Beginning with Gear 4, OPTS has introduced Mode Change Specials. These Special skill card will activate Mode Change for a limited time in battle, which:

  1. Changes the appearance of the character
  2. Changes the skills equipped on the character
  3. Changes the auto-skill of the character

For Luffy’s Gear 4, for example, his auto-skill becomes: increases own physical attack, reduces physical damage received, and become harder to knock back.


Gomu Gomu no Kingkong Gun can only be used in Boundman Mode Change. Hits the ground with a giant fist. Physical damage.
