Tyson was. He bit a dudes ear off and tried to break the arm of another. Let's not forget his crash out in his fight with Savarese either. Tyson was a damn savage when he got out of prison.
Wasn’t it alleged here not long ago in a quote from a book that he used to enter a fast food drive thru via the exit lane? Pretty sure he was a villain. That is some Gru-level dastardry.
It's one thing to do a couple of dirty things here and there. I believe there is an unspoken rule among fighters where you get 1 or 2, because they don't immidiatly complain. Holyfield is the biggest cheater,but he was smart. George Foreman isn't someone in the 90s to talk bad about someone,and he siad Holyfield was dirty. So did Bowe,Mike,Rahman and Lennox said he had a freaking tire to practice the headbutts. Everyone talks about the headbutts,but for some reason no one ever talked about hte low blows. Mike Post Prison was the dumbest cheater. Breaking people's arms, biting ears,biting Mcbride, knocking down the referee against Savarese, hitting Orlin Norris after the bell WHEN THE REF WAS BETWEEN THEM. When it comes to the Evander situation, I used to call Evander a cheater and a POS, and he is. But it is hard to find sympathy for Mike tbh,when Mike literally hit him after the bell first, then he is gonna complain about this later. Evander probably would have butted anyways, but Mike still hit him after the bell
I think his name was Frank Botha. I only remember two things from this fight, the arm breaking, and the KO. That KO imo probably is Tyson's top 5 KOs, Up there with Ruddock 1,Berbick and Thomas
