Chapter of Lust in the Book of Eibon, Soul's personality undergoes a bit of a change to suit his switched gender. Although sarcastic as he usually is, he is also a little stuck-up and haughty, and his behavior goes on to annoy his partner, Maka. His personality returns to normal after leaving the first Chapter. He quickly reverts to his true male appearance alongside Maka, which means he does not possess much lustful thoughts (which is ironic because of his constant nosebleeds upon seeing Blair's naked body).
Soul also has a talent for playing the piano. His Meister, Maka, reveals that when they first met he played a dark song for her on the piano. Apart from this however, he is reluctant to play in front of people as he 'doesn't know what he's capable of.' The reason for his talents with the piano is that he comes from a family of musicians. His brother, Wes, is a famous violinist. However, Soul wanted to break off from his family tradition of being a musician. When he found out that he was a distant descendant of weapons, he used his ability as a excuse in order to leave his family. Soul also claims that the songs he plays on the piano are ones of madness. However, his love of music still remains, and he seems to open up a little when it comes to music. He has good musical taste, and personally seems to like jazz music. He also seems to have an eye for architecture (he claims that Blair's pumpkin house is 'cool' and later says that he likes Gothic architecture).
When Stein sees his soul, he evaluates that Soul has a, 'twisted and sarcastic soul.' Soul sometimes shows a dark and sarcastic sense of humour, that usually annoys most people, especially Maka.
