Signer Dragon

The Five Dragons are a series of Dragon-Type Synchro Monsters, introduced in Yu-Gi-Oh! 5D's. These legendary dragons play a part in the legend of the Crimson Dragon, as well as being connected to the Signers themselves. That connection being that these legendary beasts who are actually servants to the Crimson Dragon, were the ones who sealed an evilness within the Nazca Lines.

That same evil, which is now known as the Earthbound Immortals, has reappeared once again in the world as Duel Monsters cards used by the Dark Signers.

So far 4 of the Five Dragons have been released in the OCG and TCG: "Stardust Dragon", "Red Dragon Archfiend", "Black Rose Dragon" and "Ancient Fairy Dragon". The supposed mechanical version of the fifth dragon, Power Tool Dragon, was released in Raging Battle. All four dragons have different attributes.

In the anime, Professor Fudo gave the "Stardust Dragon", "Red Dragon Archfiend", and "Black Rose Dragon" Duel Monsters cards to Rex Goodwin. As these three, along with the "Ancient Fairy Dragon" card were originally designed so that their corresponding Signer could activate the safety switches for the Old Enerdy system.

Each of the revealed four dragons has at least one special support card -- Stardust Dragon has Stardust Xiaolong, Stardust Flash, Stardust Mirage, Starlight Road, and Shooting Star; Red Dragon Archfiend has Crimson Fire; Black Rose Dragon has Thorn of Malice; and Ancient Fairy Dragon has Ancient Sunshine and Regulus.

Members
With the exception of the Fifth Dragon, who hasn't appeared as a card at all, the Signers possess the card forms of their respective Dragons.

Assault Modes
"Stardust Dragon" and "Red Dragon Archfiend" have their own "/Assault Modes": "Stardust Dragon/Assault Mode" and "Red Dragon Archfiend/Assault Mode". Both of them were Summoned by Yusei and Jack in a special episode.

Example:



Majestic Forms
The Majestic Dragons are upgraded forms of the Five Dragons, similar to the /Assault Mode monsters, summoned by Tuning Majestic Dragon with one of the Five Dragons and 1 non-Tuner Monster. They tend to have multiple powerful effects, currently being the strongest of all Synchro Monsters, but are balanced out by returning themselves to the Extra Deck during the End Phase while reviving their previous form from the Graveyard.

So far, only 2 have been revealed: Majestic Star Dragon and Majestic Red Dragon, which were both used in the anime by Yusei Fudo and Jack Atlas, respectively.
