Xpanders Attack 4x4/ Gun Battery #5504 complete In Box Vintage Galoob.

This is pretty awesome!

The power transforming button works, but when it comes to fully transforming, the human hands have to help it to completion.

It's from 1989.

It's complete with the stickers and little dudes and flag.

The left back will not open completely. It is about 1/2 centimeter shy of opening completely. I tried to picture it.
