|Age||Possibly between 25-45|
His blood type is O. Watanabe has stated that she played Keroro as someone who was about 45 years old. Keroro described himself to be a child when Nintendo started selling the Game & Watch systems, which would place him somewhere between his late 20's and early 30's. However, since Keroro knew Angol Mois since she was a young child, and was already an adult at this point, this would make Keroro at least older than 500 years old. Alternatively, he might be around the same age as Pururu, (which would be around 30) sice they have known each other since childhood. His body fat percentage is 30%.
Keroro's name comes from the japanese onomatopoeia, "gero", the word for the sound a frog makes (ribbit)
AppearanceEditKeroro's body color is green. accompanied with yellow hat (or headgear) with a red star mark in the middle (a yellow star is also seen on Keroro's stomach). According to Garuru, the star is the symbol of the Keron army as well as its commanding officers. The star itself has the ability to lend its dignity to the wearer. However, since Keroro lacks character, the effect is nullified while he wears it. When Keroro is met with an explosion, he suddenly grows a large black afro. He also has other wigs on in various monents (i.e. trying to fool a Nyororo with his crossdress as a woman w/ black hair), but usually his hat is under the wig. One episode, he takes his hat off to wash it. He wears a red cap as a temporary replacement. He is barely seen with eyebrows. In the Funimation dub at least, Keroro said that he used to keep his eyebrows, but years before he met the Pekoponians, he wanted to toughen himself up. He cut off his eyebrows along with temporarily restraining himself from building Gunpla (Gundam Models).
WeaknessesEditAccording to the anime in episode 123, Keroro's biggest fear is his own father. His others fears are broken Gundam models, the invasion timer running out, and overstocking the Valentines candy (according to the fact that Keroro freaks out when he sees these items in ep 123). Whenever Fuyuki says the word 'friend', Keroro becomes consumed with feelings of guilt. In addition, he dislikes capsicums. He also has a tendency to purposely slip on banana peels, due to his actor personality. Keroro is also a drooling otaku for all things Gunpla, which is by far his biggest weakness. He also lacks skills in his homework. Even if he does it all, he will probably fail it because of the wrong answers. Along with the other members of the Keroro Platoon, Keroro is afraid of the Butt Firecracker.
Whenever Keroro sees a banana peel on the ground he steps on it without fail, as it is apparently his devout wish to entertain the masses. In the FUNimation dub, the narrator says he does this because he has an acute case of Hilarity-itis. On episode 154, he still slips on the banana peel, even though he did not see it. Luckily because of this, he saves the world.
Strengths EditBecause of his everyday life as the house cleaner in the Hinata household, Keroro is an exceptional cleaner and curler. He became a natural at curling because of all the excessive sweeping Natsumi made him do. Though Keroro often displays no combat prowess whatsoever, he was responsible for the scar across Giroro's eye. Another example is when he slapped Dark Keroro so hard, he out seat and crashed into a wall. Also, one episode when the Keroro Platoon Emergency Alarm went off, Keroro took a 100-ton hammer and smashed it. In the "Birthday Blitz" encounter in the manga, Keroro easily took out Tamama with a jump kick and snuck up to Kururu locking his arm up in a hold and threatened to break it. Another instance of his strength is in episode 44; he is able to hold back Kururu's mini sub with a fishing line. But one must remember that Keroro is a trained Keronian soldier, an instance of this is his knowledge of mechas. If Keroro is exposed to an environment with high humidity, he will slip into a state of mind where he is his former self from "Back Then". During which, he will actually act as a more competent captain, issuing Natsumi's restrain and going forth with the invasion of earth. In the anime, Keroro of back then has the power to throw energy balls. The only things that can free him from this mania is either Fuyuki's rage, or an attack by a Nyororo.
Keroro also gains a burst of energy whenever he eats starfruit, which, according to Kururu, has many qualities of Keronian medicine.

Keroro mostly speaks in the first person. He refers to himself as waga hai in Japanese.
Keroro usually ends his sentences with de arimasu, which roughly translates to 'that is it' and is a standard military sentence ending. Keroro says a repeating gerogero when resonating. Whenever Keroro is scheming, he emits a raspy Ge~ro gero gero... or Gero Gerori. Lastly, whenever he speaks English words, such as radio or no problem, he rolls any Rs in it. He also speaks an English no, no, no, no. He has also said "AHH! Good Timing!" in episode 285.
In the Funimation dub, he usually uses "frog" in the place of profanity along with some of his platoon members; for example, "what the frog".
ChildhoodEditLong ago on Planet Keron, Giroro, Pururu, and Zeroro were childhood "best" of Keroro. Keroro had a "Go to the place where one is told not to go, and enter the place where one is told not to enter" way of life, which often led the four friends on numerous, often dangerous, adventures. Inspired by his father, a famed war veteran, Keroro had his sights toward becoming a soldier. He would often wear a fake Keron star on his chest, hopeful of becoming a captain. Keroro set his sights toward becoming a soldier, and spent much of his youth in military school, where he met Kururu and Tamama and formed the Keroro Platoon.
Life with the Hinata familyEditKeroro lurked in the Hinata household until he was discovered by Natsumi and Fuyuki, after which he was captured. With the Kero Ball, his weapon, taken from him and his army having abandoned him, Keroro easily surrendered, at the same time becoming Fuyuki's friend. The freeloader (formerly a prisoner of war) becomes troublesome for the Hinata Family. Each time he is found guilty of something, Natsumi physically abuses him to no end. Most of the time, when something strange happens, she automatically blames Keroro and yells at him. But now, through being the housekeeper of the Hinata household, Keroro has become familiar to living an adventurous life on Earth.
His favorite dishes include fried potatoes, dango, carambolas, and caviar. He has also mentioned that he loves "cow flesh", which is just beef. He also likes making Gundam models, watching anime, and reading manga (Captain Geroro). He likes starfruit. His best friend is Fuyuki Hinata. He loves shiny baths (being the first to take a warm bath after the tub was recently cleaned).
In the Funimation dub he happens to like cartoons.
Keroro hates the sound of styrofoam rubbing together and people who hate Gunpla. He also hates it when Natsumi harms him or gets angry at him. Like almost all other Keronians, he hates Nyororos.
- Fuyuki - Upon their first meeting, Fuyuki took an interest in Keroro. They eventually bonded, Fuyuki becoming Keroro's partner and often stays and helps Keroro, sometimes unwillingly.
- Natsumi - Natsumi downright considers Keroro a nuisance, calling him Bokegaeru many times. They show an intense rivalry, but this actually shows a mutual respect deep down.
- Aki - Aki showed an admiration for Keroro, and was inspired by their look for an idea of a new manga. She now considers Keroro and the rest of the Platoon them as part of her family. As in the first episode.
Keroro platoon and PururuEdit
- Dororo, Giroro, and Pururu - Dororo and Giroro have been friends with Keroro since childhood. Keroro often led the two on adventures and playdates, as well as getting into trouble, especially when he exploited Dororo (Zeroro at the time). Pururu later joined their group, they have since remained together until adulthood when they separated. Keroro developed a crush on Pururu after they met again.=====
- Tamama- Tamama has a huge crush on the Sergeant, affectionately calling him "Gunsou-san". Keroro, however, remains almost 100% unaware of his crush on him. Tamama often goes to extremes to try and earn his affections, despite this, Keroro considers him a faithful subordinate and friend. There is one instance where Keroro might get it that Tamama loves him in "episode 293" when he reads a fan letter saying that Tamama loving Keroro is perverted.
Angol Mois - When Mois was younger, she and Keroro played together. After they meet again in Pekopon, Mois started to call Keroro "Oji-sama" (Uncle) as a result of their bond. She remains in the platoon, serving as a general maid and secretary to the Platoon. She also harbors romantic feelings for Keroro, however he does not return these feelings and seems to be completely unaware of them, nonetheless he cares for her as much as he does the rest of his friends
Costumes and transformationsEdit
Keroro in an afro wig and funky disco clothing, complete with fringes and glitter. He ends his sentences in "Me-ow!" and is victim to uncontrollable dancing. This is parody of Dance Man, who in turn wrote the theme song, Afro Sergeant. Keroro also inexplicably sprouts his afro whenever he becomes burnt.
Keroro's helmet changes as a parody of Son Goku's super saiyan or Sonic's super form. If this form changes his power level or not is unknown, however it does allow him to move 4 times his normal speed as well as give him flight abilities. He first used it in the manga to rescue Tamama from "Dark Momoka" when both character's first officially debut.
- (あの頃ケロロ Anokoro Keroro)
Keroro's body becomes glossy when the humidity of the environment has reached a level higher than that of Keron. "Back then" is the time when Keroro still lived in Planet Keron. His combat power and intelligence increase threefold, as evidenced by Keroro's ability to take down Natsumi with but a whisper into her ear. However, because of his strengthened biological reaction, it is easy for him to be discovered by hostile space aliens such as Viper and Nyororo(Sucks the moister out of him). His speaking style also changes during this form. In Part B of Episode 127 of the anime, parodies of Ultimate Muscle and Mobile Fighter G Gundam are seen when Keroro enters this stage
