|This article is about a/an race of monsters in Kamen Rider Kiva.|
The Frankens (フランケン族 Furanken-zoku) are a race based off Frankenstein's Monster. Like the Wolfen and the Mermen, the Franken are nearly extinct and their only survivor, Riki is in service to Kamen Rider Kiva.
The Franken are physically one of the the strongest of the Demon Races possessing unbeatable strength. Like some other Demon Races, the Franken can feed off souls. They do this by grabbing a person and draining the soul out through an electric charge. They are able to assist Kiva Riders by adding a portion of their powers while also becoming a part of their armor and weapon.
