“Iron Mike” Considers Himself Invincible in Prime Legendary American heavyweight Mike Tyson considers himself undefeated in his prime, when he became the youngest heavyweight champion at 20 years old. “Yeah, there were a lot of moments where other people started winning and I lost the drive. But deep down, everyone knows that if they fought the best version of me, it would be the end. It's just no chance for them,” Mike said. Earlier, legendary heavyweight Mike Tyson recalled the confrontation with Pinklon Thomas. In 1987, Tyson knocked out Thomas in the sixth round and defended the WBA and WBC titles.
