Rat Fangire

Rat Fangire (ラットファンガイア): The Rat Fangire is a speed fighter who uses pistols or swords as weapons. Appearing in 1986, he is first targeted by Yuri Aso until he attempts to kill her. When Maya interferes and intentionally tries to kill him, the Rat Fangire sought revenge on any Fangire entitled the Queen of the Checkmate Four.

By 2008, the Rat Fangire developed the ability to multiply himself, overwhelming opponents with an army of clones until they are all shattered by Kiva Emperor Form with the Zanvat Sword in hand.
