#4 Fénix and Pentagon Jr. (Impact to WWE)
Fenix and Pentagon Jr. are considered to be one of the best and most successful Lucha Superstars ever. They have also worked in Lucha Underground and MLW and were also featured in the All In PPV.
Both men were rumored to be on WWE's radar for a long time but as reported their contract with Impact Wrestling will run out in 2020, which rules out all the possibilities of seeing these two talented Lluchadors in WWE ring anytime soon.
But, luckily we can expect WWE to offer them a contract and sign them up as soon as they are done with Impact. And who knows when they will make their debut in WWE, they might form a stable of luchadors including Rey Mysterio, who is already scheduled to appear on SmackDown 1000.
