P.i.x.a.l

P.I.X.A.L.^[1] (Primary Interactive eX-ternal Assistant Life-form), alternatively spelled Pixal^[2][3] and known as Pix to her friends, is a female android created by Cyrus Borg to serve as his assistant. During the Nindroid crisis, she was briefly under the control of the Digital Overlord and turned on her friends but soon became a vital ally to the ninja after being redeemed by Zane. She and Zane formed a close relationship until he sacrificed himself to destroy the Golden Master. P.I.X.A.L. found out he survived and set off to save him from a mysterious island. While there, she was captured by Chen's cultists, and her body was scrapped, though her consciousness lived on in Zane's processor after Zane placed her hard drive inside his head.

For some time, P.I.X.A.L. guided Zane as an A.I. program in his head. When Nadakhan arrived in Ninjago and tormented the ninja, he deceived Zane into letting him erase P.I.X.A.L.'s consciousness—though due to Jay's final wish, this was undone. Later, P.I.X.A.L. left Zane’s head and gained a physical body, similar to how Zane had done. She took on the alias of Samurai X, a role once played by Nya, so she could adopt a more physical role in the ninjas' missions. P.I.X.A.L. helped battle the Vermillion and later the Sons of Garmadon, and she helped Lloyd and Nya to resist Lord Garmadon's oppressive hold of Ninjago City.

Unfortunately, P.I.X.A.L. was captured along with the majority of the Resistance after an ambush by Garmadon's forces, but her actions allowed Lloyd and the others to continue in their endeavors. Eventually, she got word that the ninja returned and broke out while joining the others in toppling the Colossus with the heroes. Later on, the people of Ninjago threw a party to celebrate the end of Lord Garmadon's rule, as P.I.X.A.L. is honored for her role in saving the city as well.

When the Oni invade Ninjago, P.I.X.A.L. alone, in her Samurai X Mech goes into the darkness to rescue Lloyd and Garmadon after they acquire the Golden Armor. She later defends the civilians at the Monastery when the Oni arrive. She rescued Lloyd and Garmadon before helping her comrades to defeat the Oni.

Months later, Zane ends up banished to the Never-Realm by Aspheera, leaving her heartbroken, believing he was dead until told otherwise before assisting the ninja in transporting them to the Never-Realm while she stayed behind with Wu. During the wait, she arrests the Mechanic, Ultra Violet, and Fugi-Dove, who attempted to escape Kryptarium Prison. She also defeats a revived Preeminent after inadvertently releasing it from the Departed Realm. Days later, the ninja returned with Zane, and she immediately embraces her boyfriend.

While the ninja (excluding Zane) are in Prime Empire, she and Zane embark on a search to find Milton Dyer. They succeed, leading to the eventual release and revival of the trapped Ninjago City gamers, the game's NPCs, and the ninja.
