This is the Greek version of Oberon, marketed as a Astrowarrior instead of a Micronaut. The box is a very large 9 and 1/4 inches wide by 10 and a 1/2 inches tall
Although you can't tell here, there are minor differences that distinguish this Oberon from others. The red detail color and plastic, normally an opaque orangish red, is instead a semi-transparent orange color. This is especially noticeable on the backs of the rocket launchers, where you can see the inner workings and fasteners. A minor difference, but significant.
These toys were distributed in Greece by El Greco.
