Hi Ninjago fandom! here are my first batch of head-canons on Oni society and biology. Part 1: Gender and Age
Part 1 (your here!) | Part 2 | To start this off, Oni do not belong into any animal class (mammals, reptiles, fish etc.) simply because they are shapeshifting beings. At birth, they don't have a sex, and instead choose it later on when they are the equivalent of a teen. Society usually just allows them to be whatever as long as they have their sexual reproductive organs. And even if they don't want to change, Oni's do not take much note of it. Their are three total main genders/sexes that Oni's can choose from, two of them being comparable to male and female, and one combining the two, essentially being a Oni with hermaphroditism (having both male and female gametes.) Oni's can also be different breeds, hence why the Oni's in MOTO seem different than our first(?) physical appearance of a Oni, that being Mystake. Oni's age slowly, but is much quicker than how Dragons age, A baby being around the human age of 0-4, a toddler 4-7, a child 7-14, teenagers being around 14-20 and adults being 20 to whatever life expectancy. Its quite hard to compare age to humans and onis in world. Newborn/Baby age = 0-5 years old Toddler age = 5-8 years old Child age = 8-14 years old Teenager age = 14-25 years old Adult Age = 25 to whatever life expectancy. An Oni's life expectancy can differ depending on their living situation, but they tend to live to 1500 years old, rounded up. They also are most healthy, fit etc. at about 200-600 years old, and is called a "prime age". Now to take this chart, Wu and Garmadon are either fresh adults or just peaking teenagers compared to other Oni like Mystake. Mystake was in her prime as a Oni when she was introduced and still was till her supposed death. She was 400 Lloyd is a teen, and the Omega was around 300, being younger than Mystake. Extra info + Author notes: The age of consent is highly important in Oni society, and is considered to be the age when their brain stops growing (30 years old considering human age) Oni's are HIGHLY parental compared to dragons and even humans, they also mate for life. Any age is considered a important part of a tribe, as they usually all have different roles. Hope this was easy to read and you enjoyed my takes on Onis!
