―Transformation phrase[src]

"You think you can beat us alone? That make me upset."
―Fu's response to the Owl Hazard Smash challenging him and his brother.[src]

"We're the ultimate weapon of Namba Heavy Industries Ltd., how could we become a scrap so easily?"
―Fu reveal the Kaisers' origin to Ryuga.[src]

"Fighting for someone's sake...wasn't bad after all... I should tell this... to my brother..."
―Fu's last words to Ryuga[src]

Fu Washio (鷲尾 風 Washio Fū) was the older brother of Rai Washio, one of Namba's children hailing from Seito. He is able to transform into the turquoise Kaiser, Remocon Bro's (リモコンブロス Rimokon Burosu).

Character History

Little is known about Fu's past, but he and his brother were raised by Juzaburo Namba’s institute as his 'Children'. There, Fu and Rai were indoctrinated and trained as soldiers.

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 Bro's easily and taunt Grease to become Seito weapon, if he wants Kiba to live.

After they torture Kiba, Kazumi and Akaba arrive and Kazumi rejects Rai offer and fights him as Grease. Grease, along with Akaba and Kiba escapes, but later shot by Fu using Nebulasteam Rifle. Fu's about to kill Grease, if Kiba didn't take the bullet for him. Akaba later helps his boss escape once more, to Sky Road where Sento and Banjo await.

As the Washio brothers finally caught up to them, Sento and Ryuga fight them as Build Rabbit Tank Hazard (later Rabbit Tank Sparkling) and Cross-Z Charge respectively, until Rogue makes his appearance. The Phantom of the West

Joining Seito's forces in an attack on the Touto government office, the Washio brothers covered Rogue as he went in to claim the Pandora Box, engaging Kamen Riders, Cross-Z Charge, Grease and Build before the latter caught up with Rogue. Eventually, the Kaisers succeeded in defeating the Sclashjelly Kamen Riders. A Man Called Rogue

Alongside Rogue, the Washio brothers represented Seito in a three-stage Proxy Battle with Touto. With Rai having been defeated by Grease in the first round, Fu used his Gear Engine along with his own Gear Remocon to transform into the Hell Bro's as he faced Cross-Z Charge in the second round. The Treacherous Deathmatch Though surprised to find his greater power matched by Cross-Z Charge as his opponent grew continually stronger, Fu was able to goad Ryuga into letting his guard down by claiming that his brother had been taken to custody and scheduled to be terminated should he fail. Fu used Ryuga's hesitation to knock him out of the battle, after which Rai appeared unharmed to gloat with his brother. The Counterattack Hero

Death

After Evolto declares that he will rule the world, Utsumi decides to strengthen the Washio Brothers by injecting them with Nebula Gases. However, even with the conditioning and temporary alliance with Touto Kamen Riders, Evol Black Hole is still too much for them to handle.

After Evol kills Rai with a Miniature Black Hole, a grief-stricken and enraged Fu transformed into Hell Bro's and fights Evol head on. However, Evol manages to defeat him and Cross-Z Magma, whose transformation is cancelled as result. As Evol is about to kill Banjo using the Black Hole Finish, Fu, who had a change of heart after seeing Banjo indirectly fighting for them decides to save Banjo, while taking the bullet from Evolto. Banjo Ryuga, who was confused and worried asks him why Fu saves him. Fu replied by saying that fighting for other people isn't bad, and that he will teach this to his brotherMad World

Personality

Compared to his brother, Fu is more calm and collected. He rarely speaks, unless when needed. He also prone to making lies, as shown when he told Banjo that if he loses, Rai will be killed. After he defeats Banjo, he shows no remorse and calls him scrap for being too gullible. Both Fu and Rai are cruel and ruthless, and like to torture their defeated opponents.
