Addressing the Crossover: Is Goku in That Time I Got Reincarnated as a Slime?

Let's get straight to the point: No, Son Goku, the iconic Saiyan warrior from the Dragon Ball universe, does not appear in That Time I Got Reincarnated as a Slime (also known as Tensura).
It's a common, and completely understandable, point of confusion! With the vast landscape of anime and manga, and the popularity of both these incredible series, it's easy to wonder if characters from different franchises might cross paths. However, Dragon Ball and That Time I Got Reincarnated as a Slime are distinct creations from separate authors, operating within their own unique universes with their own sets of rules and characters. While fan theories and crossover art are always fun to explore, canon material keeps these heroes in their respective worlds.

So, How Old Is Goku Actually? A Chronological Journey Through the Dragon Ball Universe

While Goku isn't busy fighting demons or building nations in the Jura Tempest Federation, his age and physical transformations are a huge part of his own saga! Tracking Goku's age can be surprisingly complex, as the Dragon Ball series spans decades of in-universe time, often featuring significant time skips, deaths, resurrections, and even physical de-aging. We're talking about both his chronological age (how many years have passed since his birth) and his physical age (how old his body appears or functions), which don't always align.
Let's break down the legendary Saiyan's age across his many adventures:

The Beginning of a Legend: Goku's Age in Original Dragon Ball

The journey of Son Goku begins with him as an innocent yet incredibly strong young boy.

  • Early Days: Goku starts the original Dragon Ball series at 12 years old. He maintains this age through the 21st World Martial Arts Tournament.

  • 22nd World Martial Arts Tournament: After a three-year training skip, Goku enters the 22nd World Martial Arts Tournament at 16 years old.
  • 23rd World Martial Arts Tournament & End: Following another three-year time jump, Goku is either 18 or 19 years old by the end of the original series, when he finally marries Chi-Chi.

  • Start of DBZ (Saiyan Saga): Goku is approximately 23 or 24 years old.
  • Frieza Saga: After his initial death and a year of training in the Otherworld, Goku is 25 years old during his legendary battle against Frieza on Namek.
  • Android Saga (Arrival): Two years after Namek, and three years of training for the Androids, Goku is 30 years old at the start of this intense saga.
  • Cell Games Saga: Goku spends one year in the Hyperbolic Time Chamber, pushing his physical age to 31 years old before his sacrifice against Cell. His chronological age is 31, but his physical development reflects this intense training.
  • Buu Saga (Resurrection): After seven years of being deceased, Goku is resurrected. His chronological age is 37 years old, but his physical body remained 31 years old due to his time spent in the Otherworld.
  • End of DBZ (28th World Martial Arts Tournament Epilogue): Ten years pass after the defeat of Buu. Goku's chronological age reaches 47 years old, while his physical body would be around 41-43 years old, factoring in his time alive and dead.
    Understanding reveals how much he matured and developed, both physically and as a warrior.

New Universes, New Powers: Goku's Age in Dragon Ball Super

Dragon Ball Super takes place within the ten-year time skip after the defeat of Majin Buu in Dragon Ball Z, making the timeline a little tricky.

  • Beginning of Super (Battle of Gods Arc): Goku is chronologically 41 years old, but his physical age is closer to 34-35 years old due to the seven years he spent deceased.
  • Resurrection 'F' Arc & Beyond: The series continues, with various short time jumps. Goku trains for three years in the Hyperbolic Time Chamber at one point, further evolving his physical capabilities.
