Goku's status as immortal in Dragon Ball GT is a complex issue; while he doesn't become completely invulnerable, he demonstrates agelessness, suggesting a form of immortality, particularly by the end of the series.
Here's a breakdown:
-
Agelessness: In Dragon Ball GT: Hero's Legacy, set 100 years after the end of GT, Goku appears as a young man, implying that he no longer ages. This is the primary evidence supporting his immortality.
-
Not Invincible: It is crucial to note that agelessness doesn't equate to invincibility. He can still be harmed and, potentially, defeated, though this is never shown. His immortality is more akin to eternal youth rather than complete immunity to death.
-
Relationship with Shenron: The circumstances surrounding Goku's departure with Shenron at the end of GT are ambiguous. It's implied he takes on a divine role, protecting the universe, which further supports the idea that he exists outside the normal constraints of life and death. This is not explicitly stated, but strongly suggested.
-
Comparison to Previous Near-Death Experiences: Throughout Dragon Ball, Goku has repeatedly pushed past his limits and survived situations that should have been fatal. However, these events do not directly translate into immortality. GT presents a different scenario, wherein his very nature seems to have changed.
Therefore, while Goku isn't invulnerable in GT, he appears to possess agelessness, which could be considered a form of immortality. It's more accurate to say he has eternal youth and seemingly cannot die of old age, but he is not impervious to all forms of harm.
