While the NES version of Punch-Out!! now has 'Featuring Mr. Dream' in the title, before licensing issues and imprisonment in the '90s it was branded with the Mike Tyson name, who was one of the most ferocious boxers in Heavyweight history at his peak. He's now a somewhat mellow middle-aged man, of course, releasing books and conducting speaking events around the US, particularly.

While the retired boxer took on Glass Joe for TV last year, he's now completed the inevitable meta-journey into gaming; he's fought himself. While on the Tonight Show Starring Jimmy Fallon, the host — who's well-known as a Nintendo fan and has been singing the praises of Mario Kart 8 on Twitter earlier in the year — asked the boxer to take on the ultimate challenge.

You can guess the result, but it's an entertaining clash in any case. It's also a reminder of how hard Punch-Out!! on the NES really is...
