So I guess this is actually supposed to be a MECH of some sort. Being 3.75″ it fits in well as just a regular droid though.
This figure is part of the Super 7 Robotech ReAction line made in 2017.

Amazon still has a couple of these as well as Ebay but both are marked up. BBTS and Super7s website was sold out.
