Wavesurfer (ウェブサーファー, Webusāfā?) is a technique appearing in Kingdom Hearts 3D: Dream Drop Distance. It allows the user to use their Keyblade as a surfboard, and attack enemies within range.
Wavesurfer is a Single Link used by Riku. While activated, Riku turn his Keyblade into a blue surfboard surrounded by water, which he rides on, dealing water attacks while riding it.
When using Wavesurfer, Riku gains a dark blue aura around him. Particles of water emit from his body as well.
