Penguins

Not to be confused with The Commonwealth of Pengin, the Penguin Nation.

The Penguins (also known as the Penguin Tribe or the Penguin Race) are an evolved version of the avian species of the same name, native to the Southern Hemisphere of Earth. The Penguins shown within Penguins: Defenders of Antarctica are exclusively residents of Western Antarctica in the Ellsworth Region. The Penguin Tribe consists of a gigantic city, Penguin City, and employ a police/paramilitary organization called The Penguin Agents to participate in subverting the Beacon Hunt. The vast majority of Penguins belong to the Commonwealth of Pengin.

History
At some point billions of years ago, the Penguins were created and lived on Antarctica in peace for many centuries.

Eventually, they were bestowed with intelligence from the Human Race and The Legend was imparted to them.

Following this bestowing, they rapidly industrialized and quickly formed a nation known as the Commonwealth of Pengin. A massive city, Penguin City, was built, along with a protective wall and a sheet of glass. Eventually, the Penguin Agency decided to subvert the Beacon War due to environmental concerns.

Characteristics
Penguins stand about a meter tall and are hyper-intelligent. They have a dark purple-blue coat of fur with a white patch in the belly which gradients into an accent colour. They have been shown to have a variety of eye colours from orange to cyan. Penguins have a hooked orange beak and orange feet and fur-covered flippers. Occasionally they have been shown to be capable of wearing armour and wielding weapons. They are also capable of wearing glasses and jewelry. Females are capable of growing long hair. Penguins seems not to require clothing but some choose to do so in order to confer status.

Language
Penguins seem to speak an altered version of Japanese.

The Commonwealth of Pengin
(Main article here.)

The Commonwealth of Pengin is a patch of land the approximate size of the Kanto Region of Japan covered entirely by a single walled city, Penguin City. Various sub-factions are based here. The Commonwealth of Pengin is against the Beacon War and attempting to subvert it via the destruction of the Beacon. The Commonwealth of Pengin also appears to be a capitalistic society, although specific details are unknown.

Penguin Agency
The Penguin Agents are a police/paramilitary organization that act as the enforcement arm of the Commonwealth of Pengin. They are devoted to the elimination of both domestic (gangs, etc) and external (the Eagle Tribe, the Beacon War) threats. They serve as the protagonist faction of Penguins: Defenders of Antarctica.

The Three Triads
The Three Triads, or the Gangs of Penguin City, are a collection of three independent criminal syndicates native to Penguin City, typically in conflict with the Penguin Agency due to their nature.

Trivia

 * Pengin is Penguin in Japanese.
 * The Penguins seem not to resemble any real species of Penguin intentionally, although they are most alike Emperor Penguins.
 * The reason the protagonists are Penguins is because the author, Alpha Yu, used to pretend to be Penguins with his friends as a child and engaged in pretend-play similar to the plot of the series.
