I thinks it’s supposed to be XJ9-CS14.

Doesn’t look quite the same. She might be based on one of the other Imperial Probe Droid builds, or a composite of two or more of them.

Here's hoping she's in a later set.

I really want to build one.

Seen the season three times so far, might require more viewings.

I think it's almost the same, as a person who owns the probe droid figure and has seen the show, it does seem that t's either the same figure, or almost the same
