Lightning Dragon Battle is a Ninjago set that was released in Summer 2011. It includes Jay (DX), Sensei Wu(black robes), Frakjaw, and Kruncha with a green and purple spinner but without cards. It also contains a large blue dragon, and a Skeleton Helicopter. This set also includes 8 weapons: the Nunchucks of Lightning, a gold warrior sword, a silver flail, a black sword, 2 gold spears, and 2 long spears. When the ninja found the Nunchucks of Lightning, in the Floating Ruins, the Lightning Dragon (nicknamed Wisp by Jay) appeared. The ninja escaped the Floating Ruins but the dragon did not follow. When Kai and Nya escaped the Fire Temple, they brought the Lightning Dragon, along with the other Dragons, to the temple. Jay eventually rode the Dragon into the Underworld.
