Has Anyone Beaten Wii Punch-Out!! Completely? Yes – Many Have

Yes—many players have. "Beating" can mean:

• Campaign clear: Defeat Mr. Sandman (Title Defense) → credits. Thousands have done this.
• All challenges: Complete every Mac's Last Stand / Exhibition / Champion Mode challenge.
• Speedruns: Any% ~22 min, 100% ~2h. World records on speedrun.com.
• No-damage / One-punch / Blindfolded runs: Community showcases extreme mastery.

Why No "Official" Record

• No central leaderboard for "100% completion."
• Wii Friend Code era—no unified tracking.
• But speedrun.com, YouTube, Discord communities document countless completions.

Notable Feats

• Sinister1 / Punchy / other top runners – frame-perfect dodges, star-punch optimization.
• Mac's Last Stand (post-game) – 13 fights, no continues, brutal RNG.

If you mean "has any human ever finished it?"—absolutely. It's hard but fair. Practice patterns, learn tells, earn the championship belt.
