Surprise Blade (サプライズブレイド Sapuraizu Bureido) is a Double Sword Style: Time Cutter technique used by Fu.
The user charges on the opponent and then buries him with a series of slashes. After that the enemy gets sent in the air with powerful blow and finished with a double slash from powered up sword.
Fu used this technique infused with a Power Ball on Cunber to turn him back to his base form after his Golden Great Ape form was destroying the Prison Planet's Sealing Spell.
