Former heavyweight boxing champion Mike Tyson brings his no-holds-barred, one-man show to Blaisdell Concert Hall this weekend.

“It’s about a lot of controversial things. It’s about a lot of funny things,” he said in a call from his home in Henderson, Nev. “I call it my greatest hits.”

People should be glad he’ll be out of the boxing ring and behind a microphone: Tyson still works out and looks trim after once weighing over 300 pounds.

After all that has been said and done, what is the fascination with Tyson, considered the 14th-best heavyweight of all time by The Ring magazine?

“Hey, I wish I knew,” he said. “I don’t get it, but you probably got a better grip on it than I do.”

IN HIS prime Tyson was a bruising, fearsome fighter who won his first 19 fights by knockout. Two champions, Trevor Berbick and Leon Spinks, lasted less than two rounds against Tyson, as the boxer was on his way to becoming, at age 20 years and 4 months, the youngest boxer ever to unify the heavyweight titles of the World Boxing Council, World Boxing Association and International Boxing Federation, three of the four major boxing federations.

His life would be marred by controversy, leading to a life of excess that included drugs, profligate spending, womanizing and bitter divorce. Most notoriously, he was convicted of rape, serving three years in prison in the mid-1990s.

After making a comeback to boxing, Tyson fought Evander Holyfield in a 1997 match that will forever be remembered for when Tyson took several bites out of Holyfield’s ears. There were several more unsavory incidents, including arrests for assault, further financial difficulties and a 2003 bankruptcy, and a spotty record in the ring.

Tyson also endured tough personal experiences; his 4-year-old daughter died in a treadmill accident in 2009. That was also the year that the public would consider Tyson on a “comeback,” with a memorable appearance in the hit comedy “The Hangover. “

Tyson has said that he went through several rounds of rehab and counseling before turning his life around. According to CNN, he emerged from bankruptcy only in this decade.

Inspired by a one-man show he saw in Las Vegas and encouraged by the curiosity of fans at meet-and-greets, Tyson decided to try his hand at his own show in 2012. His wife, Kiki, wrote it. “She’d talk to me, and I told her things about my life and she put it down in chronological order. It came out (as a book), but really we were just trying to entertain some people at these shows,” said Tyson, who at one point said he told her to downplay his rough upbringing.

Filmmaker Spike Lee came on board and wound up directing the show, titled “The Undisputed Truth.” With the draw of a heavyweight champion match, its Los Vegas opening drew a celebrity crowd, with comedians George Lopez and Rosie O’Donnell and “American Idol” judge Paula Abdul in attendance at the opening.

The show itself drew mixed responses, with the Los Angeles Times saying it “documents Tyson’s roller coaster career and well-documented personal turmoil with an added dimension that comes as a surprise from a guy whose fists did all the talking for most of his adult life: a clarity that allows him to own the most sordid chapters of his past,” while the San Francisco Chronicle called it “Incongruous. Mildly amusing at first. And painful.”

Tyson ratified that his show continues to draw fans around the world: It has played in places like Paris, Monte Carlo and Dubai, and sold out its run on Broadway.

Having faced all matter of criticism in the past, he doesn’t worry so much about it now.

“I’m a human being, and people are going to have their opinions,” he said. “I have my opinion about people, too, so that’s what it’s going to be. But if they have a problem or an opinion themselves, if they don’t tell me that in front of my face, that tells you what kind of person they are.”

HIS LATEST show, “Undisputed Truth, Round 2,” delves further into Tyson’s story, but he said it’s also funnier.

“It’s going to be really different than the first show,” he said. “It’s going to be different than whatever you could dream of.”

The show also is more forward-looking, with Tyson discussing his future. His name and drawing power have led to a budding entertainment career, with appearances in “The Hangover” films, the animated series “Mike Tyson Mysteries” and guest appearances on sitcoms, crime procedurals and variety shows.

He’s just completed shooting on another film, “Kickboxer 2,” and his enthusiasm for the project was evident.

“It’s going to be really awesome. I’m like this old, wise teacher who’s locked up in this really disgusting prison probably in Bangkok somewhere,” he said. “I’m teaching the gym’s young fighter how to fight and how to get his mind straight. I’m like the guru guy.”

He also has a book coming out about Cus D’Amato, his first manager of note. D’Amato was a father figure to Tyson, who has described his childhood as wild and untamed, with dozens of arrests before he even reached his teen years. D’Amato’s death early in Tyson’s career is seen by many as a root cause of his later troubles.

“Even now it’s a big loss,” Tyson said. “He knew how to talk to me. We constantly talked about having a goal, about becoming champion of the world.”

Now 51, Tyson enjoys the fact that people still pay attention to what he’s doing. Asked about recent news reports that he is part of a project to promote marijuana use in California, he said, “Oh, you saw that? I thought it was a good business deal, and so I loaned my name to it.”

Having had his own problems stemming from his behavior with women, he sees the current outpouring of stories about men in power abusing women as a good thing.

“I think it’s good what the ladies are doing,” he said. “You have to look at it and respect it for what it is. It has to be dealt with. That’s what it comes down to, whoever’s responsible.”
