One of the Riders in Kamen Rider Blade. Garren is patterned after a stag beetle and the suit of Diamonds. Its human form is a man named Tachibana Sakuya.
Garren is an integral part of the "ondul" memes, as his distant, cold stare elicits the infamous "オンドゥルルラギッタンディスカ!" (a horribly botched attempt at "Hontou ni uragittan desu ka?", or "Are you really betraying us?") from Blade.
