Almost all of the ninja have a weird relationship with their parents.

The LEGO Ninjago theme has a recurring theme of parental relationships, with many of the ninja having complicated or absent connections with their parents. This unique aspect of the characters adds depth to the storyline.

Kai and Nya grew up without their parents, while Jay was abandoned but later adopted. Zane's memory of his father is lost, and he has no mother. Cole experienced the loss of his mother and initially struggled with his father. Lloyd's father was evil but loving, and he was abandoned by his mother. Arin's parents disappeared, and Sora wasn't accepted. Frak has an uncaring father, and Wyldfyre was abandoned, possibly for safety reasons, and adopted by dragons. Wu, Riyu, Rontu, and Egalt have no parents, and Morro is an orphan.

These complex family dynamics contribute to the Ninjago narrative, providing emotional depth and opportunities for character development. The various parental relationships shape the ninja's personalities and motivations throughout the series.
