Jay

The blue Ninja and Master of Lightning, Jay was raised in a junkyard with his parents, Ed and Edna, whom he eventually abandoned and journeyed to Ninjago City to test his inventions, which ultimately failed. However, Sensei Wu saw the Lightning within him and trained him with Cole and Zane at the Monastery, eventually meeting Kai and joining forces to find the Golden Weapons of Spinjitzu. Being the fastest of the ninja, he learns Spinjitzu at the Caves of Despair, and helps the others learn it as well.After foiling Garmadon's plans, he obtains the Nunchucks of Lightning, the Lightning Dragon, Wisp, both of which he keeps thereafter. His parents later revisit in the second season, who are held captive at the junkyard by the Fangpyre tribe and saved by their son. Jay appears to be the joker of the group, often annoying others with his constant talking and wisecrack jokes. Apparently, he has a crush on Kai's sister, Nya, who seems to know of his feelings about her.
