My favorite has to be Kazuyuki Fujita vs Thompson - simply because I have a soft spot for Fujita. I always felt he was being thrown in to feed the wolves. Fujita was not a good fighter by any means but the big guy had such a big heart - even bigger than his head and he won the hearts of many during his epic battle with James Thompson.
Fujita was just as stubborn as Vegita. He would fight while knowing his efforts were futile. He would take punishment after punishment - knees after knees, and if the fight were to last 100 rounds, he would still keep coming forward until a blow eventually kills him...
...And that is exactly what happened in Fujita's fight with Thompson. Fujita ate countless knees and absorbed countless punishment but his samurai spirit remained intact. And like a samurai, he mustered his very last bit of strength to deliver the fight ending blows to his opponent, James Thompson. All the while, Fujita could barely stand himself. This fight is a testimony of will, courage, and self preservation and it is only through warriors like Fujita - that we were able to witness such feat.
Fujita, you are a legend in your own right.
