Nindroids are highly (artificially)
intelligent humanoid robots with unbelievably strong programmed fighting skills from Ninjago. While most of the Nindroids were created by
the Overlord and are evil, there are some
exceptions. The most notable is Zane, the Master of Ice and the sweetest Ninja on Sensei Wu's team. The evil Nindroid's design was based on Zane's. The other exceptions include Cyrus Borg's security droids and Echo Zane. But any of them could simply be reprogrammed.
