2. Rene Dupree - WWE Smackdown vs. Raw (20 years, 10 months and 19 days old)
When Rene Dupree joined the WWE in 2003, he became the youngest Superstar ever to become a champion.
Capturing the World Tag Team Championships with Sylvan Grenier, the pair defeated teams like the Dudley Boyz and Scott Steiner & Test, holding the gold until Unforgiven 2003.
The group only became more powerful when French sympathizer Rob Conway joined the group.
Appearing in the first SmackDown Vs RAW in the fall of 2004, Dupree became at the time, the youngest Superstar ever to be included in a WWE Video Game, as well as the youngest champion
With a solid 83 rating, Dupree was a decent all-rounder in the game, though with never having a face run in the company, probably wasn't many fans first picks when they got the game in November 2004.
