One Piece Ultimate Fight Overview

One Piece Ultimate Fight arrived in 2011 and still plays like a compact arcade duel. Pick your favorite Straw Hat, dive into solo training or local 2-player matches, and string together aerial juggle routes without any downloads. FlashGamesBox hosts the full release online for free, so you only need a browser to start sparring.

Combat Controls and Moveset

• K jumps so you can launch air combos or evade ground pressure.
• D steps right and S drifts left, letting you micro-position around enemy strikes.
• L triggers Soru, propelling you forward to chase or escape at high speed.
• J is your primary attack button for ground strings and aerial finishers.
• U fires ranged specials, while K+J, K+U, S+J, S+U, W+J, and W+U unlock unique combination attacks.
• Tap I when the special gauge is filled to unleash cinematic supers that can swing the match.

Unlocking Post-Timeskip Luffy

Selecting Luffy gives you access to his Post-Timeskip form. Fill the special bar through steady offense, then execute K+J to evolve him mid-battle. The transformation extends combo routes, powers up specials, and rewards players who manage meter and pressure with Gear-inspired finishers.
