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

Keroro Gunso.
What in space can I possibly say about Keroro Gunso?

I'll start by saying that there's not one character that I dislike in this whole series. Even ones I didn't warm to at first eventually have episodes that make me not just like, but adore them. And boy, does this show have a huge cast of main, secondary, and minute characters, all of whom are bursting with charm.
When I finished episode 358 -- yes, I watched every single one, my longest anime to date! -- my upper lip wobbled and my eyes genuinely filled with tears. Keroro Gunso is like watching a read more

Probably one of the most underappreciated animes watched so far. A mix of cartoon and anime at the same time. Literally something what a child like me in my old days that he/she watched.

there are some epsiodes are good and are bad. Artstyle is hard to rate because in the old years the artstyle was very funky and simpistic and as late 2010, it looks very normal and became on-par to other animes, but as far as it goes its really decent because when I look at them more closely they improved as years passby, and I’m proud they really make the anime very read more
