From what I can remember off the top of my head while I'm writing this GaoGaiGer is probably the FIRST Brave robo - "Yuusha Robo" - series from Sunrise thats being released in the US.

*Please correct me if I am wrong cuz if there was another "Yuusha Robo" series released in the US before then I want to know cuz I've never seen it in stores!!*

Ok, back to topic. ^^;

GaoGaiGer was aired in Japan in the late 1990's (I think it started in 97 or 98...wow, almost a decade ago huh!?) and from there the series not only brought back the "Yuusha Robot" series back to television (Dont remember how long the series before it aired. ^^; ) but it was also holding its own with all the other legendary robot animes out at the time.

So I'd like to hear your thoughts on the series.
