6. Ultimó Dragón

When Ultimo Dragon signed with WWE, it was to accomplish two dreams: to wrestle in Madison Square Garden and to be on the card of a WrestleMania. On one hand, Ultimo Dragon did get to do both of these things. On the other hand, it wasn’t the kind of debut he probably had in mind.
Ultimo Dragon was one of ten wrestlers shoehorned into a multi-man elimination match for the WWE Cruiserweight Championship. The match started with two men (one of them being Ultimo) and one by one another wrestler would enter the match after one of the men already in the ring was eliminated.
Dragon’s WrestleMania debut saw him start the match and score a quick pinfall in less than two minutes. However, his contribution to WrestleMania history is more remembered for his entrance botch, as he tripped as he made his way down to the ring.
Keep in mind that Dragon was still a relative newcomer to WWE at the time, and so he had to make an impression on the fans watching WrestleMania. The fact that now most people remember him for this botch as opposed to his actual wrestling tells you how little fanfare there was regarding Ultimo Dragon in WWE.
