TMNT 2003-Mina

Raphael's hostility can sometimes cause tension, especially with Michelangelo and sometimes Leonardo. Raphael constantly gets frustrated with Mina's constant taunting and teasing, causing them to clash frequently. Raphael and Leonardo usually somewhat get along, but when they argue, it can get very tense as both of them can have very strong opinions, as it especially was shown in City at War arc. Raphael's biggest fear is to lose himself to rage becoming no different than the Shredder.

Raphael is intensely loyal and is often the first to react when any of his friends or family are in danger. A more caring and concerned part of his personality shines through when one of them is harmed or in serious trouble. In the episode "Tales of Leo", he even cries when speaking to a heavily injured and comatose Leonardo. In the following episode, "The Monster Hunter", Raphael forgoes all the action in the episode in favor of caring for Leonardo and helping him forge new katanas.

Raphael is a typical brash, street smart, no-nonsense, and headstrong New Yorker with a Brooklyn accent. His personality can be best summed up by the theme song from season 4 onward in which it's stated that you can always "count on Raphael to throw the first punch". His personality is similar to that of his original Mirage counterpart—he is aggressive and headstrong. However, he is slightly more sarcastic and moody. Despite being impulsive, he has better control over his anger. When it's too much though, he is still prone to bursts blind rage.

Throughout the series, Raphael is shown to struggle with his temper even though he is shown to be aware of the impact of it. Raphael has the hardest time with trusting enemies in situations due to fear they will harm him and his family let alone again. Raphael's deep love for his family, outweighs his anger.

Raphael Splinterson.He is the strongest of the team who uses his twin sai, other weapons, mastery of Ninjutsu to protect New York City from threats such as the Shredder. On top of being the strongest, he is the most temperamental and hostile, but his deep love for his family is what has him fighting the hardest.

Raphael is represented by the color red, most prominently reflected by his red traditional bandana. His skin tone is a deep emerald green, the darkest of the Turtles. He wears the same brown knee/shoulder pads and belt as his brothers. His weapon of choice is twin sai, which he carries in his belt.

For the last two seasons of the show, due to the differing animation styles in Fast Forward and Back to the Sewer, Raphael suddenly appears taller than his brothers with a slightly lightened skin tone.

Of the brothers, he has the closest bond with Splinter, often going to him for help and attempting to follow his orders to a T (at least when his brothers aren't out causing trouble, forcing him to go along with their antics). While responsible, Leo can still be sucked into trouble by his brothers out of his own curiosity or his sense of duty to keep an eye on them. All three of Leonardo's brothers view him as a pillar of strength. They are at a loss when he is injured or absent, such as in the first season when the Foot Clan beat him unconscious and put him near death.

Leo has a strong sense of honor and ethics, along with being a dedicated follower of the Bushidō code. Episodes that deal with the Shredder and honor usually also focus on Leonardo. Leonardo is the turtle who decapitates the Shredder early on in the series—of course, before they are aware that Shredder is in fact an evil Utrom by the name of Ch'rell who doesn't have a neck, let alone a distinct head. One of Leonardo's most prominent qualities is his determination to believe the best in people, even potential enemies. This trait can cross over with being naïve, though, as his trust almost led him to siding with the Shredder the first time they met. Even so, he is willing to give even people who betray him a second chance if he sees good in them, such as with Karai.

Even if he’s the most serious of his brothers, he’s still a teenager. He does know how to have fun, and he very much likes to play around every once in a while, like when he mocks Mina for her superhero drawings, calling it “The Legion of Sewer-Heroes.”

Leonardo is the leader, whose key attributes consist of honor, sensitivity, patience, and encouragement. He is the most "spiritual" of the four brothers. Despite being a teenager, he acts kind of like a grown-up due to all his seriousness, but can still have fun with his brothers.

He is the most mature and responsible of the four brothers, and takes honor and responsibility as his priority.

Leonardo appears to be a normal, healthy teenage mutant turtle. He is muscular and stocky like his brothers. His skin tone is forest green and he wears a blue ninja bandana. As of the season 3 finale, part of his shell by his left shoulder was broken off during the final fight with the Shredder, after Karai stabbed him in the shoulder. But as of season 6, it's been repaired.

Leo may be mature, but he sometimes would have a hot temper. He also can have emotional outbursts of rage similar to how Raphael would if he was upset, except more violent. The first half of the fourth season shows a more traumatized, dark Leonardo, due to his feelings of failure, as did a short period in season one after the Shredder returns, in which he became depressed and angry. It wasn’t until he accidentally injured Splinter and subsequently received training from the Ancient One that his personality returned to his normal level headed self.

Donatello will defend his brothers at any cost, and he frequently assists the team in many ways through the technology he develops, mostly vehicles and communication devices. He also can use ninjitsu and his Bo Staff when necessary. Donatello is very prepared for situations especially with his gadgets. For instance during the Turtles' infiltration of the Shredder's tower, where Don carried all the equipment and gadgets they would need in his duffel bag.

However, Donatello is still a teenager. He can be playful and mischievous like Mina, like when he and Raphael toss around Mina’s sketchbook and laugh at it.

Donatello is the calmest, peaceful and most pacifistic out of all his brothers. He's gentle, very peaceful, and doesn't really lose his temper. Sometimes he can be witty which rarely bothers his brothers, but overall, he is a gentle turtle who is well liked by all of his brothers never engaging in major confrontations with them. He is the turtle who brings peace with his brothers, as he was the one to reunite

He is the smartest and most technologically-adept Turtle. His personality is still the traditional technology Turtle, but unlike most other incarnations, he is the most passive and is rarely aggressive. His trademark bō is his primary weapon, but he has used other weapons such as laser guns and those of his brothers and sister

Donatello is a mutant turtle with olive green skin who wears a purple bandana and brown paddings on his knees, elbows and wrists.

Splinter is a very honorable person and is therefore disgusted by dishonor and cowardice. He is capable of fighting on par with the Shredder and also shows a great deal of cunning and resourcefulness in combat, such as when he tricked the Shredder into bringing a water tower down on himself. Despite his age, Splinter also shows amazing speed, strength and skill in combat. His simple walking stick is his signature weapon as he believes that in the hands of a true ninjutsu master, any weapon could be deadly.

In addition, instead of a traditional Japanese weapon, he carries a staff that he can use as a weapon (like a Jo staff) with fierce dexterity. This staff had several designs in the Lost Episodes it was a staff with a gold ornament around it and in Fast Forward it was a futuristic metal staff that combined with a wood part in the middle.

Splinter is a composed and loving father, raising the Turtles as his own sons and daughter but not hesitating to scold them when necessary. Despite having spent his life initially as a normal rat, and then living underground as a mutant, he is very wise and insightful. Regularly, Splinter has prove himself able to anticipate how his sons will react and likewise able to read the flow of battle to properly counter his opponent. At the same time, experienced as he is, Splinter has great difficulty using mechanical equipment, being unsure of how to answer a Shell Cell or control the Battle Shell remotely.

Splinter does his best to look out for them and would gladly give his life to protect them. In an alternate future where the Shredder takes over the world, that is exactly what he did. This overprotective streak made him reluctant to allow them to enter the Battle Nexus (dimension) competition; in fact he never even told his sons about it and they only found out because they followed him. However, Splinter also shows great faith in his sons, believing them to be fully capable ninja and even showing enough confidence in their abilities to allow them to face the deadly Shredder on multiple occasions, although during the majority of their encounters, he is there to support and protect them in any way that he can.

Hamato Splinter is the adoptive father and ninjutsu sensei of Leonardo, Raphael, Donatello, and Mina

Hamato Splinter is a mutant rat with white bushy eyebrows, black whiskers on his muzzle, a pink nose and tail, a nick in each ear, dark brown eyes, short fur, and a thin figure. He has four fingers on each hand and three toes on each foot and white claws. Unlike his other incarnations, this Splinter has gray fur instead of brown fur.

He also has a somewhat disheveled appearance, especially a small notch in each ear, this disheveled appearance can also be seen reflected in his clothing too, which consists of an a torn red-orange kimono with dark brown trim, as if to imply that he has gone through more hardship, or simply to match the tone of the series.
