#2 Heath Slater
WWE always provides the fans comic relief during the 30-man match which almost lasts an hour. In the 2018 edition of the Royal Rumble PPV, we saw Heath Slater perform this role when he spent almost 10 minutes outside the ring after entering the match.
Slater was beaten up by every superstar who entered the match after him, and the fans enjoyed every moment. Heath Slater later entered the ring and even eliminated 'the Celtic Warrior' Sheamus from the match.
Slater is a former SD Live tag team champion, and he has been with the WWE for quite a while now. Vince McMahon has promised Heath Slater that 2019 will be his year in the WWE, so there is no shadow of doubt we will see Heath Slater in the 30-man match once again in the year 2019.
