Bear

The Bear is a deutergonist that represents the Soviet Union; however, the Bear does represent 3 other countries as well;
 * There is a bear with a red symbol on it's chest that represents the other bear's leader. This might be the USSR but with the Chinese word for “father” on its chest, or the Bear may represent Lenin.
 * The first bear has 1 hair with a word "大". This represents Russia. The Chinese word 大 means eldest or first.
 * The second bear has 2 hairs with a word "2". This represents Ukraine, and how Ukraine is the second to the Soviet Union.
 * The third bear has 3 hairs with a word "3" This represents Belarus, and how Belarus is the third to the Soviet Union.

Belarus and Ukraine are used mainly as background characters; whilst Russia has two episodes of him.

Animated Series
The Bear is very loud and extroverted, mostly showing this side around his friends and best friends. He also has a brotherly like side to him; being the father-figure to many characters (North Stick, Hare, etc) however with his enemies, he is mostly distant and disconnected. Like the other main characters, Bear does have his childish moments, mostly when he is drinking alcohol (a running punchline of the show is that Bear is an alcoholic) and like Hare, Bear can be angered easily, especially when drunk, but he does not have anger issues like Hare, and does not have a demonic form. Like Eagle, Bear owns his own weapon shop, called Bears Taobao Shop. It is unknown what Bear sells but it’s implied it is guns.

Webcomic
Unlike in the animated series, Bear is not an alcoholic in the webcomic. He is much more calmer then in the animated series (regards the Korean War as ‘ little kids affairs’) and mostly pisses other animals off with his laziness and unwillingness to solve disputes and fights he indirectly causes. Despite receiving tons of threats and insults, Bear retains his calmness. It is implied ‘Little Goats foster father’ could be Bear or Eagle, but most likely Eagle. Bear is featured 9 times in the comic, 2 times as a background character.

Relationships
THE HARE - FRIEND-ENEMY - The Bear and the Hare are friends in most of the episodes; Bear serves as a fatherly like figure to Hare and teaches him about weapons and military, whilst Hare gives his contributions to the relationship. But in one episode,  they decided to make a line across to prevent each other from coming to each other's country. This was later trespassed multiple times by Bear.

In episodes with the campus metaphor, Bear also gossiped about Hare along with Eagle and even said he bit 3 people, effectively shunning him from the rest of the group. Seeing as Sino-Soviet relations started off good but quickly soured in their last years, we can say the Hare and Bear are a mix of friends and enemies. However, when the Bear dies, Hare actually goes to his funeral and shows his respects.

THE EAGLE- ENEMY - Friendly banters between them are mostly sarcasm with a tidbit of irony. Although they do work together to gossip about the Hare at the campus and to not allow Hare to use nuclear bombs; they don’t do anything with each other much, and prefer to stay away from each other. When one leaves the other enters. When Bear dies from old ageand Eagle sees Russia, Eagle and Bull laugh him out of the campus, despite the fact Russia just went to his fathers funeral.

NORTH STICK - FOSTER-SON - Although Bear and North Stick are related, Bear shows little to no care for Stick in the animated series, but in the web-comic, he is implied to have taught N.Stick his fighting skills and how to become a disciple according to Bear.
