User:Teugene/Sandbox/Kai Leng

Kai Leng is an assassin working for the human-survivalist organization Cerberus. Leng was formerly a lieutenant and N7 marine in the Systems Alliance known for having anti-alien attitudes. He is described as being Earth-born with features that show his dominant Chinese heritage.

Kai Leng is voiced by Troy Baker.

Background
Leng's prowess in combat and xenophobic nature drew the attention of the Illusive Man, and Cerberus helped liberate Leng from prison. The Illusive Man used Leng as his best wet-work operative and assassin for over a decade, realising he was not only ruthless but discreet and methodical. Leng became the Illusive Man's most trusted agent, working as an infiltrator and assassin. His cybernetic modifications appear to include Cerberus's Phantom-class implants.

Mass Effect: Retribution
When Cerberus confirmed Paul Grayson was on Omega, Leng was charged with hunting down and capturing him. Leng and a squad of six other Cerberus operatives captured Grayson. During the mission Leng personally killed Liselle, the daughter of Aria T'Loak and Grayson's lover. He was then ordered to oversee Grayson during the Reaper nanotechnology experiment. It was Leng's idea to dose Grayson with red sand to lower his resistance to the Reaper technology.

The Illusive Man ordered Leng to exterminate Grayson when the experiment became too dangerous to continue, or if he got out of control. However, when a turian strike team raided the research facility that housed Grayson, Leng chose to rescue the Illusive Man rather than kill Grayson, meaning Grayson was rescued by the turians. After the assault, the Illusive Man sent Leng to Aria as Cerberus' representative, both to negotiate for her assistance in finding Grayson, and to keep an eye on her.

After Grayson escaped Omega, Kai Leng offered David Anderson and Kahlee Sanders - who were both looking for Grayson - a ride off Omega, in exchange for their help in taking out the Reaper-possessed monster Grayson had become. Knowing he was a Cerberus agent, Anderson and Kahlee attacked Leng, but he got the upper hand and asked again for their help, knowing Kahlee was the key to finding Grayson. They reluctantly accepted; however, when confronted with turian security guards near Leng's shuttle, they took their chance. After distracting Leng, Anderson tasered him, then convinced the guards to let him take Leng's limp body. Leng was then tied to the copilot chair with rope from the shuttle's med kit. During the journey, Kahlee realised the Reapers were sending Grayson to the Jon Grissom Academy, home of the Ascension Project.

Upon arrival at Grissom Academy, both Anderson and Sanders left the shuttle to protect the biotic pupils at the Project, leaving Leng tightly bound to the chair. After a struggle with the rope that left him bleeding, Leng managed to free himself and get into the Academy. He later encountered a gifted biotic student named Nick, and needing Nick's biotics in lieu of a weapon, managed to persuade Nick that he was on his side.

On his way through the Academy, Leng heard Grayson in the distance, prompting both he and Nick to hide in a nearby empty room. Leng intended to ambush Grayson using Nick's biotics, but when the attempt failed, Leng tried to steal Grayson's weapon. He failed and was almost killed, only to be saved by Anderson, who killed the Reaper-controlled Grayson with a shotgun.

Anderson refused to simply let Leng escape; however, Nick had been shot and was badly hurt. Anderson had to choose between saving Nick and letting Leng go, eventually choosing to help Nick - though not before wounding Leng in each leg to try and slow him down. Despite his injuries, Leng still managed to get back to the shuttle and escape. He was able to report to the Illusive Man, who assured him that despite the failures of his mission, he was still an asset to Cerberus.

Mass Effect: Deception
''This section features material from the first edition of Mass Effect: Deception, which BioWare has acknowledged contains discrepancies with other Mass Effect lore. Once revised editions of the book are released, this section will be updated.''

By the time of Mass Effect: Deception, Kai Leng's wounds have healed but he uses a cane when walking. He can still fight much as he used to, but the exertion can cause considerable pain in his legs. When a design for a DNA-specific bio-weapon tailored to attack the Illusive Man is stolen, Leng tracks it to an auction house in the city of Thondu on the batarian homeworld of Khar'shan. Leng steals the design and escapes. Later, Leng arrives on an uninhabited world in the Crescent Nebula and receives new orders from the Illusive Man: retrieve Paul Grayson's body from the Citadel and monitor the activities of David Anderson and Kahlee Sanders.

Mass Effect 3
In Mass Effect 3, Kai Leng is amongst the forces that Cerberus sends against Commander Shepard. Like Cerberus Phantoms, he is equipped with a palm device that projects a kinetic barrier, a tactical cloak and a sword for close-range combat.

Leng, along with a sizable contingent of Cerberus forces, were deployed during Councilor Udina's attempted coup against the Citadel Council. He was close to assassinating the Salarian councilor when Shepard and either Major Kirrahe or Thane Krios interfered. After a brief skirmish, Leng managed to escape after stabbing Krios/Kirrahe. If both Thane and the major had previously died, Leng will successfully assassinate the councilor.

In a race to get to the Council, Leng disabled Shepard's X3M, but ultimately failed his mission and was forced to retreat as C-Sec began to regroup. As he escaped, Leng reported his failure to the Illusive Man and promised to never let Shepard get the better of him again. It's revealed that Leng released a VI into the Citadel mainframe that erased all footage of himself. Bailey presumes that Leng didn't believe that Udina's plan would succeed.

Leng re-encountered Shepard on Thessia while being invaded by the Reapers, in a race to get data on the final Crucible piece from a hidden Prothean Beacon. Again, Leng is unable to stop Shepard, so he instructs his gunship to level the temple. The floor caves in, leaving Shepard alive but unable to act as he claims the data. After the mission, Leng sent a message to Shepard titled "Evacuating Thessia", disguised as asari military command:

Samantha Traynor was able to track Leng to Horizon, where Henry Lawson was conducting experiments on refugees. At the same time, ex-Cerberus operative Miranda Lawson was there, looking for her sister. The Illusive Man reminded Leng to get the data but to kill Miranda only if she got in the way. Leng wounded Miranda when she confronted him, but otherwise left her alone. He managed to complete his primary objective, but was unaware that Miranda had tagged him so Shepard could strike back at Cerberus.

Shepard's final confrontation with Leng takes place during the Alliance raid on Cronos Station, when the assassin (along with a cadre of Nemesis Guards) confronts the Commander on the observation deck of the station. Despite Leng's lethal skills, he's unable to overwhelm Shepard. With his shielding depleted, he soon succumbs to attacks from Shepard's squad.

However, despite his heavy wounds, Leng retrieves his blade and silently approaches Shepard to kill the Commander from behind. At the critical moment, Shepard detects him and counters his attack. The Commander can either break Leng's sword while stabbing him with an omni-blade, or dodge the attack and stab him with the omni-blade. With either outcome, Shepard ends the life of Cerberus' greatest assassin.

Combat
''' SANDBOXING NOTE: THIS SECTION AND ADVERSARY TEMPLATE IS JUST A FILLER. NOT ACTUAL CONTENT. '''

Capabilities
Offensive

Phantoms are deadly in melee combat. A Phantom's most feared weapon is its ability to kill its target in melee without any chance of getting revived. They also possess a powerful semi-automatic projectile-based weapon, shot from the palm of their right gauntlet.

Defensive

While they are protected by biotic barriers, Phantoms rely on their agility to evade enemy fire. They can quickly sidestep, roll, or leap away from attacks, disorienting the player. If endangered, Phantoms will also activate cloaks and take cover for a short period. They can recharge their barriers and their health over time.

Tactics
General Tactics
 * Phantoms are almost as, if not more dangerous than Atlas mechs in terms of the damage they can inflict. The safest way to deal with them is from a generous distance. While they possess a ranged weapon, they only employ it while relatively close. At longer ranges, they attempt to take cover or activate their cloak instead.
 * Phantoms can instantly kill a character in melee, but only if their target is in range. Moving away denies them their instant-kill attack, but they can still kill you with sword and gauntlet shots.
 * If you want to leave her close range, fire any projectile power with a travel time, such as Warp, Singularity, Throw, Incinerate or Cryo Blast. The Phantom will attempt to dodge the attack, which delays her attacks for about two seconds. You can use this opportunity to run away.
 * Since the Phantom is able to dodge most projectile powers, it not recommended to use these powers with the intention of damaging the Phantom. It has also been noticed that Phantom can use warp to replenish it's barrier. However, if you have a very fast cooldown, you could spam warp and other powers and damage it as the Phantom will not dodge the second or the third attack.
 * If a Phantom cloaks, try to focus weapons fire on it as long as possible to disrupt the cloak, otherwise it will be completely invisible. At very close range, the cloak is as visible as an infiltrator employing Tactical Cloak.
 * Particularly in the later rounds of multiplayer matches, Phantoms are prone to pairing up with a Nemesis. Because the Nemesis has no close range attacks, and is best dealt with by melee attacks or shotgun blast, it serves as a very effective lure for the Phantom. Keep this in mind when watching Nemeses move around the battlefield; if they remain in one corner for an extended period, they are likely being used as bait by a nearby Phantom.

Class/Character-Specific Tactics
 * Phantoms are fortified well with a biotic barrier; however, high-ranked Energy Drain or Overload can take down the Phantom's barrier in one use, which will leave her health open for any attack. A properly leveled Engineer can capitalize on the Phantom's cloak-and-cover defense by using either of these techniques, followed by Incinerate to hit around cover. This is a good way to keep them disoriented and on the run.
 * The Infiltrator is capable of using the Phantom's own tactics against them, with a combination of tactical cloak and melee attacks for massive damage or possibly one hit kills if handled carefully. With enough melee damage upgrades, they are capable of killing Phantoms with a single heavy melee while cloaked. This is a very risky attack, as missing or failing to kill the Phantom will leave you very vulnerable and easily killed.
 * Using a shotgun as an Infiltrator is another viable option, as it lets you deal considerable damage coming out of tactical cloak while still being mobile enough to strafe or backpedal away from the Phantom's counterattack. By using the cloak in short bursts, you can minimize recharge time and continue to use the cloak's damage bonus, or give yourself time to evade and reload without interruption.

Trivia

 * According to The Art of Mass Effect 3, early concepts of Kai Leng gave him metal legs and hard armor, but this evolved into a stealthier appearance with a coat reminiscent of Thane Krios'. His face and body kept a few obvious cybernetic implants to imply that he had been modified since the events in the books to become even deadlier.
 * According to the Mass Effect novels, Kai has both Chinese and Russian/Slavic heritage, with the Chinese being the dominant of the two.
 * The weapon wielded by Leng appears to be based on a Japanese "Ninjato"- a straight (and often shorter) variant of the Samurai's Katana. The weapon suits Leng's style- being designed to inflict quick lethal blows at close range.
