[Kamen Rider Exile]

Kamen Rider Kabuto why?

As Tendou says henshin, the deep driver voice repeats "henshin". Like Kiwami stated, the hexagons form as he walks slowly, with the charging sound. In most episodes, you can feel the tension rise or the music stop when he's finally done playing and says "Cast off". The belt then does this ticker sound as each individual pieces lift off, and in the last shots before you see the armor flying, you get a glimpse of Kabuto's face. As the armor flies off, everyone ducts then looks up to the horn rising up to Tendou's face. Finally after the horn slowly lands on his face, completing the transformation, Kabuto's eyes light up as the driver states: "Change Beetle" with an emphasis on BEEtle.

The most recognizable example of this is during the first all out battle in GSL.
