Zetsuborg

Zetsuborg (ゼツボーグ Zetsubōgu) are the main monsters in this season. They are created when the Three Musketeers trap people into the Gate of Desperation, which takes away the victims dream. When they are defeated, they say "dreaming".

Appearance
Zetsuborgs are bipedal and have a giant black lock with a red light glowing from the keyhole in front of it. Their actual bodies take on an appearance related to the victim's dream.

Trivia

 * Each of the commanders use their names when they trap people's dreams. Close says "Close Your Dream!", Shut says "Shut Your Dream!" and Lock says "Lock Your Dream!".
