Scorpio
Super Name: Scorpio
Real Name: Jacob Fury (Lmd)
Nickname: Jake
Universes: Earth-616
Nicholas and Jake Fury were recruited by Leonardo da Vinci to act as Gemini and Scorpio for his Great Wheel collaboration. During their search for Renaissance tech, Jake was exposed to one of their finds which spontaneously created a full duplicate of him, the first "Life-Model Decoy".

As part of their own long-term plans, the Fury brothers kept the existence of the Jake Fury LMD a secret. The real Jake Fury went underground for many years after the Great Wheel dissolved, while his LMD became increasingly erratic. As a result, a good deal of insane or criminal actions committed by the LMD was attributed to Jake Fury over the years.

Sometime after the Great Wheel dissolved, Jake's LMD was approached by Cornelius van Lunt, alias Taurus, who asked him to join the Zodiac Cartel. At this time, Jake had also acquired the Zodiac Key, an ancient and powerful weapon that recognized the darkness inside of him. Jake used this as his primary weapon as a member of the Zodiac and created several false identities to hide from the world, like that of the champion racer Count Julio Scarlotti.

As Scorpio, Jake made numerous attacks on his brother and S.H.I.E.L.D., hiding his true identity from Nick. After a disastrous encounter, Jake lost his Zodiac Key to Nick, who used it to impersonate him as Scorpio for a brief time in order to bring down the Cartel. Scorpio was expelled from the cartel for his failures after this, and replaced with a new Scorpion, Jacques laPoint.

The Life-Model Decoy of Jake later had a complete mental breakdown. Still in possession of the Zodiac Key, Jake decided to create a new Zodiac to replace the one that abandoned him, using SHIELD LMD technology to do so. At this point in his life, "Jake" was unaware that he was an LMD himself. He had taken possession of a Nick Fury LMD, who served as a sounding board for his mad plans and a replacement for his estranged brother. Scorpio got into a confrontation with the Defenders. He demanded Kyle Richmond pay a ransom for their kidnapped friend Jack Norriss so that he could have the funds necessary to complete his army of Zodiac androids. Moon Knight tracked Scorpio down to his "theater of genetics" and was captured and left to die in a tank filled with water. At the same time, Nighthawk gave in and arrived in Washington to hand over the ransom to Scorpio, who reneged on the deal. When Nighthawk tried to attack, Scorpio blasts him with the Zodiac Key.

The Moon Knight escaped, but Scorpio now had Nighthawk as his hostage as well. The Defenders decided that they would need the Hulk's help in order to free Nighthawk. They tricked the green giant into following them to Scorpio's base, but they arrive too late, as Scorpio had activated his android Zodiac army.

The Defenders battled Scorpio's LMD Zodiac army, and with the added boost of the Hulk, the recently freed Nighthawk, and Moon Knight on their side, the Defenders gained the upper hand and seemingly destroyed the Zodiac androids set against them. Wrought with despair over his loss, Scorpio orders the LMD of Nick Fury to hand him a gun and promptly shot himself in the head.

Jake Fury rose again after this, resurrected by the power of the Zodiac Key and fully conscious of his status as a Life-Model Decoy. He succeeded in creating his next batch of Zodiac LMDs and battled the Avengers.

Next, Jake disposed of Jacques LaPoint and infiltrated the original Zodiac Cartel. His LMDs disposed of the human cartel, assuming their resources to become the only Zodiac Cartel. Scorpio led the Zodiac in a series of raids across the country, unaware he was feeding the Zodiac Key's desire for conflict instead of his own hunger for power. Scorpio arranged for two new LMDs to infiltrate the West Coast Avengers disguised as Hawkeye and Tigra, but both were eventually discovered. Scorpio finally overreached himself by ordering the Key to transport them all to the Key's home dimension. There, it was discovered that the astrologically powered Zodiac LMDs could not function, and so Jake Fury and his Cartel deactivated.
