About the four original Ninja and their lives

"Ha, that's not all that I'm master of! I do a little inventing; I dabble in model building, a touch of cooking, a little poetry..."

―Jay

Jared Calvin Aaron Walker is a lightning-fast 20 year old (but rather immature) inventor/electronic/ninja-of-lightning. He has a humongo crush on Kai's sister Nya His career as a ninja, well, he doesn't really take all that super seriously, but the other two jobs are simply for the extra money. His biggest fear is spiders. No matter how big or small, he manages to scare everyone to death with his bloody murder screams. His family is humongous. It will get even larger when his three brothers and sister get married and have kids. He has four uncles, Jack, Bob, Zane (yes, the ninja Zane) and Rex. Jack is an astronaut and is brothers with Bob. Bob is a police and trains Jay's twin brother Tom.P (A.K.A Tompy) as a police as well. Rex is a power miner and is brothers with Zane and Jay's Dad, Ed. Ed is a construction worker with the meanest boss you could imagine. And Zane, well, you know what he does for a living.
Jay's twin brother Tompy is his alter ego when it comes to personality; Jay starts laughing hysterically at his own jokes when Tompy has no way whatsoever of telling a joke apart from normal talk. His other brothers, P.T. and P.C., are a different matter. They are the silliest twin 12 year olds on the planet. The only notable difference is there pants or ninja suits. Zane's girlfriend and Cole's sister. Nicky is Cole's girlfriend but Jay likes her too. He gets away with it by saying she's his sister; it gets very confusing. Ed's dad, Zane's godfather and Rex's father is the famous Irish Detective Daniel Cruse. Ed always had liked the name Walker than Cruse, so he took his wife's last name instead.
Also, their Mom, Edna's, dad is "Brains" the power miner. P.C. and P.T. are identical Copies of each other accept for their smiles. The same is with Tompy and Jay, but instead of their smiles being different, it's their hair color; Jay's is red and Tompy's is brown like his two younger brothers.
Jay's quick wit and happy outlook on life helps him tremendously to help the team of ninjas get out of trouble. But Jay also speaks his mind; often without thinking first. As well as speaking his mind, he tends to think a bit too highly of himself; especially when he beats every ones high score on anything, he is obsessed with them. His small build makes him seem as if he were light as a feather; in this he takes no pride. You could say he's jerk, but he can't help himself. You shouldn't blame him; his brothers drive him to this annoying energy. His dog Nixon tries to help Jay keep his little brothers under control but, "those stinkers are too fast!"

"I'm on fire. I'm a fiery, fierce, friendly fiend."

―Kai ZX

"Why should my brother have all the fun? You're toast!"

―Nya

Kai grew up as a blacksmiths apprentice in a small village with his sister, Nya. His hot temper and loner type fighting skills get him into quite a bit of trouble; but Nya always helps him out. He loves his sister very dearly and will do anything to protect her (even though she really needs to protect him). Nya later reveals herself as the mystery man: Samurai X. Kai's passion to help and protect he started after his mother and father died some years ago. An interesting connection between Sensei Wu and their father is that when lord Garmadon fell and wanted the four weapons of Spinjitzu, Sensei asked Kai's father to hide the map to where he had hidden the weapons in his shop. Kai and Nya never knew this until Sensei Wu told them after they had recovered the weapons. He also has a big crush on Cole’s sister Jessie, Jay's sister Nicky and Zane's sister Shalom. Kai gets very angry when Jay flirts with Nya.

"I give you the chills? I don't quite follow."

―Kendo Zane

Zane is not actually a real human; he is (as Jay dubbed him) a Nindriod. His real father had just recently told him that he was actually a robot made to protect those who can't protect themselves. His sister Shalom followed after her brother and became a ninja as well, the Ninja of Frost. Zane tried to tell small jokes after he found out he was a robot; he still has feelings. Now he is obsessed with trying to fit in with the rest of the ninja.

"Nice to meet you kid, I got your back. And for the record, there ain't nothin' in this world that I'm afraid of."

―Cole

Cole is a rock solid member of the team and has many encouraging words to support them. He used to have dragonaphobia, but after getting to know his dragon, more, has come to have a closer relationship with Rocky. Now with the snakes gone, (which if he doesn't like anything, its snakes) he is free of the Serpentine forever. His real father, Jim, raised him on a ranch 60 miles north of Santa Fe New Mexico with his brother Ryan, and sisters Jessie, and Summer Melody. When he found out that Zane wanted to marry his (his sister his that his adopted dad had) sister, Mandy, but eventually got over the idea of it.
