Though he has never been the tallest wrestler in the ring, Rey Mysterio has had a lot of success in WWE and has become one of the most well-known performers of all-time. That shows you that size does not matter.

Wrestling is a dangerous sport, and for Mysterio, he performed a move that would end up killing someone which caught everyone by surprise.

Rey Mysterio became a star in the world of wrestling

Mysterio is one wrestler that fans know and are always excited to watch him perform. He’s a fearless competitor when he’s out there in the ring, and he doesn’t let his size affect him one bit. Mysterio stands 5-foot-6, and he does not wrestle like he’s that height. The masked star began his professional career in Mexico at the age of 14.

Mysterio made his World Championship Wrestling debut in 1996 and won his first Cruiserweight Championship in July of 1996, which he retained for three months. He always wrestled with his mask on which was part of his identity. Mysterio was known for his acrobatic moves in the ring early on in his professional career. When WCW closed down, Mysterio wrestled independently for a few years.

In July of 2002, he made his WWE debut on an episode of Smackdown! Mysterio battled against some of the top wrestlers in WWE, and he quickly became a fan favorite. He won his first WWE Cruiserweight Championship when he defeated Matt Hardy. During his WWE career, he formed a duo with former WWE star Eddie Guerrero, and the two became favorites across the world. The duo won a Tag Team Championship and would later have a short feud after teaming up together. When Guerrero passed away, Mysterio took it to heart and gave an emotional speech about his good friend Guerrero. During the speech, Mysterio took off his mask and put his head down so no one could see his face.

Rey Mysterio becoming the World Heavyweight Champion

Mysterio got his shot at the World Heavyweight title in 2006 at WrestleMania 22. Mysterio competed in a Triple Threat match between him, Randy Orton, and then-champion Kurt Angle. At WrestleMania, Mysterio pinned Orton to become the new World Heavyweight Champion. Mysterio was able to defend his title a few weeks later, defeating Orton and Angle.

The 5-6 wrestling star continued to fight in the top matches that WWE had to offer. Mysterio was exciting to watch, and fans wanted to see him win. He stepped away from WWE for a little time and wrestled independently and in other wrestling organizations before making a return back to WWE. Mysterio continues to be a part of WWE at the age of 45.

Rey Mysterio’s incident that ended up killing a wrestler

In 2015, Mysterio was wrestling in Mexico during a tag team match. During the match, Mysterio hit Pedro Aguayo Ramirez with a flying kick, one of Mysterio’s most memorable moves. When Mysterio connected with Ramirez, he fell unconscious on the ropes. When it first happened, no one realized how serious Ramirez was injured.

After a few minutes, they realized Ramirez was unconscious and stopped the match. Ramirez died in the hospital the next day. He was the son of a famous Mexican wrestling legend, and his death was a tough pill to swallow for Mysterio and the wrestling community in Mexico. The Baja California state prosecutor’s office said Ramirez died from the blow in the ring, and TMZ reported that the cause of death appeared to be a snapped vertebrae when his head hit the ropes. Mysterio was not charged with anything, and he continued his wrestling career even though the death was hard for him to take.
