The Brazillion Falcon stuff is 1/6 12in. Gijoe scale but looks like some of the Super Joe designs. Many great Sci Fi designs there.
The Dynaman had limited distribution in USA so it is possible to find but better to look for in UK.

The Space Acadamy and Goldrake figure use Super Joe bodies.

Not sure how I found them but there are a few Estrela Falcon commercials on youtube

I'm pretty sure the Falcon stuff used the 1/6 scale GI Joe muscle body. The smaller Super Joe body design was based off of the muscle bodies.
