Roger Backus

Kamen Rider Roaring Demon is one of the many Oni Kamen Riders in the fanfictional series Kamen Rider: Echo Demon.

Roger/Todoroki
Roger (who is referred to his Oni name, Todoroki) is the young brother of Vega & the last Oni to join the main Riders.

Of the three four Oni, Roger is the second oldest, yet he is the most childish. He still acts like a novice with many Oni matters & enjoys the simple things that life has to offer him. He is also one of the more clumsy characters on the show, this trait often leads to problems both in & out of battle. Even though often misguided, Roger will stand by his friends no matter what comes their way.

Bio
Ability Perimeters: In this form, Roaring Demon is a green demon. This is his basic form & the easiest form for him to reach. To become this form, Roaring Demon simply needs to pluck his brace strings, the vibrations from the strings cause his body to be hit by massive lightning bolts, changing him into his Oni form. Roaring Demon also gains a second "oni face" which is a crest that forms on his forehead. Unlike most Kamen Riders, Roaring Demon does not wear a suit, rather his demon form is his true form.

Transformation Demon Chord - Lock String
Unlike the other Oni's transformation items carried on their belt, this is worn on Roaring Demon's left arm like a bracelet. The Transformation Demon Chord - Lock String is worn on the wrist, plucking the small chords sends out special sound waves which gives Roaring Demon the ability to transform into an Oni. After plucking the cords he places it in front of his forehead forming an Oni face. He raises his arm into the air as lightning strikes him with electricity surrounding him while he transforms. In addition, the Lock String can also playback the sound or video data collected by the Disc Animals.
