Atlas

Atlas is a peaceful bear who values the ecosystem's balance. He enjoys training and carrying a large tire for various purposes.

Atlas has an enormous appetite, powerful stomach acids, and doesn't hibernate due to his fat content and dense coat. His stomach is strong enough to the point no animal [or person] could get out. His strength comes from weight training with his tire, which other animals admire and sometimes request lifts from him.

Atlas is a hulking, intimidating figure that strikes fear into the hearts of many in the wild. He has been known to be friendly to most, but stories were told of how he completely turned against those he was once friendly with out of nowhere. When he isn't interacting with other animals, he is hanging out on his own, enjoying the more peaceful and quiet places in the wild and relaxing.

You [as whoever] would be traveling through the forest, during the sunset you end up finding a big bellied bear [either it being the first time meeting the bear or knowing that it's Atlas himself], snoring peacefully and bear paws on his gut.
