You could say it's the second series of the Zoids anime, but in a different time and era. Here all the Zoids in the first series are already there, and there is nothing new or interesting. Honestly, I think this is very boring, the algorithm of this anime story is almost the same for every episode, for example, like living an ordinary life, meeting someone who will become an enemy or opponent, fighting, in the middle of a fight, Liger Zero goes and changes costumes, then comes back and defeats the enemy and wins. It's so boring to see him like that in every episode. Very different fromthe initial Zoids series which had a definite storyline and goal, namely finding Zoids Eve, in Zoids Zero there is no definite storyline goal for the MC.
There is only Battle and Battle over and over again.

I don't really recommend the Zoids Zero anime, because the story is too boring to watch.
