One could argue that the tigress Nellie was a female hence a push over, but the facts leads to, the females are the superiors, more game, more skilled and like male lions who protect the cubs, the tigresses are the ones endowed with this trait not male tigers, adding in gameness. But that specific tigress nellie was no push over, as she survived altercations with a russian bear, unfortunately a cage mate tiger didnt:
Clyde beatty and one of his bears:
Garden City, New York, 1965, p. 279-280
“I’ve trained and handled plenty of bears…but I’ve never known a member of the species to match the brutish feat of Bill, a big brown Russian bear that I was using in a mixed group which included, in
addition to him and three other Russians, an assortment of leopards, tigers, pumas, lions and hyenas….

能和俄国大棕熊 Bill 的残暴的成就相比...

The bears and tigers grew to hate one another. There was a continual growling and snarling when they were in the arena together. Bill was becoming a moody Russian by reason of three successive paw-cloutings and nippings administered by Nellie, a tigress that had no use for bears and made no bones about it. Bill never had a chance to get back at Nellie, but he had a fine opportunity one day to avenge himself on Lil, the other tiger in the act, and he took advantage of it with surprising speed and effectiveness. It was something that had never happened before---at least, nothing like it appears anywhere in the annals of animal training---and perhaps it will never happen again.

…The boy whose job it was to hook this seat in place had been careless and it had come loose. Down toppled Lil, landing right in front of Bill’s pedestal. In a split second the bear made a leap for the sprawling tigress, grabbing her from behind by the neck. Bill had one of those unbreakable holds, and he snapped the big cat’s neck before she had a chance to defend herself. Lil died a few minutes afterward. Needless to say, the bear had a tremendous advantage in this brief encounter, but the occurrence astonished me none the less. While Bill was sure to have a big early edge when he attacked under the circumstances described, the chances were a hundred to one against his quickly getting that unbreakable hold. If he didn’t succeed in doing this, he was a goner, for tigers are lightning fast and Lil would have quickly brought her claws and teeth into
play and made an end of that overambitious bear.”

So bill the bear killed a tiger and Clydes other bear doris killed two tigers, a tigress and her mate tim:
3 tigers were killed by Clydes bears, yet Beatty holds the opinion that he thinks a bear is no match for a lion.
