#4 Baron Corbin (WWE WrestleMania 32)
Baron Corbin made his WWE main roster debut in an exceptional way. After an impressive run in WWE NXT, Corbin debuted as a surprise entrant in The Andre The Giant Memorial Battle Royal at WrestleMania 32 in 2016. But Corbin wasn't the only surprise entrant in the match.
Legendary WWE Superstars such as Diamond Dallas Page and Tatanka were joined by NBA icon Shaquille O'Neal as entrants in the match, much to the surprise of the WWE Universe.

After the giant figures of The Big Show and Shaq were eliminated by other participants, the field was eventually whittled down to Baron Corbin and Kane as the final WWE Superstars standing.
After a significant amount of back and forth action, The Lone Wolf eliminated The Big Red Machine to win the Andre The Giant Memorial Battle royal on his main roster debut. This was an incredibly impressive victory for the former NXT star.
No other NXT star had made their main roster debut at WrestleMania in the past, let alone won a major match such as the Andre The Giant Memorial Battle Royal.
