Life Stream Dragon (character)

The Fifth Dragon is one of the mysterious creatures who is a member of the Five Dragons.

Its whereabouts are currently unknown. No Signer has been shown to possess it yet, making it the only one of the Five Dragons to have not appeared as a Duel Monsters card to date.

"Power Tool Dragon", which belongs to Leo, looks like a mechanized version of the fifth dragon. Leo mistakenly believed "Power Tool Dragon" to be the fifth dragon and believed himself to be the fifth Signer after asking Luna if "Power Tool Dragon" took part in the ancient battle between the Five Dragons and the Earthbound Immortals. Luna replied that maybe it did, just to make him happy, although she didn't think it was the same dragon, since such a high-tech robotic dragon couldn't have taken part in the ancient battle.

It also appears in in the Japanese Yu-Gi-Oh! 5D's opening theme "BELIEVE IN NEXUS" and the ending themes "CROSS GAME" and "Close to you".
