Batista: I'm Not Who I Am Today Without The Moment Of Winning The WWE Title At WrestleMania 21

Batista (Dave Bautista) captured his first WWE Championship at WrestleMania 21 when he defeated Triple H in the main event of the show.

Celebrating his 54th birthday on January 18, Batista took to Instagram to re-watch the end of his WrestleMania 21 match and explain how it helped get him to where he is today.

"WrestleMania 21, this is the end of the match and I can't believe this is happening at this point. I can't believe this. This happened so fast where I went from being a guy in the background that they never had any big plans for to being the top guy in the company to now I'm the flagship, I'm the guy holding the belt. A lot of responsibility comes with that. I was so unprepared. I was not prepared for what was coming my way. Triple H was my mentor, he groomed me as best he could up until then. It just came to a point where I was on top now and I had to come into my own. It was still a lot of learning lessons after this. I was thrown into the deep end. I didn't plan on this. Watching it makes me emotional. I just never planned for this. When I was wrestling, I was just happy to have a job and always thinking that I was going to lose my job any day. Becoming World Champion was something I never imagined. They always say, 'Why do you want to be there if you don't want to be champion?' I was content just having a job. I just wanted to make a living, being able to support my family. Being champion and being on top of the company was something that was beyond my dreams. With me, it's always baby steps. I find things by accident, almost, and then I chase them once I find out that I really love something. I put everything I have into it, I put blinders on, and sometimes that's been a fault. I've sacrificed some things because of that, but my life is what it is because of that. This is still surreal, watching it," he said.

Batista wrestled his last match at WrestleMania 35, losing to Triple H.

Since wrapping up his full-time career in wrestling, he has gone on to have a successful Hollywood career, starring in films such as "Guardians of the Galaxy," "Avengers: Endgame," "Dune," "Glass Onion: A Knives Out Mystery," and more.

Filmmaker Rian Johnson called Batista the best wrestler turned actor ever.
