Brock Lesnar was 25 years, 1 month, 13 days old when he defeated The Rock for the WWE Championship in August 2002. It was the main event of SummerSlam and Lesnar had only been on the main roster for five months. It still stands as a stunning testament to how clearly Lesnar had "it" as a star. He was barely even with the company and he was already champion. He was still a youth in many ways, but he'd already grabbed the number one spot in wrestling. Randy Orton was younger when he won the World Title at SummerSlam 2004, but Lesnar's record with the WWE Title is still standing and unlikely to be broken any time soon. At 25 years old, he is the youngest WWE Champion ever. More than a decade later and he's still kicking a** in the main event spots.
