Naruto wins this matchup at peak power. Baryon Mode operates at a scale above Gear 5 Luffy in raw destructive power. But Gear 5 unpredictability makes it genuinely competitive.

Naruto at Peak

Baryon Mode passively drains the life force of anyone Naruto contacts. Six Paths Sage Mode allows mountain-splitting casual attacks. Truth-Seeking Orbs nullify ninjutsu and destroy matter at the molecular level.

Luffy at Peak (Gear 5)

Gear 5 operates on cartoonish reality-warping — Luffy can turn the environment into rubber, laugh power into attacks, and heal instantly. Bajrang Gun is country-devastating in scale.

Verdict

Peak Naruto (Baryon Mode) likely wins on raw power and speed. But Gear 5 Luffy introduces reality-altering unpredictability that makes this genuinely competitive — one of the most debated shonen matchups.
