5 youngest WWE Champions of all time

#1 Brock Lesnar (25 years old)

Lesnar flattens the Great One to be the youngest WWE Champion ever.

When Brock Lesnar appeared on the RAW after WrestleMania X8, the WWE Universe shook.

Demolishing everyone in his wake, Lesnar forged an impressive undefeated streak, ending legends like Hulk Hogan and winning the 2002 King of the Ring.

Fortunately, there was one man who fans hoped would stop the Next Big Thing, and it was The Rock, who was riding high during his 7th WWE Championship reign.

Meeting at Summerslam, the two young stars waged a war, though it was Brock who came out on top, crushing the People's champion, and their hope.

Winning the title at just 25 years old, Lesnar would continue his dominant ways, holding the title four times, the Universal Championship twice, and is also the 2003 King of the Ring.

Young or old, the Beast Incarnate lives up to his name.
