The Rock’s Brahma Bull tattoo on his right arm is as much a part of his electrifying persona as The People’s Eyebrow, but that isn’t stopping him from bringing about the “evolution of the bull” with the help of tattoo artist Nikko Hurtado.

“I got this tattoo when I was just a kid. Now I need it to reflect me as a man,” The Rock wrote on Instagram.

See The People’s Champ begin the process of “evolution” in the video below, and look below for the finished image.

Evolution of the bull. After 3 sessions and 22hrs of tattooing with world renowned @NikkoHurtado, the story's almost done.. Every detail is a reflection of my own personal history. From the cracks and heavy damage in the bone representing life's hard lessons I've learned over the years. Just like scars and wrinkles - I'm so grateful to have 'em because they're earned. To the horns, not pointing up or out to the side, but pointing straight ahead representing relentless energy and forward progress. The core and anchor of this image is in the eye. Look closely and you'll find the life, energy, power and you'll feel the MANA (spirit). The eye tells the story of a disruptive positive energy always ready to dent the universe. Depending on the light and angle, sometimes the energy's subtle and sometimes it's glaring. But it's always alive and ready to disrupt the universe and love and protect my family and all things I love with intense passion and gratitude. Cheers to living, learning, evolving and growing. And to the positive disrupters ready to dent the universe. #EvolutionOfTheBull #TheDisrupter #TheMana #NowLetsBreakOutTheTequila
