How to say "invincible" in Japanese

• 無敵むてきCommon
  no-adjective, na-adjectiveThe broadest of the three: 'invincible' as simply unbeatable, extending to 'unrivaled, matchless.' Natural for a fighter, team, or anything that cannot be beaten.
• 常勝じょうしょうCommon
  no-adjective, suru verb, intransitive verbFrames 'invincible' as ever-victorious: the emphasis is on winning every time, an unbroken string of victories. Suits a team or army that keeps on winning.
• 不敗ふはいCommon
  no-adjectiveCenters on never having been defeated: the point is a spotless record with no losses. Especially apt when 'invincible' really means 'undefeated,' as of a champion who has never lost.

Choose 無敵 for the general sense of unbeatable or matchless; use 常勝 for the ever-victorious nuance of winning every time, and 不敗 when the sense is undefeated, with no losses on record.
