#4 Jinder Mahal
The Modern-Day Maharaja was once nothing but an enhancement talent, who used to lose matches right and left on WWE Main Event, alongside Drew McIntyre and Heath Slater. After splitting with WWE in 2014, Mahal worked on his skills as well as his look. He worked on the independent scene for around two years, before returning to WWE. Mahal was pushed heavily around a year after he returned. He defeated veteran Randy Orton to become the 50th WWE Champion at Backlash 2017, in one of the biggest surprises in WWE history.
Mahal never achieved the same feat again, but there's no telling what can happen now that he will be under the WWE umbrella till 2024. Back in June 2019, it was reported that Mahal had signed a 5-year deal with WWE. After being on the sideline for months due to an injury, Mahal returned to RAW soon after WrestleMania 36, defeating Akira Tozawa in the process. Only time will tell how WWE utilizes Mahal over the next four years or so.
