Unsuspecting inhabitants of the planet Earth are going about their business, enjoying a bright and particularly beautiful sunny day, when a young Japanese boy spots a shiny object falling from the sky... Has an alien invasion finally begun?

Elsewhere in Japan, Keroro, frog sergeant and leader of the Space Invasion Army Special Tactics Platoon of the 58th Planet in the Gamma Planetary System, has discovered the perfect hideout. He infiltrates the home of the Hinata family in an attempt to establish a headquarters that he and his troops could use to prepare for world domination... but earthlings Fuyuki and Natsumi Hinata are too much for him to handle! Natsumi instinctively calls them out of hiding, leaving the hapless sergeant no option but to reveal his secret identity. The two siblings soon welcome the sergeant to their home, all thanks to Fuyuki’s generos—err... curiosity.

The Sergeant has successfully infiltrated his first target area! Or has he? Join Keroro Gunsou in his dastardly attempt to take over the world!

This my friends is the only Mecha Anime that counts.The Laughs, the feels, the action, it truly has it all. It has guided me on theway to be a better man, and to this day I still follow the way of the frog diligently. More than an anime you'll be looking at the very essence of life. Keroro Gunsou is more worthy of an oscar than Leonardo F* Dicaprio. Truly a work of art. I am NOT kidding, this is ART in its purest form, the Joconde ? pff, ridiculous... Watch it, and next time someone at a fancy art gallerie asks you 'so, what's read more

Overall: 10/10
Usually I would base my overall rating off of the mean score of each aspect provided, but I love this anime way too much to give it anything lower than a 10. This was the first anime I ever watched as a kid, and it's the only anime that still makes me laugh out loud every time I watch it. Definitely the funniest anime I've ever seen without exaggeration. It's definitely not for everyone, but in my opinion there'll never be anything as perfect as Sgt. Frog lol

Story: 5/10
The story sort of gets lost throughout the series. I mean, half of this anime read more

Well before otaku-queen Konata Izumi's (LuckyStar) sitcom ever aired, there existed a little green alien named Keroro that came down to command and conquer this planet. How he will manage to pull this off even Keroro doesn't even know himself. This is where the viewer comes in. We're all there for the wild ride that is the Keroro Universe. This whole series is told in a sitcom format where almost every episode will end with little to no change to the story. If you don't know if this is a series for you just read the lyrics of the first opening credits:

"March on forward! Let's read more

I started to become a fan of Sergeant Frong (aka Keroro Gunsou) when the manga first came out here in the US. At first I though this was gonna be some manga I wouldn't like but eventually I fell in love with the crazy antics of the Alien space Frog, Keroro. I began to watch the episodes on Youtube and they were just as I expected to be. Though the show seems kiddy like, they have alot of adult themes. It also has sketches within the anime of scenes of many famous Japanese movies and Animes (Gundam the most).

The story begins with Fuyki and read more
