Useable Skill

Hado Kaio's default Skill Arm comes with the Useable Skill called 'Blow Away" (フットバス, Fūtobasu?) which allows you to freely move the Bakugan to any Gate Card being occupied by an opponent's Bakugan to trigger a Power Battle.


'Hado' is derived from the Japanese for surge, 波動 (hadou). 'Kaio' is derived from the Japanese for the king of sea, 海王 (kaiō).


  • Hado Kaio was once named Water Dragon (水龍, Suiryū?) tentatively.[1] 
  • Hado Kaio resembles Saint Aquas.
  • The Hado Sole Parts is of the same mold as the Rekka Sole Parts.
