Zane and P.I.X.A.L

P.I.X.A.L. was originally shown to be quite emotionless and impassive and had only her duties to Cyrus Borg as her primary concern. Things like duty, honor, and compassion at first meant nothing to her, but throughout her adventures with the Ninja, and her interactions with Zane, she developed immensely as a person. P.I.X.A.L. originally had no interest in others besides a basic curiosity and desire to learn, but after meeting with Zane, her behavior changed. When she was pondering on helping the ninja to shut off power, she quickly ignored any doubts or reasons in it to save. When she was shut down and given part of Zane's power, she slowly became more human and her emotions soon surfaced, showing that she was capable of exemplary bravery, compassion, humor, and friendship.

Her most human traits were shown primarily around Zane, an android like her, who taught her to embrace her hidden humanity and subsequently know things like deep love, civic duty, friendship, but also loss and heartache. This was shown as she was deeply shocked after Zane's apparent death and sacrificing of his original body to defeat the Overlord; she had been affected more than anyone by his death to the point where she avoided his memorial in her inability to accept his passing but was overjoyed by discovering his resurrection. She also developed a deep faith in Zane and his strength of character, showing a profound level of emotional intimacy and devotion to her love. Although she is a good fighter, she prefers peaceful ways to end the fighting, as she asked the Preeminent and the octopus to stop their activities, rather than being forced to defeat them by force.

After adopting the Samurai X persona, P.I.X.A.L. hid the fact that she had a new body and was protecting people to have her own identity. As she told Zane, she would have preferred to have her own body and not be part of the computer, but she asked him if he agreed, as she really wanted to be a useful member of the team. Following her reunion with Zane, she was very happy and they embraced in their reunion.

As of late, P.I.X.A.L. shows a snarky side thanks to her spending too much time with Zane and how he is starting to get on her nerves with his habit of emulating characters from data that he found online.

When he was introduced, 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 (as seen when he walked into the bathroom, despite Cole being on the toilet). It's inferred from the pilot episodes that 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, like with the robotic Falcon in Season 1, leading them to find all sorts of things, including Zane's past.

Initially, Zane was melancholy over his inability to remember his parentage or where he came from. He eventually accepted the ninja as his family and that their home was his home, but he never truly gave up on finding details of his past. Upon learning his origins, he was briefly struck by shock and depression, only to overcome his feelings and accept his robotic nature when he restored his memories, causing him to unlock his True Potential. When he eventually reunited with his father/creator, Dr. Julien, in Season 2, he readily accepted him as his father figure.

Zane is quick to form strong attachments, the most attached to the idea of his fellow ninja as his "brothers" and finding a deep kinship with the Falcon and companionship with P.I.X.A.L. minutes after meeting them. He has been known to take heavy risks on impulse for the people he loves, even if, in the case of P.I.X.A.L., there is no evidence he should trust them yet. On many matters, Zane's unusualness and people's tendency to ridicule him are a result of his tendency to care deeply in a way others wouldn't—a food fight and a mockery of his pink apron drove him to run off, meeting a fellow android had him falling for her hard and refusing, even before he knew her, to reconcile with her being evil or to leave her behind as an enemy. Zane is often inclined to speak more honestly about emotions that others would tend to mask, like grief or confusion.

After rebuilding himself as the Titanium Ninja, Zane has become even more accepting of his own robotic traits. He considers himself in some ways a new person—which allowed him to unlock his Elemental Dragon. After this change, Zane is more willing to joke at others' expense, cockier, and his sense of humor has been known to be bitingly sarcastic, though his core values and programming remain intact. However, since the beginning he has struggled to understand figures of speech, relying on his friends to explain every so often. Sometimes, he will still interpret the phrases incorrectly.

Zane is a very intelligent Nindroid, with a vast array of knowledge at his disposal, a gift for cooking, and a knack for statistics. It can be inferred from the Season 8 and the Tales from the Monastery of Spinjitzu that Zane continues to upgrade parts of himself. His companion P.I.X.A.L. was a part of his artificial intelligence from Seasons 4 to 7, in which he had her company everywhere he goes. However, he ended up being too dependent on her for analysis. His pattern of speech also displays his intelligence. He is formal and has a larger vocabulary than the others.

Zane learns more quickly than the other ninja, as shown to be the first to find his True Potential and tapping into Lloyd's Golden Power in the Digiverse, getting the only compliment from Cole's father on his dancing, and learning to use the chain gun easily in the Realm of Oni and Dragons. It is also shown in Season 1 and 2 that he has the most endurance and can breathe underwater and in space, which makes sense for a robot.

Being stranded in the Never-Realm caused Zane to become despondent, as he had no way to escape and was alone. During his message in the Titan Mech, he identifies himself as Dr. Julien's son, voiced his happiness in his time with his friends who he saw as family. He also voiced his love for his robotic companion P.I.X.A.L., should he not return to Ninjago.

His values comes from the phrase, "You were built to protect those who cannot protect themselves," which was first stated by Dr. Julien. He has stayed true to this in a variety of situations, like against the Digital Overlord, and on Chen's Island. He is also typically very supportive of his friends. It was this phrase that allowed him to regain his memories after he became the Ice Emperor.

He is also very modest, expressing reluctance to have attention called to himself of multiple occasions. In "The Last Hope," he is the most modestly dressed, wearing a button up shirt and khakis while the rest of the ninja wear swimsuits, Kai and Cole without shirts. He continues this trend in the episode "Wasted True Potential," where, while in the hot tub, he wears a full body wetsuit; the rest of the male ninja simply wear swim trunks, with the exception of Jay who adds a tank top. Also in the Decoded episode "Legendary Places" when Jay mentions Zane's statue that was erected after his sacrifice, Zane states: "I… did not need a statue."

Due to his nature as a Nindroid, Zane can be insensitive to other people's feelings and often resulted into unwanted situations. Best shown when he turned off his mood switch so he won't experience the feelings of grief which offended Sally when he asks blunt questions about her and her parents. Another one of the recent examples is when he called Arin their "former ally" and how the Ninja wasn't searching for him but the Prismatic Blade which upsets Lloyd.
