Scorpio Ecarlate

Scorpio Ecarlate (蠍座(スカーレットニードル, Sukōpion no Escarlettu  ') is one of the 88 Saints Athena known as the Saints who protect their goddess through the different generations. Ecarlate is also one of the 12 Gold Saints that is protected by the constellation Scorpio and is therefore the Cloth.

History
As a young boy during his training as Saint Ecarlate  was bitten by a scorpion and contraced a very strange disease that made his body turn transparent. He was in verge of desperation when Ophiuchus Odysseus approached him. Odysseus visited Ecarlate and  came to the conclusion that it was a rare phenomenon where the molecules in the body align themselves in the same order as glass, hence why Ecarlate' body was transparent. Odysseus theorized that since scorpion's blood are blue due to hemocyanin, human haemoglobin would neutralize it and turn it invisible. The parts that were crystallized would continue to be refined eventually turning into gas. Ecarlate became frightened that he would soon disappear, but the Silver Saint suddenly told him that it was because of that reason Ecarlate had to become the Scorpio Gold Saint if he did not want to die. [1]

Odysseus brought Ecarlate to his study where he hooked them both up with a blood transfusion device. He said that the cause of Ecarlate's illness was in his blood, but if he replaced all of it with his own, then he would escape death. The young boy had heard the blood would be rejected unless it was a match, but Odysseus assured him they are compatible as he had "golden blood". It was said that one in a million possessed a universal blood type that could be donated to anyone. Ecarlate asked since he had donated to a lot of Saints and saved them all so far, wouldn't his body not give up soon. Odysseus told him not to worry about him. A Holy War would soon start, and if they lost that war, all humans would be driven from the land. Ecarlate had to survive and fight as a Saint, even if Odysseus died, since that was his mission.[1]

The transfusion would be repeated several times, and Ecarlate would seemingly recover from the illness, but Odysseus passed away. Ecarlate would mourn the death with all of the Sanctuary, as he was a much revered person.[1]

The young boy would continue his training until he finally became the Gold Saint of Scorpio.

Story
Ecarlate was in the temple Scorpio Temple when he noticed that a young unidentified Saint entered the temple. Ecarlate removed his Cloth and turned invisible. He ordered the intruder to leave and go back to where he came from, and if he did not, then he will die. The young man did not listen, so The Scorpio Saint used his "Restriction" technique on him to stop the intruder's movements. The young man introduced himself as Dragon Shiryu and told him that he came from the future to protect Athena. Ecarlate thought it was nonsense and told the man that he was probably one of the troublemakers of the Sanctuary, and should be punished accordingly for such behaviour. The Gold Saint proceeded to launch 5 Scarlet Needle techniques at the young man. The young man was able to break free from the Restriction, but was stunned as he noticed the Scorpio Cloth in object form. Ecarlate donned his Cloth while still invisible, shocking Shiryu. The Gold Saint wasted no time, and struck the man with a 6th "Scarlet Needle". The Gold Saint asked why he was not focused on their fight, as he had even gone through the trouble of putting his Cloth back on so that he could see his form. Shryu asked shockingly if he was an invisible man, to which he replied that he could make himself invisible at will and proceeded to turn himself visible.[2]

Ecarlate's process to turn himself visible had shocked Shiryu who asked how he had such a body. The Scorpio Saint replied that he would not answer such a wretch and told him to get out of there while striking Shiryu with a seventh Scarlet Needle. One more strike would kill the Dragon Saint, but the young man said that even though he would have liked to fight with him he could not die. Yet since it was the only way through the Scorpio temple, he would do it. Ecarlate called him a fool for fighting in such a condition and struck him with four more Scarlet Needles. With those strikes, the Bronze Saint would not be able to move, but Shiryu surprised Ecarlate by still moving around. The Scorpio was impressed, but warned him that another strike would be fatal. To his surprise, a dragon tattoo appeared on Shiryu's back while the latter raised his Cosmo.[1]

Shiryu said he had to continue for Athena's sake, and asked him to strike him with the final Antares strike. Ecarlate asked how such a wretch could know about Antares, to which the Saint replied that the Scorpio Saint of the future, Scorpio Milo had the same technique. This revelation of his successor surprised Ecarlate who started to believe the strange story of how Athena came from the future. He replied that Athena would however be unnecessary due to the revival of Odysseus, and that he would fight by his side. Shiryu said that he was mistaken. Despite the Dragon Saint's misgivings Ecarlate told Shiryu of how Odysseus had saved him as a boy from his rare decease via a blood transfusion. But continuously using his own body to save the Saints made the Saint's body weary and he would eventually pass away. He called Odysseus a god of the Earth.

Ecarlate asked Shiryu if he now understood the greatness of Odysseus, and that Athena would now be unnecessary. Shiryu protested which angered Ecarlate who said that if he could not understand it then the young Saint would die. The Gold Saint launched his final Antares strike at Shiryu who defended himself with an old wooden cane. To his surprise, the cane burst apart and revealed a blue gem.
