Three thousand years ago, the Vader Clan devastated Denji Star. Denjiland, an island from Denji Star, departed from the Denji Star and landed on Earth. In modern times, the Vader Clan was detected approaching Earth, the Denjiland computer awoke the Denjidog IC. It found five young people (who may or may not be descendants of the Denji people) to become the Denjimen in order to defend Earth, the Vader Clan's next target. The Denjimen began a long record of success with the defeat of Vader Monster number 00, Flying Squirreler.
