"Zoids" was on comic magazine and TV animation when I was around 10 years old.
Nowadays, Kotobukiya, Japanese scale model manufacturer release HMM (High-end Master Model) series Zoids.

I've got one of HMM Zoids, "Command Wolf Barad Ver.".
This one was limited edition, but re-released in June.

I spent about 10 hours to build it.
It was difficult but fun.
