Recommendation: Very funny short parody of magical girls/giant robots anime. Requires no prior knowledge of the robot series' that the characters are based on to enjoy. Definitely give it a try. Robot Girls Z is only 3 episodes long and there is no story to speak of, so this is going to be a short review. The main 3 robot girls and the 3 villains fight each other and the villains get owned, and then they bring in new one-off villains to fight the robot girls and the new villains also get owned. Rinse, repeat. They come up with new bits andjokes each time to keep the formula feeling fresh though. The Underground Empire's evil plots all have a vaguely Wile E. Coyote quality to them where you know they're doomed to fail from the start, but watching the specific ways their plans unravel always makes for good entertainment.

The main downsides here are laughably bad animation, which is so cartoonish and tongue-in-cheek that it almost feels intentional, and the unnecessary ecchi bits with girls' clothes constantly getting blown off. It added nothing and just felt really uncomfortable given how young some of the girls look. That being said, it's a small part of the series and easy to ignore, and the series overall is funny enough that it's worth tolerating some brainless fanservice for it.
