|Kamen Rider Strong Demon|
Ken Fletcher briefly transformed into what was called Transformed Ken by the Echo Demon production crew. In the movies, this form is dubbed Kamen Rider Strong Demon. Ken only transformed in the final episode of Kamen Rider Echo Demon.
Ken Fletcher is a young man attending the same school as Josh Morrow & Diana Fairchild. He appears in the second half of the series wanting to be a Demon. Ken is very strict & competitive, often correcting others of small mistakes (e.g. Josh's notes) & getting himself & others in competitions that they don't want to do.
His reason for wanting to become a Demon was because of his estranged father. Only seeing what his father did in life, Ken saw becoming a Demon as his chance to be greater than his father. Ken pursued Hibiki, aiming to become his disciple. Hibiki saw Ken's reason as selfish & refused to let him become his student but Ken was adamant. Later, he formed a partnership with Josh & pledged Hibiki to become his students.
After Diana persuaded Hibiki to let Josh & Ken become his students, he took them under his wing. However, Ken struggled in nearly every training session, unlike Josh, which shows that Ken isn't very athletic. During the Dragon Sealing, Ken aided Hibiki when the latter dropped his drumsticks. A year later, he is still apprenticed to Hibiki but is already allowed to transform. He fought the Makamou who kidnapped a friend of Josh's in that form but was almost defeated until Ibuki & Todoroki came.
