Rangers from Katmai National Park and Preserve, the Katmai Conservancy, and Explore.org created Fat Bear Week to raise awareness about the efforts bears put into bulking up to survive the winter. It has become a cherished yearly event across the world and the internet.

The adorable single-elimination tournament is in its ninth year, and the Explore.org staff and park rangers revealed the chubby competitors Monday night.

The 2023 entries are all chokers with great stories. Some are old favorites, like the 2022 defending champ Bear 747, while others are newcomers to the battle of the biggest and fattest.

This year's competitors include old favorites and new fuzzy faces, like the most decorated winner of them all, 480 Otis, a 28-year-old bear that has won the competition four times.

Also in this year's smackdown are 151 Walker and 128 Grazer, as well as two new bears to Fat Bear Week: 164 Bucky Dent, named by fans because of a tuft of hair between his eyebrows, and 284 Electra. There's also former winner 435 Holly, whom fans have described as a "toasted marshmallow."

Last but not least, 32 Chunk, a bear Katmai Ranger Naomi Boak describes as the "lightbulb-shaped Leviathan," is also in the running.
