Keronians

Keronians
Keronians are the humanoid frog-like inhabitats of the planet Keron. A majority of Keronians are listed in the Keron Army, and are active invaders on other planets. Keronians are from the anime and manga series of Keroro Gunso/SGT. Frog.

Appearance
Young Keronians, referred to as tad-poles, have round tails and the skin on their face is mostly white. Male adult Keronian`s tails become small stubbs and the white skin on their face recede to around their mouth. Male keronians generally achieve a fully adult body at 20 years of age. Female Keronians, however, keep their child like appearance for most of their life and when the previously mentioned physical change happens it is a sign of old age, at about 80 years old.

Note: The ages posted here are generalizations made so humans can understand the basic idea, as Keronian`s lives are thousands of years longer than humans.

In terms of clothing, Keronians have virtally none. All Keronians wear hats with ear flaps, usually a different color than their skin. Female`s hats usually feature cat-ear-like horns.

All Keronians have symbols on their heads and stomachs. These symbols represent their owners personalities, abilities, and proffessions. The symbol is decided for them by their parents at a young age, but can change at any time, whenever the owner wants to change it. For example, whenever someone achieves Sergeant rank or higher in the Keron Army, get a choice of changing their symbol to the Keron Star, a piece of technology that makes whover wears it gain authority and respect from anyone around. Most choose not to change to the Keron Star.

Society
Keron is easily the most influential planet in its huge solar system, the Gamma Storm Cloud System. They were the first to achieve space-age technology, which probobly explains why the inhabitats of planets Ahotoron and Maron look extremely similar to Keronians. Keronian society would be seen as odd to humans. Despite having a very similar social structure, a few things on Keron stand out substantially, such as the fact that they wear no clothes other than hats and symbols, both of which they effectively treat as part of their body, only ever taking them off to clean them, which they do rarely. Also the structure of buildings on Keron look very unstable, resembling either several very large dice blocks stacked ontop of each other or several domed buildings stuck together. Everyone in the Gamma Storm Cloud System and it`s surrounding galaxies refer to the planet Earth as Pekopon, because they are unaware of the fact that the primitave life forms who inhabit the planet have named it something else.

Trivia
They can stretch their arms up to as long as their body, which is probably why you sometimes see Keroro having longer arms than usual. (see Volume 14, Encounter 112)*They like humid areas and they dry up when its too hot which makes sense because they are generally amphibians
 * They are also weak in snow for there is no snow at keron
 * Keronians became prey of nyororo for their humidity
 * They have Anti-barrier on their hat that makes them invisible, but it is battery operated.
 * Despite people believing that Keronians do not have hair, in fact they do. Keroro can grow out his eyebrows but he decides to shave them (episode 58; that is why you barely see eyebrows on him); The Demon Sergeant (Keroro's Father) has a toothbrush mustache; In episode 234-b when the platoon used the time machine to fast forward 10 years, Giroro and Tamama are seen with white mustaches and Keroro is seen with a full white beard; Miruru from movie 3 has blond hair at the end of her skin flaps; Giroro's father has large bushy eyebrows and a mustache.
 * Keronians lay eggs but have only one at a time like humans. (Ex: Keroro is an only child)
 * Their teeth can grow back in at least an hour according to the anime. In the manga, they have multiple sets of permanent teeth that are stronger than the last set.
 * They have a high resistance to explosions. Keronians including the whole platoon and Dark Keroro survived huge explosions, sometimes leaving people thinking that they have died. Instead they pop out of nowhere with an afro, and a charred body. Also in the episode where GirPururu.jpg was introduced, Keroro survives when Giroro stuffs a grenade in his mouth.
 * They also seem to heal up from injuries very quickly.
 * They have a defense mechanism to smell horribly to ward of predators when they are depressed.
 * The Hinata Family, the Momoka Residence,  the Kissho Academy Newspaper Club, Sabaro, Omiyo, Koyuki  and Santa Claus are the only Pekoponians that know of the Keronian's existence
