#2. Curtis Axel held the Intercontinental Championship

The son of former Intercontinental Champion Mr Perfect added his name to the lucrative list of title holders in 2013. Curtis Axel was immediately given a huge push in May 2013. He started a brief feud with Triple H before scoring count-out victories over then-WWE champion John Cena.
Following this, he went on to compete for the Intercontinental Championship. He won the championship at the Payback pay-per-view event, defeating Wade Barrett and The Miz in a Triple Threat Match. This marked the only time in WWE history that a father-son pair had won the Intercontinental Championship.
In an interview with The Carroll County Times, Axel spoke about winning the Intercontinental Championship:
"Dude, it’s unbelievable. When I got put into that Triple Threat match at Payback, that was the first thing that crossed my mind — that I had an opportunity to win the title that my father made famous in the ’90s, the Intercontinental Championship. And if I were to win it, we’d be the first father-son duo to ever hold that title. So that whole week building up to the pay-per-view, that’s all I could think about. My grandpa was like, if you win this, it’s going to be crazy. So when I did win it, it was pretty emotional. My dad was the first thing I could think of when I grabbed that thing and I held it up." Curtis Axel said. (h/t Wrestling News.net)
Axel's reign lasted 155 days before he lost his title to Big E on the November 18th, 2013 edition of Monday Night Raw. Long live Axelmania!
