Blue Forte Wave (ブルーフォルテウェイブ Burū Forute Ueibu?) is the purification attack that Cure Marine can use in Heartcatch Pretty Cure!. It is one of the ways to purify a Desertrian, so it is considered a finishing move. The move can only be used by Cure Marine, but there are four attacks similar to it, Pink Forte Wave, Silver Forte Wave, Dark Forte Wave, and Gold Forte Burst.
Cure Marine summons her Marine Tact, she then spins the center of the tact, and rainbow lights go into the gemstone tip of the tact. The tips surge with purity energy, and Cure Marine spins before declaring the attack name. She then shoots out an energy flower at the Desertrian. An implosion occurs, and the target is suspended in the air, a cyclamen having overlapped behind it. Cure Marine claps the center of the Marine Tact to keep the center spinning, and in a flash of light, the enemy is purified.
