Kai Smith

Appearance: Typically preferring red attire, Kai has tall, thick spiky brown hair, shaped like fire. He is often seen with a focused expression on his face, with a scar visible on his right eyebrow and a bandage above his left, which has been there for a long time, possibly because he thinks it looks cool.

Personality: Fittingly for his elemental affinity, Kai is very hot-headed, prone to taking action before he thinks things through. He is capable of making careful observations when the need arises, but his emotions often override his caution. His single-mindedness made interaction with his teammates difficult at first (especially due to his worry about Nya), but he eventually learned to work with the other ninja. He can be very cocky at times, especially earlier in his career as a ninja, sometimes even to the point of selfishness, insisting that he is better than others, gloating about his victory, or yelling about his failures. He seems to have a large ego as he wanted to be the Green Ninja and lead the team. He eventually grew out of this for the most part, though he occasionally lapses back into a similar mindset. But those emotions are also when his strength is greatest, especially when protecting those he cares about. Kai's personality represents caution, growth, safety, and warmth. He may not say it much, but he deeply cares about his loved ones and will do anything to protect them, even at the cost of his own life, which is why he's so overconfident. Kai also has something of an overconfident stubborn side, believing that he is in the right until overwhelming evidence to the contrary is presented. Overall, Kai is a tough, brave, confident, passionate ninja. The most prevalent facet of Kai's personality is his good heart and dedication to the people he cares about—if someone can earn his friendship, he will stop at nothing to protect them. Much of his stubbornness and recklessness is due to his desire to help his loved ones, either directly or by becoming strong enough to defeat anyone who might threaten them with their plans. In turn, his friends and family work to balance out Kai's more extreme traits, causing him to become a level-headed mentor for Lloyd by the time he and his comrades begin training the Green Ninja. According to Zane, Kai's desire to protect his friends is just as powerful as his temper.

Family and friends: Family: Ray (father) Maya (mother) Nya (younger sister, the water ninja) Appearance: Nya has long dark hair kept in a ponytail, with long bangs, pale pink lipstick, and small dimples on her cheeks. She has a beauty mark on her right cheek. Personality: Although she was not trained as a ninja early on, Nya is very capable of defending herself. She did not like the fact that so much focus is put on the ninja, so she resolved to become a hero in her own way, which she did by becoming Samurai X, and is highly independent, desiring the choice and ability to choose her own identity and destiny. She also gets annoyed when people look at her differently because she's a girl within a prominently male group. Allies: Skylor (crush) Ninja: Lloyd (green ninja) Appearance: Lloyd has mid-length, blond tousled hair, and brown arched eyebrows. His eyes are visibly green, and occasionally glow when he uses his powers. Personality: Lloyd is the wise leader of the team and is fully dedicated to the way of the ninja. Once a mischievous and easily distracted child trying to follow in his evil father's footsteps, after becoming the Green Ninja, he has since grown into a quiet and mature young man. He is deeply fond of his friends and family and will stop at nothing to defend them, even prioritizing their safety over his own. He is goodhearted and at times naïve, making him an easy target of deception by his enemies. Zane (Ice ninja) Appearance: Usually seen in white clothing, Zane's Titanium form has silver hair in a tall flat-top/crew cut hairstyle with no sideburns, and sharp eyebrows. He has glowing blue eyes which are optical sensors and is usually seen with straight-faced expression. Personality: Zane is undoubtedly the most serious and reserved of the ninja, as he had no sense of humor and didn't understand the way his fellow ninja socialize. He has little understanding of humor or even basic social conventions. Jay was teaching/informing Zane about humor. He also has a strong bond with Master Wu, being the most polite and respectful towards him and finding a sort of paternal presence in him; the two share moments of quiet while the other ninja goof off in a way he can't connect with, or when the ninja are with family and he has none. The other ninja are occasionally wary of his strange habits, but they quickly learn to accept him for it, even relying on it. Cole (earth ninja) Appearance: Cole has a muscular body He has medium length , shaggy black hair and bushy eyebrows. Personality: Cole used to be more uptight and strategic, disapproving of Kai's impulsiveness. Before meeting Wu, Cole lacked direction and purpose. At this time, his mother just passed away and he was struggling to take care of the family himself. As a ninja, Cole thoroughly enjoys helping others in need and feels accomplished with a job well done. Jay (lightning ninja) Appearance: Jay has curly hair generally wearing blue clothing to represent his elemental color. He has brown eyebrows and light freckles, he has reddish-brown. Personality: Jay is the most light-hearted and energetic of the ninja. He is always telling jokes, most of which are only funny to himself. He usually does this to cover up fear and anxiety, He is also sensitive in both positive and negative ways and thinking. He enjoys boasting about his abilities, such as inventing and poetry, much to the annoyance of the others, but he proves to be a good friend and a skilled fighter. He is also somewhat high-strung, typically being the first to panic in dire situations.
