Fu Washio (鷲尾 風) is the older brother of Rai Washio, hailing from Seito. He is able to transform into the turquoise Kaiser, Remocon Bros (リモコンブロス).

Character History
Fu, along with Rai was first shown at Hokuto after Kiba defeats Seito Guardians as Owl Hazard Smash. They quickly defeat the latter as Engine and Remocon Bros easily and taunt Grease to become Seito weapon, if he wants Kiba to live.

After they torture Kiba, Kazumi and Akaba arrives and Kazumi rejects Rai offer and fight him as Grease. Grease, along with Akaba and Kiba escapes, but later shot by Fu using Nebula Steam Rifle. Fu's about to kill Grease, if Kiba didn't took the bullet for him. Akaba later helps his boss escape once more, to Sky Road where Sento and Banjou awaits.

As Washio brother finally caught up to them, Sento and Ryuga fights them as Build Rabbit Tank Hazard (later Rabbit Tank Sparkling) and Cross-Z Charge respectively, until Rogue make his appearance.
