Sentai Badass Villain Edition: Doctor Man Fools the Big Three!
There's no doubt Doctor Man is one awesome badass. He did blow his cover way back in episode 19 when he said Prince was his son. Neither Mason nor his comrades were aware of Doctor Man being human until episode 19. Doctor Man had prepared a scheme that effectively proved he doesn't easily fall down.
In this episode, the Big Three finally decided tio get rid of Doctor Man. That's it, we're through having a human for a leader. Gear was a mechanical empire and they thought that Mecha Humans should not be led by a human being. The problem already started when Prince was introduced. Mason never expected Doctor Man to be a human. The fact Doctor Man said, "A robot can be replaced." made everyone startle. They couldn't believe their leader was a HUMAN! So they conspired to kill him, it looked like he died but not if you know how terrifyingly cunning Doctor Man is!
