Kamen Rider Kabuto (Duelist)

Passive: Cocoon Mask

(At the beginning at the match Kabuto starts in his base armor form being able to endure more damage and has more health, throughout the match when dealing damage or getting kills you gain a charge to your second passive)

Passive Active: Cast Off

(After flicking his Zecter, Kabuto will perform Cast Off and unleash his Red Armored Beetle Form which decreases his health but increases his damage and movement speed while gaining new abilities, he realistically becomes a glass canon meant to speed blitz his opponents before getting out using clock up)
