Kamen Rider Garren first appeared in Kamen Rider Blade, the 2004 Heisei era tokusatsu series from Toei. He is the alter ego of Sakuya Tachibana, a member of BOARD who fights the Undead using the Rider System and Rouze Cards. Like other Riders in the franchise, his henshin call marks the change from human to armored fighter. Clips of these transformation sounds circulate widely among tokusatsu fans online, shared for edits, ringtones and nostalgic posts celebrating Blade and its distinctive card-based battle system.
