Ninjago Head Canons

Ages

I obviously don't know their real ages but like everyone, I have some guesses, plus it doesn't help that time does pass in their world but I cannot tell you how fast, which means I don't know how long they've been their ages xD

Cole: 18
I feel like if he was any younger with those abs of his he would look too weird, even with his super strength he built those muscles up himself and I believe that 18 is a believable age to achieve that physique.

Kai: 16
Kai to me really seems to fit the age of 16. He has more majority to him because of taking care of himself and Nya but he's also still a young teen trying to figure life out. He carries himself as someone who's been a teen awhile so he doesn't act like a new teen but is young enough that he isn't fully concerned with the early stages of adulthood just yet.

Jay: 15
I believe our ninja of lightening sits just right behind Kai at the age of 15, though he's born early in the year so he's pretty close in age with Kai only being younger by a few months

Nya: 15
Nya is also in my mind 15, she is still like a new teen in some ways but she's mature for her age and is really smart and clever. She just fully possesses the style of someone who is ignored at times for being young even though at times she knows more than those who are older. Though unlike Jay I say she's born later on within the year making Jay older than her by a couple of months

Zane: 68 or 17
Depending on how old he looks or how old he actually is I believe he's like 68 because Dr Julian was young when he made Zane then he died came back alive and died again so Zane is getting up there in age himself but he is a Nindroid so he was built to look a specific age which in my mind is 17.

Lloyd: 12 or 16
I believe that he is 12 his actual age but simply because of the aging tea he looks to be 16 right behind Kai. Also, just the thought that Lloyd looks older than Jay even though he is technically younger is hilarious to me, cause I can totally picture the ninja teasing Jay about being the youngest when he technically isn't.

Here are my age Headcanons, I've returned for a lil update as some ages were confirmed or talked about being different than what I thought, but I still stand by this Headcanon personally so I haven't changed it.
