This R7-Z0 figure was a build-a-droid figure and was released during The Legacy Collection's wave 1 in July 2008. The astromech droid never appeared in any of the movies, and was only mentioned in The New Essential Guides To Droids book.
R7-Z0 has the typical 5 astromech joints (dome, 2 legs, 2 ankles) and a very cleanly applied paint application with no dirt or battle damage markings. Hasbro included two booster rockets with the droid which can be plugged into the sides of each leg. They fit tightly and look overall good. If you want to have the astromech stand on two legs you can remove the middle leg. All legs have little rolls in them, so you can move the figure around in your display. There is no sensor scope in the dome, hence no clicking sound when you turn the dome.
There were no weapons or accessories included other than the booster rockets. All in all, it's another decent astromech droid which has not been done before.
There was no packaging text for R7-Z0. The figure was a BAD (build-a-droid) figure and could only be obtained when figures with all the individual parts were purchased and then assembled.
