The Estrela toy company did not just release the U.S. versions of G.I.Joe toys, but made several changes before releasing the toys. As a result, there are many exclusive figures and toys that were only available in Brazil.
Pictured above (left) is the artwork for the four figures from Forca Fera. Pictured are (clockwise from upper-left) Tigor, Kangor, Urzor, and Leontor (Backblast with different accessories).
