Rey Mysterio was always known as a nimble high-flyer during his time with WWE, but since his return in 2018, the former WWE Champion has been heavily praised for his insane body transformation.
Despite turning 47 years of age later this year, Rey Mysterio is producing the best in-ring work of his career at the moment, and a lot of that can be put down to his ridiculous physique transformation.
In the comparison shot below, you can see how much bigger Rey looks now compared to when he first debuted for WWE in 2002 after leaving WCW the year prior.
Despite completely transforming his physique, Rey Mysterio has still been able to impress fans with his jaw-dropping moves in the ring, which only goes further to highlight just how talented he is.
Rey and his son Dominik were drafted over to Monday Night Raw in the WWE Draft last month, with Rey Mysterio being part of the big ladder match with Finn Balor, Kevin Owens and Seth Rollins on last week's show.
Mysterio was also in action on Monday Night Raw this week, losing to former NXT star Austin Theory, albeit only by disqualification.
