#2 Rene Dupree - WWE World Tag Team Champion aged 19
Rene Dupree was still a teenager when he made his WWE debut on RAW as one half of La Resistance, paired with Sylvain Grenier in 2003. The pair attacked Scott Steiner on their first appearance on the red brand, establishing a feud with him and Test.
On their first pay-per-view match, La Resistance defeated Steiner and Test at Judgement Day. They later moved into a rivalry with Kane and Rob Van Dam, who they beat at Bad Blood to become the WWE World Tag Team Championship holders.
This title win made Rene Dupree the youngest-ever championship winner in WWE at the time. He was aged 19 years and six months when he lifted the championship with Sylvian Grenier at his side. He was also the first-ever teenager to win a WWE title.
La Resistance remained WWE World Tag Team Champions for 98 days, until they were dethroned by The Dudley Boyz at Unforgiven in September 2003.
Rene Dupree would become a two-time champion in WWE at the age of 20, when he won the WWE Tag Team Championships paired with Kenzo Suzuki on SmackDown a year later.
