Jetstream Sam (Metal Gear Canon)

"We've both heard enough speeches about higher causes by now. History will decide who's right. End of story."
SAM TO RAIDEN

Samuel Rodrigues, also known as Jetstream Sam and Minuano, was a cyborg mercenary involved with the Desperado PMC group who fought against Raiden during the events of 2018. He was a master swordsman of the "Rodrigues New Shadow School" technique, which had derived from the "Yagyu Shinkage-ryu (Yagyu New Shadow School)" of Japan.

Early life and career
Samuel Rodrigues was descended from a long line of swordsmen, dating back to 16th century Japan. His father ran a Brazilian Kenjutsu dojo, and specifically taught the Uradachi technique, better known as Satsujin-ken or "the murdering sword," which dealt with violence as the end goal. Sam's father was eventually killed by one of his pupils, with one of the drug cartels being rumored to have been involved for reasons and methods unknown, although not before Sam personally inherited his Murasama blade from his father. He then left Brazil, presumably to train, and eventually returned to kill the pupil in question before leaving Brazil permanently.

Afterwards, he travelled the world as a mercenary, and taking various odd jobs, including a job as a bodyguard and as a cleaner for the Mafia and the like. He also made a name for himself in the criminal underworld, especially within South and Central America, with one story being that he managed to take down a hit squad composed of 10 mob enforcers with automatic weapons using only his sword during the early 2000s, a time before cyborg technology was available. At some point, he had the Murasama blade modified into an HF blade with an ID lock. Already a superlative sword, this led to the creation of an incredibly powerful HF Blade which glowed an eerie red color.

Recruitment by Steven Armstrong
At some point, Sam learned about Steven Armstrong's involvement with World Marshal, and decided to kill him for "sacrificing soldiers from the comfort of an office." Unbeknownst to him, however, Armstrong and Monsoon had arranged for his arrival at Denver to recruit him, in large part because of his taking out several drug cartels. He proceeded to infiltrate the compound via the sewer systems of Denver, although not before killing two DPD cyborg police officers who caught him attempting to enter. He later encountered the LQ-84i prototype unmanned gear who had orders to kill Sam, presumably from Armstrong. Sam proceeded to tell him that he should think for himself. The LQ-84i briefly considered his advice, but was unable to disobey his directives due to Desperado blackmailing him with a memory wipe. The LQ-84i was then defeated by Sam, with him mentioning that he fought of his own choosing as why he prevailed over the mech.

Leaving the ruined mech behind, he then proceeded to enter the premises of World Marshal. Upon gaining entry, he then attempted to use the lifts, although his presence activated a lockdown on the lifts before he could reach his destination. Sam, upon defeating the reinforcements, managed to reach his destination by jumping up on the crates and eventually entered a hangar area. He then encountered Monsoon, who questioned his motives regarding his slaughtering of a drug cartel. Sam told Monsoon that he left Brazil since he had no need to stay anymore due to his exacting revenge (referring to his father's death at the hands of one of his pupils). After a debate regarding the consequences of Sam's actions, Monsoon dropped a RP grenade down to his level and then summoned a Metal Gear RAY UMG unit to attack him.
Upon the defeat of the RAY unit, Armstrong then proceeded to invite Sam to the roof via the PA for a "final test." Sam then fought his way through the building until getting to the outside of a Japanese garden plaza, where Monsoon questioned his resolve, citing that he can't take out an organization as big as World Marshal all by himself, even if he "removed the limbs," although Sam retorted that he only fought for himself. When Sam boarded an elevator to the roof he was contacted again by Armstrong, who noted how they both shared similar views, despite Sam's protests against the claim. Sam then proceeded to locate several doors on the top floor, including the door leading to the rooftop of the HQ building.

Sam then encountered Armstrong on the rooftop after defeating a Hammerhead. Armstrong, as his "final interview", powered up to his maximum form, the spectacle of caused Sam to applauded the transformation. After an intense battle, Sam seemingly was victorious over Armstrong. However, Armstrong stood up again virtually unharmed by Sam's assault. Armstrong then requested that he lend them a hand so they could end war as a business. Sam refused and decided to take Armstrong's hand rather than give them one. After making a few swings at Armstrong with his sword, Sam paid close attention to the speed at which Armstrong's nanomachines form his armor. Then, after taking a few punches, he made use of the explosive charge in his sheath to sever Armstrong's right hand. However, given the sharp angle the cut had left, Armstrong propelled the nanomachine hardened stump into Sam's right arm. Forced to concede defeat, Sam accepted the senator's offer and joined World Marshal.

Sam's right arm was then replaced with a prosthetic, owing to the severe damage to it that Armstrong inflicted on him. He then participated in several missions with the restored LQ-84i during this time.
Sam, alongside Desperado, ambushed African Prime Minister N'mani's convoy, blocking the lead vehicle. The gunner of the lead vehicle then requested that he stand aside, also warning that he'd use lethal force if he did not comply. Sam then proceeded to rush at the vehicle, dodging the gunner's machinegun fire before jumping at the air, deflecting the incoming bullets and then slicing him in half with his sword. He was then surrounded by the remaining soldiers of Maverick while the Prime Minister's limousine escaped. Smirking whilst watching them leave, he knew that their escape was fruitless. He then proceeded to slay the Maverick cyborgs as well as several national soldiers.
Eventually, N'mani was captured by the Desperado leader Sundowner and the two men rendezvoused on the train, the latter having boarded it to evade Maverick when surrounded. Afterwards, Maverick member Raiden boarded train himself in pursuit of Sundowner, attempting to stop Sundowner from killing N'mani, but hindered by the presence of Sam. After Sundowner made his escape, Sam challenged Raiden to a duel aboard the train while inside the train tunnel. Sam easily blocked Raiden's attacks because of their different sword techniques and Sam's unique HF Blade. Raiden could not keep up with Sam's blows and Sam managed to first damage Raiden's left and Artificial Compound Eye with an upwards cut. During this encounter Sam managed to see through Raiden's technique, praising it as "not half-bad" despite Raiden being a self-taught swordsman. However, Sam declared that Raiden was "denying [his] weapon its purpose" and that in reality it had a desire to kill.[1] After rupturing a propane tank to ignite his sword he pushed Raiden back and then sheathed his sword. Raiden rushed at Sam but the flames obscured his vision, leaving him vulnerable to Sam's impending counter-attack. In one clean motion, Samuel used the trigger release on his scabbard to unsheath his sword and sever Raiden's left arm. Samuel continued to taunt the crippled Raiden in his vain attempts to continue the fight. He then attempted to finish off Raiden, but realised that Raiden stalled him long enough for them to reach the end of the tunnel and was forced back by Maverick's reinforcements before escaping onto the Tiltrotor. His escape was ensured with the built-in flares of the aircraft when Maverick commander Boris attempted to shoot it down with an anti-air missile.

Following this encounter, Raiden would hold a deep grudge against Sam. Sam would also tell his comrades, particularly Monsoon, of his observation from earlier that Raiden saw his weapon "as a tool." Sam's weapon is passed down to him from his father indicating that there is a lineage of swordsmen in his family, likely stemming from his Japanese ancestors who escaped from Japan to Brazil during the second World War.

Sam later hacked into several billboards during Raiden's mission to storm World Marshal Inc.'s HQ building at Denver, where he proceeded to give a breaking lecture on how Raiden's means of pursuing justice had blinded him to the idea that the cyborgs may have been forced to do things they didn't want. He later observed Monsoon's lecture towards Raiden and wanted to fight Raiden's Jack the Ripper form, but Monsoon declared that Jack was his to fight, and instead was ordered to report to the chief. He eventually was ordered to fight Raiden by the dying Sundowner after he had been finished off by Raiden at the top of World Marshal HQ.
He later had a final duel with Raiden in the Badlands of Colorado, with Blade Wolf bearing witness to it. He was killed by Raiden in the Badlands by a swift stab through his torso following an intense battle. Prior to his duel and ultimate death, he confided in Blade Wolf, wondering whether or not his actions were right after seeing that the convictions held by Raiden were once his own. Depending on what the outcome was, they would either continue with the planned international incident Operation Tecumseh, or he would hand down his sword to Blade Wolf and leave him with the decision of what to do with the sword. Blade Wolf would eventually deliver the sword to Raiden when he was at Armstrong's mercy.
Upon Sam's death, Raiden discovered that Sam barely had any cyborg enhancements at all. In fact, besides the exoskeleton that encased his otherwise-human body, only his right arm was actually purely cybernetic.
