Blaze from Sonic most closely resembles Pyra/Mythra in Super Smash Bros. Ultimate, with Pyra being the closer single match because of the fire theme and powerful, graceful attack style.

Why Pyra fits best

Blaze and Pyra both center on fire-based offense, strong aerial presence, and a “powerful but elegant” feel rather than brute-force brawling. If you’re thinking about overall vibe, Blaze also lines up with characters who feel fast, controlled, and a little regal in animation and posture.

Other close matches

  • Ike : similar in the sense of disciplined, heavy-hitting sword pressure, though he lacks the fire-and-speed identity Blaze has.
  • Roy : has fire visuals and a quicker, flashier feel, but he is much more sword-focused than Blaze.
  • Pyra/Mythra : the best overall comparison because Pyra covers the fire side while Mythra covers the agile, refined side.

Most likely answer

If you want one fighter, pick Pyra. If you want the closest overall Smash Ultimate pairing, Pyra/Mythra is the strongest match.

Blaze’s closest Smash equivalent is basically “a fire-powered, elegant bruiser,” and that points most directly to Pyra.

TL;DR: Pyra is the closest single Smash Ultimate fighter to Blaze, while Pyra/Mythra is the best full comparison.
