Martial arts master fights bulls

[snopes]

Comment: I've heard, and am entirely convinced is true, that the Karate
Martial Artist 'Mas Oyama' fought and beat 52ish bulls with his bare hands
and managed to kill 4 of them on the spot but few of my friends beleive
its true. I think its a great legend too and was wondering if you could
try and confirm/debunk this legend?

Wikipedia article confirms killing bulls, but not the number.

Oyama was fond of remembering that his first attempt just resulted in an angry bull. In 1957, at the age of 34, he was nearly killed in Mexico when a bull got some of his own back and gored him

A very quick Google of him seems to confirm the record.

Only anecdote supports the story. He apparently did some bullfighting, but nothing confirms that he did exactly what is said of him.

Here is a video clip of him messing with a younger and smaller animal. It's a highly-edited bit and I doubt that he knocked the horn or even killed this one with a blow...
