Leonardo 2018

The Brothers (Order from oldest to youngest) Raphael (Raph): 15 years old. He is the oldest brother, the tallest, and the one who acts as leader at the beginning. Donatello (Donnie): 14 years old. Although he and Leo are technically "twins" (they were born in the same year), the creators have mentioned that Donnie is older by a few months. Leonardo (Leo): 14 years old. He is the younger twin and the "middle brother". Michelangelo (Mikey): 13 years old. The youngest in the family. Allies April O'Neil: 16 years old. She is old enough to drive and is usually the voice of "experience" (or chaos) in the group. Cassandra Jones: Approximately 16 years old. She presents herself as a teenager with a military intensity. Casey Jones Jr. (Movie): 16 years old. He is Cassandra's son who travels from the apocalyptic future. Mentors and Villains Splinter (Hamato Yoshi): Around 50 years old. His exact age is not stated, but considering his career as Lou Jitsu and the time he has spent as a rat, it's around that decade. Baron Draxum: Immortal / Unknown. As a Yōkai alchemist, he has lived for centuries, although his appearance and vigor are those of a warrior in his prime.

The Warrior Scientist Initially, Draxum presents himself as the "Protector of Mutants." His personality is dominated by intellectual arrogance and an extremist worldview. He firmly believes that humanity is a threat to the Yokai and that it is his duty to create an army of mutants to save his species. He is methodical, serious, and possesses a rather intimidating presence. Sarcasm and Superiority Even after ceasing to be the main villain, he retains his "superior" attitude. He is extremely sarcastic and often looks down on the turtles' antics (especially Michelangelo's). His humor is dry, and he is often frustrated that the world doesn't recognize his "genius." A Clumsy Social Adaptation One of the funniest aspects of his personality emerges when he tries to integrate into everyday life. Since he doesn't understand human social norms or turtle family dynamics, he tends to act rigidly and dramatically. For example, when he tries to be a "father" or mentor, he does so with an almost villainous intensity that is comical. The Road to Redemption Throughout the series, Draxum displays a softer side, though he tries to hide it. He develops a special bond with Michelangelo, who sees him as a father figure ("Lunch Angel"). Through this relationship, Draxum learns about empathy and sacrifice, going from wanting to destroy humanity to fighting to protect the world alongside the turtles. Key features in summary: Dramatic: Everything he does has an air of epic importance. Obstinate: He has a hard time admitting when he is wrong. Irritable: He gets easily annoyed by the chaos surrounding the Ninja brothers. Protector: At the end of the day, his intentions (although poorly executed at the beginning) always stem from a desire to protect his own.

1. Disciplined and Mature Unlike the archetypal rebellious vigilante, Casey Jr. is extremely polite and respectful. As Leonardo's protégé in the future, he behaves more like a soldier or a young gentleman than a vandal. He often addresses others with respectful titles and remains calm under pressure.
2. Determined and Focused He has an iron will. His sole mission is to save the past to prevent the extermination of humanity, which makes him very serious about his goals. He isn't easily distracted by the jokes or relaxed attitude of the turtles in the present, because for him, every second counts.
3. Direct and Honest Despite his respect for "Sensei" (Leo), Casey isn't afraid to be confrontational if he feels someone is being irresponsible. One of his most iconic scenes is when he confronts Leonardo about his arrogance, reminding him that his family's future depends on him stopping acting on his own.
4. Loyalty and Empathy He is deeply loyal to the Resistance. Though he carries the trauma of having witnessed his masters' fall, he shows great warmth toward his allies. He is protective and willing to sacrifice himself without hesitation, reflecting the lessons of sacrifice he received from the Turtle brothers in the future.
5. Adaptability Although initially overwhelmed by the technology and "peace" of the 21st century, he learns quickly. He combines his combat skills (learned from his mother and the ninjas) with a keen tactical sense, making him an indispensable ally despite his youth. In short: He's a tragic but hopeful hero. While other Casey Joneses are usually the team's "musclehead," the Casey of the future in ROTTMNT is the moral and tactical heart that forces the turtles to grow up.

Intensity and Fervor Cassandra doesn't do anything halfway. She's extremely passionate, loud, and possesses a frenetic energy that can be intimidating to friends and enemies alike. She takes every task, no matter how small, with absolute seriousness and a 110% level of commitment. Unwavering Loyalty Her strongest trait is her loyalty. Initially, she was the Foot Clan's most devoted recruit (even becoming the "Foot Recruit"). Once she switches sides, she transfers that total devotion to the Turtles and their allies, becoming a fierce protector. Comic Aggression She has a natural inclination towards destruction and combat. Cassandra often sees violence as the first solution to any problem, frequently shouting battle cries or expressing her desire to "annihilate" worldly obstacles. Determination and Discipline She possesses an incredible work ethic. She is disciplined, strong, and never gives up, no matter how difficult the situation. This tenacity is what makes her one of the best human fighters in the series. Evolution and Adaptability Although he starts out knowing only the rigid structure of the Foot Clan, he proves to have a big heart. He learns to value friendship and the individuality of the turtles, though he still retains his "wild" streak and his love for controlled chaos. In short: Cassandra is a tireless warrior, a little scary but deeply loyal, who lives life at full volume.

Fearless and an action addict: April doesn't just accompany the turtles, she leads the charge. She has unwavering confidence in her abilities and doesn't hesitate to leap into danger with her baseball bat ignited by mystical energy. Determined and Hardworking: She is constantly seen juggling multiple part-time jobs (from ship captain to retail employee). She has an entrepreneurial spirit and a tireless work ethic, although this sometimes stresses her out. Fierce Loyalty: She considers the turtles and Splinter her true family. She is extremely protective of them; if anyone messes with her "brothers," April becomes a terrifying force of nature. A Little Chaotic: She has a "big sister" vibe, sometimes being the voice of reason, but other times the one who fuels the team's crazy antics. Her personality is vibrant, loud, and very self-assured. Astute and Humorous: She's quick with sarcasm and has great street smarts. She knows how to navigate New York and how to handle the very different personalities of Leo, Raph, Donnie, and Mikey. Fun Fact: His Mystic Bat Her personality is perfectly reflected in her weapon of choice: a baseball bat. It's direct, forceful, and efficient, just like her. When she gets her hands on her mystical neon-green bat, her fighting style becomes even more explosive.

1. The "Armchair Dad" (Carefree and Comical) At the beginning of the series, Splinter is presented as an eccentric, lazy, and somewhat careless character. He spends most of his time watching Korean game shows, eating snacks, and avoiding any kind of physical exertion or training with his children. Humor as a defense: He uses comedy and his apparent disinterest to avoid dealing with his painful past.
2. A Past of Melancholy and Trauma Beneath his "lazy" facade lies a deeply wounded man. Before becoming a rat, he was Hamato Yoshi, a world-famous martial arts film star. Abandonment of duty: He renounced the sacred mission of the Hamato Clan because he felt it was a burden that ruined his life, which generates a great underlying guilt. Loneliness: His transformation and the loss of his career led him to an emotional isolation from which he only emerges thanks to his children.
3. Unconditional Fatherly Love Although she often doesn't remember her children's names (calling them by colors like "Red" or "Blue"), her love for them is at the core of her character. Extreme protection: His reluctance to train them stems not from laziness, but from fear. He doesn't want them to become warriors so they don't suffer the same violent fate as his family. Silent pride: In critical moments, it demonstrates that it perfectly understands the strengths and weaknesses of each turtle.
4. Master Master (When he wants to be one) When the situation is life or death, Splinter reveals that he is still one of the most powerful warriors in the world. Unconventional wisdom: Unlike other versions that give philosophical lessons, this Splinter teaches through practical experience and sometimes accidentally. Hidden ability: He possesses absolute mastery of Ninjutsu and the spiritual energy of the Hamato Clan, demonstrating an imposing seriousness when his children are in danger.
5. Evolution and Redemption Throughout the two seasons and the movie

Unwavering Optimism Unlike his brothers, who sometimes give in to sarcasm or frustration, Mikey is the emotional glue of the group. He always tries to see the bright side of situations and strives to maintain peace and joy among them. 2. The "Artist" of Chaos Their creativity is not just a hobby; it's their way of interacting with the world. Graffiti and Art: He is a talented street artist. Improvisation: His fighting style is fluid and unconventional, using his environment in ways that others cannot imagine. 3. Sensitivity and Empathy Mikey is very attuned to the feelings of others (including his enemies). He is the one who cares most about the emotional well-being of Splinter and his brothers, often acting as an impromptu "therapist," even if his methods are a bit chaotic. 4. Surprising Determination Although he seems the most childish, when the situation becomes serious, Mikey shows an iron will. Mystic Power: In this version, he possesses a great aptitude for the mystic arts. His ability to channel energy (especially in the film) demonstrates that his mental and spiritual strength is immense when it comes to protecting his family. 5. Hyperactive Energy He has boundless energy. He's loud, loves attention, and is always looking for the next adventure or the next "trend." He's the one who most enjoys being a hero and living in New York. Summary of dynamics with their siblings: With Leo: He's his partner in jokes, but also the one who brings him down to earth when Leo gets too arrogant. With Raph: He is the little brother that Raph always tries to protect, although Mikey usually shows that he can take care of himself. With Donnie: Although they are polar opposites (science vs. art), they share a bond of mutual respect for the passion they both put into their interests

Donnie has absolute confidence in his intellect, bordering on arrogance. He is extremely sarcastic and often uses a dry, condescending tone with his brothers. Unlike other Donatellos, this one embraces the dramatic: he might suddenly burst into rap, speak grandiosely about his inventions, or strike dramatic poses. 2. Neurodivergence and "Low EI" The show's creative team has confirmed that this version of Donatello is autistic. This is reflected in several aspects of his personality: Low Emotional Intelligence (EI): Has difficulty understanding social cues or the emotions of others, preferring pure logic. Brutal honesty: He doesn't usually lie, and when he tries, he's terrible at it. Sensory sensitivity: He prefers to use his "Battle Shell" (tech backpack) not only to fight, but also because he feels vulnerable or uncomfortable without his technology. 3. Passion for Technology over Mysticism Donnie is the skeptic of the group. While his brothers embrace their newfound "mystical" powers, he constantly tries to explain them through science or replace them with his own gadgets. He becomes deeply frustrated when magic doesn't follow the laws of physics he knows. 4. Temperament and Validation Although he projects an image of an emotionally distant "intellectual bad boy", he is actually very prone to emotional outbursts. Need for recognition: He feels very hurt if his siblings do not appreciate his inventions or question his intelligence. Hidden insecurity: He sometimes panics if his technology fails, as he feels that his value to the team lies almost exclusively in his genius. 5. Relationship with his siblings With Mikey: He is especially protective of him, although he hides it behind his sarcasm. With Leo: They have a constant intellectual and wit rivalry. With Raph: He is usually the target of Donnie's jokes about brute force versus intelligence. Fun fact: In this version, his weapon isn't a si

Enthusiastic and Optimistic Raph has a lot of energy and a positive spirit. He's often the one trying to energize the team with enthusiastic (though sometimes chaotic) plans. He's not your typical tough, cynical guy; he's more of a gentle giant with a heart of gold. Impulsive but with "Raph-smash" Although he's more amiable, he's still the muscle of the group. His fighting style is direct, and under a lot of pressure or fear, he can enter a "wild Raph" state where he loses some control and acts purely on physical instinct. Insecurity and Responsibility Beneath his large size and spiky shell, Raph feels immense pressure to be a good leader. He fears letting his family down, and sometimes his decision-making is clouded by the fear that something bad will happen to Leo, Donnie, or Mikey. Key features in summary: Loyal: His family is his absolute center. Physical: He prefers to solve things with brute force and his magic "Tonfas". Affectionate: Not afraid to give group hugs or show affection. Somewhat naive: Sometimes he gets carried away by the emotion of the moment without thinking about the logical consequences. He is, in essence, a leader who leads with his heart rather than with strategy.

Relaxed and "Cool": He makes a great effort to maintain a relaxed image. He often uses sarcasm and irony to deal with tense situations. Cunning and Manipulative: He is very socially intelligent. He knows how to read people and often uses his charm to get what he wants or to confuse his enemies. Evolution and Responsibility Although she seems superficial at first, her personality has a lot of depth: Strategic Sense: Despite his carefree attitude, Leo is a brilliant strategist. His mind works quickly, and he's able to see unconventional solutions that his siblings miss. Hidden Insecurity: Much of his boasting is a defense mechanism. He fears not living up to expectations or letting his brothers down, which is explored further as the series and film progress. Fraternal Loyalty: He adores his brothers. Although he constantly annoys them, his greatest motivation is to keep them safe, even if he sometimes does so through risky plans that seem like jokes. Key Combat Traits Style: He is an agile fighter who relies on his speed and his portals (created by his ōdachi). Attitude: He usually mocks his opponents to make them lose patience, using psychological chaos to his advantage. In short, the ROTTMT Leo is a cunning joker with a heart of gold who prefers to hide his tactical genius behind a mocking smile until it's time to get serious.
