#6 WWE Intercontinental Championship
The WWE Intercontinental Championship has been around for well over forty years at this point. Pat Patterson was the first to win it back in 1979. The belt's been known as the workhorse title for the majority of the time it's been around, though it's also a stepping stone to the top of the card.
Many former Intercontinental Champions managed to climb the ranks and eventually reach the top of the mountain. Randy Savage, Ultimate Warrior, Bret Hart, HBK, The Rock and more have used it as a gateway to the WWE Championship.
Another WWE Superstar that did just that is Jeff Hardy. The Charismatic Enigma first won the gold in 2001 when he was just 23 years old. He'd win the title four times before finally getting the WWE Championship in 2008. Hardy won his fifth Intercontinental Championship back in 2020.
#5 WWE United States Championship
This entry is going to be a little different because technically the youngest United States Champion ever came from WCW. David Flair was given the championship by his father, then WCW President, Ric Flair, back in 1999.
But going by WWE Champions specifically, we'd have to cut out David Flair. Actually, we'd be cutting out the top three on the list. Not only is Flair at the top, but he's followed by Dustin Rhodes and Ricky Steamboat.
Fourth in the list is former WWE Superstar Carlito. He won the title in 2004 at 25 years old when he defeated John Cena.
#4 WWE SmackDown Women's Championship
Alexa Bliss may be too busy haunting Monday Night RAW to focus on championships. However, back when she first showed up on the main roster, her eyes were on the prize. Soon after debuting for SmackDown, she challenged Becky Lynch for the SmackDown Women's Championship at WWE TLC 2016.
She defeated Lynch in a tables match, and became the second woman to ever hold the gold. She also became the youngest to hold the title at 25 years of age. So far, nobody has been able to take this accolade from her.
