WrestleMania is the Showcase of the Immortals, a place where stars are made and legacies are created. If you’re going to be anyone in WWE, you have to perform at WrestleMania. So, it’s actually funny when you find out that so many of WWE’s top stars actually had pretty mediocre outings their first time on the Grandest Stage Of Them All. It turns out, for every Brock Lesnar or John Cena winning titles at their first Mania appearance, you have a laundry list of Legends who toiled away in meaningless undercard matches that nobody remembers. Some of them even lost! You could actually fill a Hall of Fame (and in the case of most of this list, WWE already has) with the wrestlers whose WrestleMania debuts have been fairly forgettable. You might think we’re exaggerating, but take a look at some of the examples we found.
10. Rey Mysterio, WrestleMania XIX
When he debuted in 2002, Rey Mysterio was seen as one of WWE’s biggest signings since buying WCW, and a sign that WWE might actually have finally decided to try and replicate their former competitor’s success with a Cruiserweight division. Fast-forward to WrestleMania, and Rey Mysterio loses his WrestleMania debut in a match for the Cruiserweight title against Matt Hardy Version 1.0, who although entertaining in that persona, was nowhere near the appropriate weight limit to be considered a Cruiserweight (granted, WWE pretended he had lost a bunch of weight as part of a somewhat funny storyline, but there’s no way Hardy could be considered in the same group as “real” Cruiserweights, and he would have been just as entertaining fighting in his regular weight class). It’s actually kind of funny that Mysterio, who was such a big deal and was clearly expected to spearhead the Curiserweight division, and who had already won the WWE Tag Team Titles as part of the far-too-brief “Smackdown Six” era, would actually end up losing his first shot at the Cruiserweight title in WWE at WrestleMania, when many assumed he should have won.
