|The Big Metal Door|
|First Seen||Episode One|
|Last Seen||Episode Three|
The Big Metal Door is one of the main objects of mystery. The door is located in a dark section of the Raza. So far it is only known by a few of the Crew, but so far no one has been able to open it as it is kept closed by an alpha numeric lock.
In Episode Five, Five lead the whole crew down to the door, so now the whole Raza crew knows about it.
In Episode Six, Five ventured into the memories in her head to try to acquire the doors code.
- A difference in the comics compared to the show, is that Marcus managed to open the door himself by the end of Issue 4. What it contains though, wasn't revealed.
