The Transformation Cell Phone ShodoPhone (変身携帯ショドウフォン Henshin Keitai Shodō Fon) is the transformation device that Lord Takeru Shiba and his four retainers use to change into the Shinkenger team. In order to become Shinkenger, they must change from Cellphone Mode (携帯モード Keitai Mōdo) to Brush Mode (筆モード Fude Mōdo), inscribe their kanji in the air, and press the blue henshin/call-answer button, to activate the transformation by shouting "Shodophone! One Stroke, Imperial Report!" (「ショドウフォン！一筆奏上！」 "Shodofon! Ippitsu Sōjō!")
The brush mode allows for much more than transformation, however. The right kanji (provided that it is written in the correct stroke-order) can do whatever its meaning indicates. During their samurai training, the four retainers are seen practicing their calligraphy, summoning up winds, leaves, and waves of water. In battle, the brush mode can be used as an improvisational weapon, used to summon forth anything the Shinkenger may need to combat the Gedoshu. It can also be used to enlarge their Origami, by inscribing the "Big"(大) kanji on it.
At the climax of the Great Legend War, the ShodoPhones as transformation devices were made redundant when the Shinkengers sacrificed their powers with the rest of the first 34 Super Sentai to destroy the invasion force of the . Resurfacing as Ranger Keys, the Shinkenger powers would be used by the to assume their forms via the Gokai Change. Ultimately, the Gokaigers returned their borrowed powers to their rightful owners after overthrowing Zangyack.
