It sounds like you're referencing a storyline involving the Spy Ninjas, particularly focused on their rivalry with Project Zorgo. In this context, the leader of Project Zorgo, known as "PZ Leader," has been portrayed with various dramatic elements, including hiding technology behind his face and pretending to be something he is not.
While I can't provide specific episode details, this type of plot often revolves around themes of identity, deception, and resilience against challenges. The PZ Leader's recovery behind a life support device could symbolize his struggle to maintain power or his humanity in the face of defeat.
For precise details, it’s best to watch episodes of the Spy Ninjas series, as they often feature evolving storylines and creative twists!
