Somehow, the three most original ninja (Cole, Jay, and Zane) all are (kinda) the same kind of thing as one of the villains. Jay is kinda a pirate with his eyepath and the statement Clancee made and season 6 has pirates, Zane and the season 3 villain army are all nindroids, and of course, Cole is a ghost, along with the season 5 villains. Watch out Kai...
