Keronian

Keronians (Keronjin) are the natural inhabitants of the planet Keron. A planet that is said to be

the fifty-eighth planet in the gamma planetary system.

Nyororos are the natural enemies of Keronians. They suck water from Keronians whenever their water levels rise, essentially dehydrating them. The keronian sucked dry doesn't die however.

The Viper clan is a race of snake like aliens that resemble cobras is a major rival to the Keronians and have been at war with them for many years. This is more than likely a refrance to the fact that in the real world, frogs are part of a snake's diet.

Externally, Keronians appear to have a small body, with heads bigger than their body.

Keronians are frog-like amphibians that grow tails when young and breathe in air. They are sensitive to changes in atmospheric humidity. Due to their frog like DNA, it is likely they descended (evolved) from frogs. In like manner how humans evolved from monkey like ancestors.

Physically keronians are short creatures. With adults standing only about two feet tall, when compared to most species. Their skin color, comes in a rainbow of different pigmentations. Such known colors are. Green, red, blue, dark blue, light blue, black, and yellow. On their faces, male keronians have white skin (Charcoal gray in some)  extending from right above their mouths down the side of their face and to their necks. While female keronians and young ones, (male and female) have this feature much higher on their face. Extending to around their eyes, however with males this will recede down to their mouth as they grow. As said before Keronians grow tails in their young ones. Males losing their tails as they grow. Much like how earth tadpoles grow tails and lose them as they grow. There is no explained reason as to why females don't lose their tails and never changes face.

On their belly most members of this race wear a symbol of sorts. Some of them don't have one. The design and color of the symbol is different for each individual who has one. It is never really said if this symbol is a birth mark, or just a tattoo given to the keronian after birth, or its just a sticker.

On the head, almost every keronian wears a hat of some kind. Some however have hair or maybe a wig. The color of the hat varies to each individual, and also carries the same symbol that their belly does. The style of the hat also varies as well. Some wear a simple hat with an ear flap on each side. Other keronians though, particularly those who have positions in computer programing and or hacking. Wear hats with headphones instead of ear flaps. And almost all females will have two cat ear like things on the top of their hats, but some have different two points design instead of cat ear-like on their heads, where as males will have nothing on the top. While even fewer have helmets instead of hats.

History
Not much is known about their prehistory. But in the earth year 2004, a Keronian platoon commanded by sergeant Keroro landed in Japan to invade Earth (Whom they called Pekopon or Pokopen ). They met a local family (the Hinatas) and built a secret base in their home to start the invasion. However, they started a friendship with the Hinata family (and corporal Giroro fell in love with Natsumi, the eldest daughter) and renounced their invasion of Earth. Another platoon, commanded by Garuru. (Giroro's older brother) tried to invade the planet, but Keroro's platoon prevented the invasion.
