Thragg doesn’t have an exact “birth year” stated in Invincible canon, but he is explicitly described as being thousands of years old and older than Omni-Man, who himself is over two millennia old.

How old is Thragg?

  • The Invincible lore states that Thragg fought in the Viltrumite civil war right after Emperor Argall’s death, an event that took place thousands of years before the main story.
  • Official-style writeups and character bios emphasize that this means Thragg is “thousands of years old,” not just a few centuries.
  • Fans on forums commonly estimate his age in the range of around 2,000–3,000+ years, often putting him older than Omni-Man, who is already over 2,000 years old.

So, in universe terms: Thragg is an ancient Viltrumite, several thousand years old , still in his physical prime thanks to Viltrumites’ extremely slowed aging.

Why his exact age is fuzzy

  • Viltrumites age slower the older they get, so their apparent age doesn’t map cleanly to human years.
  • The comics and related material focus more on his role in ancient Viltrumite history than on giving a precise numeric age.
  • Community discussions treat any specific number as an educated guess rather than confirmed canon.

Quick forum-style take

If you’re just looking for a quick answer to “how old is Thragg”:
He’s at least a couple of thousand years old , likely somewhere in the low several-thousand range, and canonically “thousands of years old,” older than Omni-Man.

TL;DR: Thragg’s exact age isn’t given, but canon makes it clear he’s thousands of years old and older than Omni-Man, who’s already over 2,000.
