Gutiérrez is a third generation professional wrestler, after his father Rey Mysterio and great-uncle Rey Misterio. He has been around wrestling for the majority of his life, thanks to attending WWE events as a child to see his father. He had his first direct involvement when he was 8 years old in 2005, which was a storyline in which his father battled Eddie Guerrero over his legal custody.
He then began training in 2017 and later started appearing with his father on WWE television in 2019. The following year, he began a feud with Seth Rollins, which culminated in his debut match at that year’s SummerSlam in a losing effort. He then formed a tag team with his father in which they won the SmackDown Tag Team Championship once, making them the first father and son team to win a tag team championship in WWE. He later turned on his father in 2022 to join the villainous stable, The Judgment Day, and battled his father in a losing effort at WrestleMania 39.
