The latest pre-released minifig image is of Rose, a new character who is said to accompany Finn on a side mission in
The Last Jedi and will come in an as yet unknown set. The torso and leg print shows a non-descript maintenance workers outfit, and all-in-all it's a rather non-descript minifig that is somewhat reminiscent of the LEGO version of
Irina Spalko from the IJ: Kingdom of the Crystal Skull sets.
