#3. Former WWE Champion Jeff Hardy
Jeff Hardy made his original WWE debut when he was just 16 years old, after lying to the company and claiming he was 18.
For almost three decades, Hardy has had several stints in WWE as well as on the Independent circuit. The fact that Hardy debuted in WWE when he was just a teenager and a jobber means that he has gone through many changes over the years.

The above image shows that when Hardy made his debut in a match against Razor Ramon on live TV, he was much smaller and had not been able to grow his hair out.
Hardy debuted in standard wrestling gear and has since been able to become recognizable for his darker ring attire as well as his long hair. This was also many years before Hardy began making face paint a main part of his character.
Hardy is nearing the end of his wrestling career now after almost 30 years in the spotlight. The images above show that the former WWE Champion has obviously gone through several changes throughout his career.
