Gorilla Wins Because It Is Bigger, More Heavier And More Intelligent. Gorillas And Giant Pandas Look Like Eatchover And Act Like Eatchover As They Both Eat Bamboo. Sorry If This Offends You In The Gorilla Killing The Giant Panda Part.
Neither are bears but I think a Giant panda (not a bear but a raccoon) would win as it is larger than the koala (actually a marsupial).
koala because better
depends
Pandas are more poweful than koalas, and quite a bit larger. The panda would kill the koala if they fought. Even the smaller red panda would win against the koala.
panda.
Black bear
the bald eagle no panda bear they are fluffy
a panda
A chihuahua would win, they bite like hell and the koala will just be high on Eucalyptus
Definitely the bear would win.
The atlas bear would win.
A single bear would win against a single wolf.
The black bear would win.
The tiger would, Brown bears make up 1-1.5 % of there diet. Bears may be heavier but the tiger is faster and better fighter then a bear. Tigers are also very muscular compared to a bear that's more fat then muscle. The Siberian tiger could tale down any bear you wish; Koala, black , teddy, polar, panda, Kodiak, Grizzly
The grizzly bear would probably win
