#2. Mansoor
Mansoor may not have really debuted on the main roster as of yet, and he may not be that prevalent in NXT, either. But, Mansoor does have the undeniable record of being undefeated on Saudi Arabian soil.
Firstly, he claimed a stunning victory against 50 other main roster superstars to win the Battle Royale at WWE Super Show-Down all the way back in June 2019. Then, perhaps unsurprisingly given he'd just toppled 50 Superstars in one go, he got an impressive singles win against Cesaro at WWE Crown Jewel 2019.
These two victories make Mansoor undefeated at WWE PPVs in 2019 which is a feat that only The Fiend/Bray Wyatt and the last name on this list can also claim, so he's in quite the esteemed company.
I fear that Mansoor might not retain his undefeated streak were he to wrestle outside of the main roster as he's certainly not undefeated in NXT (at all). But, if he only wrestles in Saudi Arabia, he might surpass this next guy one day.
