Giant Ninjas were enormous Ninja henchmen roughly the size of Giant Clank, and were first encountered in Holostar Studios during the filming of the Secret Agent Clank episode. They were hired by Maximillian in the episode.
The Ninjas would be a little difficult to hit since, being Ninjas, were incredibly agile and occasionally difficult to target. They had the ability to momentarily stun Clank (Giant Clank) with a hit of their swords, causing significant damage. They also threw shurikens from a distance. The easiest way to defeat the Ninjas was to use Giant Clank's special attack, knocking them down, then fire missiles at them and finish them off with a melee attack.
