|This article is about a/an monster in Hyakujuu Sentai Gaoranger.|
The result of an Org Spirit entering barbed wire, Barbwire Org terrorized people until the Dukes Orgs found him, offering him aid in his destructive urges. Kakeru attempted to try a less violent-method to deal with the Org, only to learn that Orgs have no hearts. Barbwire overpowered the Gaoranger until they use Hyakujuuken to kill him. But he was quickly revived by TsueTsue into a giant and is the first to be killed by GaoKing's Animal Heart.
