The Box's Brother (Emerald2019)

the box's brother is the box's brother who only appeared in episode IV (confirmed as the box's brother) and III (as his replacement and on non-April Fools), though he is going to return on ZER0 1.
== Development ==
As the box III was coming in for another episode, there was a decision on whether or not someone should be added. This normally came out of nowhere, but The Box's Brother came to the box's place only as her replacement.
