#1 Bring Back: The Rock

Don't get me wrong, I'm not saying he should come back full-time, but a brief return by the Great One would be amazing to see.
Rock's last match took place in 2016, lasting a matter of seconds, with his last competitive match being in 2013.

A former World Champion, The Rock could even go toe-to-toe with Lesnar over the Universal Title, in what would be a rematch of their epic Summerslam 2002 encounter.
Imagine how incredible it would be to see the Brahma Bull have a match on RAW, over a decade after his last one.
Even if he was to come back for a few months, it would be exciting to see the Most Electrifying Man in Sports Entertainment back, and could lead to some iconic moments in 2019.
