Mike Tyson, famous for his "nuclear fist", is becoming a hot topic when he aims to return to the ring at the age of 54.

This is a training scene that Tyson recently posted on SNS.

The speed and destructive power of the mid 50s are unbelievable.

Tyson said he was making his body to participate in a charity match to help the underprivileged.

Tyson, who was the youngest 20-year-old heavyweight champion in 1986, enjoyed an era with a strong punch, but in 1997 he fell into the quest to bite Holly Field's ears.

In 2002, he challenged Lennox Lewis, the champion of the time, to recover, but left the ring in 2005 after losing miserably.

"I don't need to do anything anymore because I'm already in the Hall of Fame," said George Foreman, who was the oldest heavyweight champion of all time at the age of 45 to promote Tyson's return.

American media say Foreman's current worries are about worrying about playing as a heavyweight boxer at age 54.
