Blaze the Cat is generally listed as 14 years old in official-style character profiles for the Sonic series.

Quick Scoop: Blaze the Cat’s Age

  • Blaze the Cat is a fictional character from Sega’s Sonic the Hedgehog franchise.
  • Fan-maintained databases and character wikis consistently list her age as 14 years old.
  • These ages are “in-universe” character ages, not tied to real-world time passing since her debut in 2005’s Sonic Rush.

So even though Sonic Rush came out years ago, Blaze herself is still treated as a 14-year-old in the current franchise context.

TL;DR: Blaze the Cat’s canonical character age is 14 years old.
