Israel Adesanya Part 2
Adesanya enters this list for a second time after an incident in 2023. He finally defeated his rival Alex Pereira in their fourth meeting and the relief was palpable. But he celebrated embarrassingly as he showed bad sportsmanship. Pereira knocked Adesanya out cold in a kickboxing match seven years before. Then the Brazilian’s six-year-old son mocked the stricken fighter.

He collapsed to the ground as if somebody shot him. Adesanya showed that he never forgets because he emulated this celebration after KO’ing Pereira. He cruelly mocked the now-12-year-old boy. Many critics said that this was unnecessary because he was feuding with a little boy (via The Mirror).
