A '''Mark Five thousand years before the present-day events of the Dragon''', known as a 'Yu-Gi-Oh! 5D's'Dragon Birthmark''' (竜の痣 ''Ryuu no Aza'') in the Japanese version, is a special mark that indicates that a person is a [[Signer]]. The symbol of the dragon is the Ouroboros, which is either a dragon, a lizard or a serpent biting its own tail. The symbol represents unity, infinity or a never ending cycle. Five thousand years ago, an ancient civilization known as the People of the Stars worshiped a mystical light called the [[Dragon Star]], which was prayed on by the leader of the People of the Stars, the [[Star Dragon King]], at the top of the [[Stairway to the Dragon Star]].

According to legend, the Crimson Dragon could only be Summoned with the help of the Signers, whose individual marks either represented the Heart, Hand, Tail, Wings, Foot and Head of the dragon. These people were being searched for by a group known as [[Iliaster]], disguised as the [[Sector Security]]. According to what [[Rex Goodwin]] told [[Yusei Fudo|Yusei]], he organized the [[Fortune Cup]] not only to confirm the identities of [[Yusei Fudo]], [[Akiza Izinski]] and [[Luna]] as [[SignersSigner]]s, but also in order to awaken their powers so that they could fight against their nemesis, the [[Dark Signers]]. [[File:Mark with Heart Sign WC2009.jpg|The Mark of the Dragon, including the Heart Mark, as seen in ''[[Yu-Gi-Oh! 5D's World Championship 2009: Stardust AcceleratorSigner]]''.|thumb|left]][[File:Mark with Heart Sign-WC10.png|The Mark of the Dragon, including the Heart Mark, as seen in ''[[Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia]]''.|thumb|right]]Interestingly, in ''[[Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator]]'' and ''[[Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia]]'', the Crimson Dragon full mark already had the Heart Mark on it. Whether this was an oversight or intentional foreshadowing is unclear, as ''Stardust Accelerator'' was released in Japan the day after the Japanese air date of [[Yu-Gi-Oh! 5D's - Episode 051|Episode 51]], the same with ''Reverse of Arcadia'' and [[Yu-Gi-Oh! 5D's - Episode 097|Episode 97]].

It is unknown, however, whether has not been specified if the Heart has ever heart existed before being given to Leo. It is also unknown whether Leo is a reincarnation as well, as both "[[Black-Winged Dragon (anime)|Black-Winged Dragon]]" and "[[Life Stream Dragon (anime)|Life Stream Dragon]]" have been seen in ancient flashbacks, though never in the same flashback, and from different time periods.

[[Roman Goodwin]]'s arm once possessed the Head Markhead mark, but was then severed from his body when [[Roman Goodwin|Roman]] became a [[Dark Signer]]. [[Rex Goodwin|Rex]] then later attached Roman's severed arm to himself through the powers of the Dark Signers though he stated that there was some resistance. Regardless he was able to call forth the marks of the other [[Signers]] as well. Towards the end of [[Yu-Gi-Oh! 5D's - Episode 064|episode 64]], Rex lost his Head Mark head mark when it transferred to [[Yusei Fudo|Yusei]], and Yusei's Tail Mark then whose tail mark selected [[Crow Hogan|Crow]] as its new owner.

In the dub, Yusei assumes that his birthmark is the Head head (which at the time was the Tailtail) after seeing [[Tenzen Yanagi|Yanagi]]'s sketch of the [[Crimson Dragon]]. However, it is proven to be a mistake as in the dub of episode 62 Rex confirms that his brother's mark is the Head head and not the Tailtail.

==Abilities & Behaviorand behavior==The Marks of the Dragon indicate a deep connection between the [[SignersSigner]]s, and represent this by glowing and throbbing at certain times, such as when a Signer is about to Duel against a [[Dark Signer]].<ref name="ep32">{{episode|Yu-Gi-Oh! 5D's|32|ref}}</ref>

The marks also rival the Dark Signer's [[Mark of the Shadows|dark mark]]. Whenever a Signer is in the presence of one of the Dark Signers, both of their marks react.<ref name="ep45">{{episode|Yu-Gi-Oh! 5D's|45|ref}}</ref> At times the Signer's mark will pulse very painfully on the arm it's is on.<ref name="ep27">{{episode|Yu-Gi-Oh! 5D's|27|ref}}</ref>

The marks give the Signer in question powers and abilities that no normal being possesses. They can be used to locate other Signers if they focus enough, even if the Signer in question is moving. So far, only [[Akiza Izinski|Akiza]] used this ability to locate Yusei when he was kidnapped by a rival team.<ref name="ep71">{{episode|Yu-Gi-Oh! 5D's|71|ref}}</ref> Also, a Mark of the Dragon will always shield the Signer itself or any companions close to them from harm or any other effect, like having their souls absorbed into an Earthbound Immortal or changes in the timeline.<ref name="ep39">{{episode|Yu-Gi-Oh! 5D's|39|ref}}</ref><ref name="ep117">{{episode|Yu-Gi-Oh! 5D's|117|ref}}</ref>

It is also shown that the The marks allow them Signers to see the [[Divine Temple]].<ref name="ep117"/> Anyone else touching the Signer is able to see it as well.<ref name="ep131">{{episode|Yu-Gi-Oh! 5D's|131|ref}}</ref> They also allow the Signer to activate the small, Ener-D reactors in his Duel Runner and continue to ride it, when all others in the city have stopped functioning.

[[File:Crimson_DragonCrimson Dragon's_seals seal.jpg|thumb|left|Crimson Dragon's previous original seal|thumb|left]][[File:Crimson Dragon's newest seal.png|thumb|right|The completed Crimson Dragon 's evolved seal.]]It is possible for a Signer to, temporarily, take control of all 6 Marks of the Dragon at once as the entire Crimson Dragon's seal, however the criteria for doing so is sketchy. [[Yusei Fudo]], [[Jack Atlas]], [[Rex Goodwin]] and [[Leo]] are the only [[Signers]] (past or present) to have done this, with the [[Legendary Signer]] (who possessed the whole mark on his chest) being the only one to (apparently) do so at will. Rex Goodwin was the only second Signer to have the entire seal on his chest (as opposed to the others who had it on their back) due to him having the [[Mark of the Shadows|condor mark]] on his back(but unlike the Legendary Signer (who had it on his left pectoral, over his heart), Rex had it in the middle of his chest).

Yusei and Jack did this inadvertently while trying to save [[Kalin Kessler]] and [[Carly Carmine]], respectively, and possessing all 5 marks allowed them to draw "[[Majestic Dragon (anime)|Majestic Dragon]]", with which to summon their respective "[[Majestic]] " Synchro Monsters. Rex was instead able to do so at will during the 3-vs-1 Shadow Turbo Duel against Yusei, Jack and [[Crow Hogan]]. However doing so did not seem to afford him anything non-cosmetic. Yusei was also able to take control of all 5 marks at the end of his Duel with [[Primo]]. [[Leo]] obtained the seal after being on the verge of death. While at this, the Heart Mark formed itself along Luna's Hand Mark hand mark within the seal, thus revealing it's true form of the original seal.

==NonVideo games=====''Yu-Gi-canon appearancesOh! World Championship''===[[File:Stardust accelerator's mark of the dragonWC09MarkoftheDragon.jpgpng|thumb|left|The player's Mark of the Dragon.]]

In ''[[Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia]]'' the [[Player (WC10)|player's character]] gets a Mark of the Dragon at the end of the game. Which mark is not clear since the full mark of the [[Crimson Dragon]] is shown. The three main theories are that the player recieves receives the Head, as Yusei doesn't mention a change in his mark, the Tail, giving Yusei the Head, or an unknown mark such as the Body mark, which returns from WC09, as The Shining Darkness is not available in-game, and therefore, Crow does not have Black-Winged Dragon in the game. In ''[[Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator]]'' and ''[[Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia]]'', the Crimson Dragon full mark already had the heart mark on it, despite both of them being released before its anime appearance. <gallery>Mark with Heart Sign WC2009.jpg | The Mark of the Dragon, including the heart, in ''[[Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator]]''Mark with Heart Sign-WC10.png | The Mark of the Dragon, including the heart, in ''[[Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia]]''</gallery> ===''Yu-Gi-Oh!

Duel Links]]'', the Marks of the Dragon are represented by [[Skill]]s that add that character's relevant Signer Dragon to the [[Extra Deck]] and two copies of an appropriate [[Tuner]] to the [[Main Deck]]. The full Mark of the Dragon is visible on [[Dark Signer Rex Goodwin]]'s chest.
