Sergeant Keroro, a frog-like alien invader, is captured in the line of duty by two Japanese teenagers while scouting for an invasion of Earth. After being left behind when the mission is aborted, Keroro is taken in (with some reluctance on all parties) by his captors: Fuyuki Hinata, his big sister Natsumi, and their single mom Aki. Keroro quickly begins plotting his comeback, scheming to reunite with his amphibian squad-mates (the mercurial Private Tamama, the gruff Corporal Giroro, the mischievous Sgt. Major Kururu, and the enigmatic Dororo) and renew their plan to conquer Earth (or "Pekopon", as the invaders call it)... when he's not being distracted by building Gundam model kits, or by other aspects of Earth culture. Written by Andrew P.

26 July 2011 | by zackeryburgeddSee all my reviews

In sixth grade I was a big anime fan, but I grew out of it and moved back to comic books. While I'm slowly regaining my interest in anime again, while balancing my love for American comics, I go for the not-so well know franchises. Either they are underrated or they do have a big fan base, but not as big as the heavy hitters such as Naruto or Bleach. And I'll be reviewing Sgt.Frog. Now I love both the anime and the manga although I think the manga is superior then again that's me.

Me personally my favorite two characters have to be Dororo and Koyuki. They are fun, interesting, and they are freakin ninjas! I love the other characters such as Angol Mois, Kululu, Tamama, Momoka, and many more. I think one of the strongest points that this show has is its pop culture references. Yes I am a sucker for pop culture references, if they are done right. And this show is spot on with it. They made fun of DBZ, Gundams, Street Fighter,and many more. You have to see it to understand it. I really can't much in words. All have to say is you might like it and I actually recommend the English dub.
