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!

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:

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

Keroro Gunsou is one of those Anime-series you would think is meant for a very young audience due to the art style. "Looks like Pokemon" is an usual comment for this show. You couldn't be more wrong. In the USA, this show would've received a Teen rating, nothing less. And why? Because this Anime is filled with surprises: Parodies of 70-90s Anime, Nudity and the ocassional episode with outright disturbing scenes.

The show sorrounds a group of five frogs, named "The Keroro Platoon". Their job is simply to invade the earth and control everything there. With over 300 episodes with the same plot, it becomes rather read more

When I am watching Keroro and his antics to try and invade Pekopon, a.k.a Earth, I get many mixed emotions. I am usually laughing really hard, then I am like "Huh? What just happened?". And some episodes make me cry, but that is very few. For some reason, I like my shows to give me mixed emotions because I like to be kept entertained throughout the show, and Keroro gives me that. I also love the music. The music is very bubbly and happy. It makes you want to get up and dance. The art is not like your traditional Japanese art, but it is read more
