Zane is the ninja of Ice.
He was known in his village for being able to sit at the bottom of a freezing lake for an incredibly long time (something it turns out he was able to do because he is a robot).
Although being a machine has not changed his friendships with his teammates, it does sometimes make him feel different and a little lonely.
Zane’s blueprints end up being used to create the Nindroid army, which inspires him to fight this new foe even harder.
While still very logical and practical, meeting P.I.X.A.L. causes him to feel all new emotions.
