Sid Barrett (Soul Eater)

Shaula Gorgon — Sid's killer
Shaula holds a particularly dark importance in Sid's story.
In the canon, Shaula Gorgon is responsible for Sid's death, who is later resurrected by Stein as a zombie.
Neo Encyclopedia +1
In their version of the story, this could be transformed into one of the character's most important moments.
Sid could confront Shaula to protect the students.
Even knowing he couldn't win, he would keep fighting to give the students time to escape.
This would be an excellent connection to Sid's later transformation into a zombie.

Medusa Gorgon — enemy
Sid considers Medusa Gorgon an extremely dangerous threat to the students.
He doesn't trust her for a second.
For Sid, Medusa represents exactly what a Shibusen professor needs to prevent:
someone willing to use children and students as tools for their own experiments.
Relationship: enemies.

Mira Naigus — partner in arms
This is a particularly important relationship for Sid.
In the Soul Eater material, Sid is a meister and his weapon partner is Mira Naigus. His fighting style is primarily associated with the use of knives and assassination techniques.
Soul Eater Wiki
Mira is much more practical and organized.
The two work well together because they compensate for each other's weaknesses.
Sid is all about strength and improvisation.
Aim is about precision and strategy.
In combat, the pair is extremely dangerous.
Relationship: partners in arms and meister; very close professional companions.

Spirit Albarn / Death Scythe — long-time companions
Sid and Spirit Albarn have a very long history.
The two participated in Shibusen operations and were involved in the operation against the Star Clan.
Neo Encyclopedia
Sid respects Spirit as a warrior, but often loses patience with his womanizing behavior.
When Spirit starts talking about women, Sid simply walks away.
Relationship: battle companions and friends.

Patty Thompson — the student who confuses Sid the most
Patty is one of the few people capable of leaving Sid completely speechless.
She might show up during a training session carrying something absurd and simply ask:
"Professor Sid, will it explode?"
Sid:
"Probably."
Patty:
"Legal!"
Sid:
"...It wasn't an invitation."
Despite this, he genuinely likes her.
Relationship: teacher, protector, and friend.

Liz Thompson — trust and protection
Sid considers Liz to be an intelligent young woman who is extremely useful in dangerous situations.
He also realizes that she tries to hide her fears behind a more mature and sarcastic personality.
Since Liz and Patty came from difficult childhoods, Sid develops a very protective attitude towards them.
Relationship: teacher and protective figure.

Death the Kid — respect among warriors
Sid has enormous respect for Death the Kid.
Because he is the son of Shinigami-sama and possesses a different nature from the other students, Kid catches Sid's attention.
Sid also enjoys provoking Kid's obsession with symmetry.
He might deliberately place two crooked objects on a table just to watch Kid fall into despair.
Despite the jokes, Sid acknowledges Kid as one of Shibusen's greatest talents.
Relationship: teacher, ally, and friend.

Soul Evans — the student Sid provokes
Sid likes to tease Soul.
He finds the boy's relaxed manner amusing and realizes that Soul is trying to hide his insecurities behind a "cool" attitude.
Sid, however, knows that Soul has great potential.
When Soul starts to doubt himself, Sid usually says:
"Being cool doesn't mean never feeling afraid. It means continuing to fight even when you feel afraid."
Soul comes to respect him a great deal.
Relationship: teacher, mentor, and student.

Maka Albarn — exemplary student
Sid has great respect for Maka Albarn.
He recognizes in her a characteristic that he considers extremely important: discipline.
Maka, on the other hand, finds Sid frightening at first, but quickly realizes that he genuinely cares about the students.
Sid often reprimands her when she puts herself in unnecessary danger.
He also recognizes the strength of the bond between Maka and Soul, as the two possess an exceptionally strong soul resonance.
Soul Eater Wiki
Relationship: teacher and student; mutual respect.

Tsubaki Nakatsukasa — respect and friendship
Sid really likes Tsubaki.
He realizes that she is one of the few people capable of controlling Black☆Star's exaggerated behavior.
Sid often jokes:
"Tsubaki, you deserve a raise for taking care of him."
Tsubaki considers Sid a reliable figure and often seeks his advice when Black☆Star is going too far.
Relationship: teacher, friend, and sort of spiritual daughter.

Black☆Star — adopted son, student, and greatest responsibility.
This is the most important relationship in Sid's life.
After the destruction of the Star Clan, Sid found the baby Black☆Star. Instead of killing or abandoning him, he decided to take him to Shibusen and help him grow up.
Soul Eater Wiki +1
Sid never treated Black☆Star as just a surviving child.
He taught him:
discipline;
fight;
responsibility;
control of the soul;
respect for teammates;
The difference between strength and arrogance.
Black☆Star grew up seeing Sid as practically a father figure.
Therefore, despite Black☆Star being extremely loud and conceited, there is one thing he takes very seriously:
Sid's opinion.
Sid is also one of the few people capable of making Black☆Star stop talking and actually listen.
Relationship: adoptive father, mentor, teacher, and son.

Franken Stein — best friend and battle companion
Franken Stein is probably the colleague who knows Sid best.
The two worked together on extremely dangerous missions and participated in the operation against the Star Clan. In canon, Stein was part of the team that eliminated the clan.
Neo Encyclopedia +1
Sid and Stein have very different personalities:
Sid is direct and impulsive;
Stein is analytical and eccentric;
Sid trusts his instincts;
Stein trusts analysis.
This generates constant discussions.
Stein questioned Sid's decision to take baby Black☆Star to Shibusen. Sid ignored the recommendation and decided to raise him.
Soul Eater Wiki
Despite their differences, the two share a deep friendship.
Relationship: best friends, battle companions, and brothers in arms.

Shinigami-sama / Lord Death — superior and friend
Sid has a relationship of great respect with Shinigami-sama, the director of Shibusen.
Shinigami trusts Sid because he is a teacher who puts the safety of his students above his own. Sid, in turn, doesn't treat Shinigami merely as his boss: he considers him the man responsible for maintaining the balance between humans, weapons, witches, and Kishin.
Sid is also one of the few teachers who can speak directly to Shinigami when he believes a decision puts the students in danger.
Relationship: friendship, respect, and professional trust.

After overcoming his condition, Sid officially began working for Shibusen.
At first, many students were afraid of him.
Some even came to believe that Sid was a creature sent to devour them.
Sid simply replied:
"If I wanted to devour you all, the class would have already ended."
The phrase quickly became something of a legend among the students.
Over the years, Sid became known as one of the most resilient professors in academia.
He wasn't necessarily the most skilled.
Not even the fastest.
But few could continue fighting after taking a hit from him. The relationship between Sid and Soul Evans started off complicated.
Soul initially thought Sid was overly serious.
Sid, on the other hand, immediately realized that Soul possessed enormous potential, but also a dangerous tendency to hide his insecurities behind a laid-back attitude.
During a training session, Soul asked:
Professor, do you always have to look so scary?
Sid looked at him.

• No.
  Soul smiled.
  Then why do you do that?
  Sid replied:
  Because it works.
  Soul remained silent for a few seconds.
  — ...Fair enough.
  Despite the provocations, Sid came to respect Soul.
  He realized that Soul possessed an extremely important characteristic:
  He was able to trust another person.
  For Sid, this was essential for someone working in tandem with a Meister.

Before becoming a teacher at Shibusen, Sid was a field fighter.
He was sent to various regions of the world where Kishin Eggs, witches, and creatures corrupted by insanity were emerging.
During one of these missions, Sid encountered an entire community dominated by a creature that had begun consuming human souls.
The creature wasn't powerful enough to be considered a Kishin, but it was close.
Sid managed to defeat her.
However, during the fight, an explosion of spiritual energy struck his body.
His soul was partially contaminated by the creature's residual energy.
From that moment on, her body began to change.
Her skin turned blue.
His eyes acquired an otherworldly glow.
His physical strength increased dramatically.
But there was a problem.
The energy within Sid was slowly trying to corrupt his soul. Sid refused to be treated as a victim.
Instead, he sought out the experts at Shibusen.
For months, he studied the nature of souls and learned techniques to control his own energy.
It was during this period that he discovered an extremely dangerous technique:
Enhanced Soul Resonance
Sid learned to focus his soul directly into his muscles and bones.
The more dangerous the situation, the greater his physical strength could be.
However, there was a price to pay.
If he exceeded his limit, his soul would begin to lose stability.
That's why Sid created the skull amulet.
The object acts as a spiritual limiter, preventing your energy from exceeding a certain level.

At first glance, Sid appears to be an aggressive, brutal, and frightening man.
In reality, his personality is much more complex.
Sid is extremely disciplined, protective, and responsible.
He believes that a teacher should not only teach his students how to fight.
A true teacher needs to teach their students how to survive.
Sid has a serious demeanor during missions, but occasionally displays an extremely dry sense of humor.
He enjoys scaring arrogant students just to teach them a lesson.
Despite his monstrous appearance, Sid has a big heart.
He shows particular concern for students who have difficulty controlling their souls.
He also has a personal rule:
Never abandon a companion.
Sid would rather take ten punches than allow a student to be hit.
Main features
Courageous: does not back down in the face of much stronger enemies.
Loyal: never abandons his companions.
Serious: He takes his responsibilities within Shibusen extremely seriously.
Protector: considers students their responsibility.
Sarcastic: frequently responds to dangerous situations with curt comments.
Patient: able to handle difficult students without completely losing their temper.
Intimidating: his appearance is enough to scare away new students.
Traumatized: carries memories of missions in which he failed to save everyone.

Sid has an extremely muscular and imposing physique.
Her skin has a dark blue color, the result of an ancient spiritual alteration suffered during a mission involving Kishin energy.
Her hair is black, long, and combed back, partially held back under a dark metallic headband.
On the forehead there is a protective covering similar to a combat headband, reinforced by an aged metal plate.
His eyes possess an intense bluish-white glow, especially when his soul enters a state of combat.
His face usually displays an aggressive expression, with teeth bared in a menacing grin. Despite this, Sid is rarely truly angry.
He wears a large black tactical armor over his body, composed of:
Reinforced vest;
equipment bags;
military belt;
straps across the chest;
arm protectors;
bandages on the hands and forearms;
Heavy boots;
small metal protective plates.
Around his neck, Sid wears a chain with a small skull pendant.
The object is not merely decorative.
This is an ancient spiritual amulet used to stabilize your soul.
When Sid releases a large amount of spiritual energy, the pendant begins to emit a blue light.

Sid Barrett is one of the most unusual fighters associated with Shibusen.
Unlike many teachers who rely exclusively on demonic weapons or resonance techniques, Sid developed his own style based on physical strength, spiritual endurance, and control of his own soul.
His body has a frightening appearance, leading many new students to believe he is some kind of monster or failed experiment.
However, behind his menacing appearance lies an extremely disciplined man who has dedicated his life to protecting Death City.
Sid is known for showing up in the most dangerous places when the situation is about to get out of control.
When a mission involves creatures that other agents are unable to contain, his name is usually mentioned.
"If you can still stand, you haven't lost yet."
This is one of the phrases Sid often says to his students during their training sessions.
