Kaidan Alenko

Kaidan Alenko is a human Sentinel and a Systems Alliance Marine. While serving aboard the SSV Normandy, he was a Staff Lieutenant and head of the ship's Marine detail. He also was an initial member of Commander Shepard's squad. Kaidan is a biotic wired with the controversial L2 implants, which are known to cause severe neurological damage to the user. However, he is fortunate enough to only suffer from occasional severe migraines. He is a possible love interest.

Dossier
Kaidan was born in 2151 into a family already familiar with space: his father served in the Alliance military. After his mother was downwind of a transport crash in Singapore, Kaidan was exposed in utero to element zero and beat the odds, gaining biotic potential instead of terminal brain cancer. At the time little was known about human biotics, but when the possibilities became better understood, a company called Conatix Industries was set up to track accidental eezo exposures. Children who showed enough potential to be worth augmenting with implants were 'encouraged' to attend BAaT (Biotic Acclimation and Temperance Training) which was conducted at Gagarin Station and nicknamed 'Brain Camp' by its attendees. As Kaidan tells Shepard, "a bunch of guys in suits show up at your door after school, and next thing you know, you're out on Jump Zero."

Along with several other teenagers, including a beautiful, gentle girl named Rahna, Kaidan began his training but things went bad almost from the start. Conatix wanted to speed the work along and brought in an ex-military turian, Commander Vyrnnus, who was an expert in biotics but also a veteran of the First Contact War who disliked humans. Vyrnnus introduced himself by saying "I was at the helm of the dreadnought that killed your father", and Kaidan retorted that his father hadn't even been in the war. Vyrnnus had it in for Kaidan after that, and began pushing the teenagers very hard. Kaidan recalls: "You either came out a superman or a wreck. A lot of kids snapped. A few died."

Finally, the inevitable happened and Vyrnnus went too far. Rahna, who had become close to Kaidan during their training, reached for a glass of water instead of moving it biotically. Vyrnnus punished Rahna by breaking her arm and Kaidan tried to defend her, only to receive a beating from Vyrnnus. When the turian pulled a knife, Kaidan lost control and hit him with a full biotic kick, breaking Vyrnnus' neck. After Vyrnnus' death, BAaT was shut down and the records were sealed to hide the Alliance's mistakes. Though Rahna was safe from Vyrnnus, she was afraid of Kaidan after that and the two parted ways.

Kaidan dropped off the radar for a while to figure things out, feeling lost and paralyzed after Jump Zero, but eventually came back to the Alliance in 2173 &mdash; on his terms this time &mdash; because he wanted to serve. Refusing further biotic training or an implant retrofit, he enlisted in the Alliance Navy and worked his way up to Lieutenant, gaining several special commendations in the process despite the health problems he suffered with his L2 implants; these manifested as intense migraines that left him sensitive to bright lights and noise. Finally Kaidan was transferred to the SSV Normandy under Captain Anderson, where he later worked alongside Commander Shepard.

His experiences at BAaT and his long service make Kaidan politically savvy, but very conservative, cautious and self controlled. Originally, Kaidan was hesitant to use his abilities on living targets, but he changes his mind after seeing the destruction on Eden Prime. During the mission on Eden Prime, Kaidan was deeply affected by seeing his comrade and friend Richard L. Jenkins gunned down, his first friend lost in combat. Though he is a biotic, Kaidan's loyalty is to the Alliance and he has no sympathies for biotic extremists. He doesn't bear any ill-will toward alien races, even turians: Vyrnnus made him see aliens as individuals and actually taught him how 'human' aliens are, "they're jerks and saints, just like us." Kaidan believes humans, as newcomers to the galactic community, shouldn't have a Council seat until they're ready for one, and Ambassador Udina is doing more harm than good by pushing too hard. Shepard can discuss this with him and (if female) can even Charm or Intimidate Kaidan into becoming much more xenophobic and pro-humanity.

If asked, Kaidan can give feedback on recent missions, discuss the commander's decisions and give some insight into the crew's state of mind. Knowing they're going to be faced with difficult choices without reinforcements, Kaidan urges Shepard not to cut corners as Vyrnnus did, and always leave a way out to ensure nobody gets hurt further down the line. However, as the mission progresses Kaidan becomes concerned about the lack of backup from the Citadel Council. The evidence Shepard is gathering about Saren Arterius and the threat of the Reapers seems too much to ignore, but the Council just doesn't want to believe anything's wrong &mdash; proving 'human nature' carries across species.

During the operation at Virmire, Shepard can choose to save Kaidan's life at the cost of losing Ashley. Kaidan is an experienced marine who knows that Ash volunteered for the mission, but he's never lost a soldier under his command to hostile action. Kaidan becomes determined to make the Council listen to their evidence about the Reapers: if all the Citadel races rally to stop the machines, it will be a fitting tribute to Ashley.

If Kaidan goes with Shepard to Ilos, he is moved by the fate of the Protheans, knowing their sacrifice has given them all a fighting chance. Unless Shepard has persuaded him to adopt a more xenophobic view, during the assault on the Citadel he tells Shepard to save the Council, even though he knows it will cost many human lives.

Romance
If Shepard is female, Kaidan is attracted to her from the beginning. He tries to save her from the Prothean Beacon on Eden Prime and, thinking he triggered it when he got too close, blames himself for her suffering. He also slips up when he, Ashley and Shepard are taking in the view on the Citadel by inadvertently admitting he finds the Commander beautiful, much to Ashley's amusement.

When the Normandy is locked down by the Council, Kaidan offers Shepard his comfort and support, and they almost share a kiss before being interrupted by Joker. Once they are finally en route to Ilos, Kaidan goes to Shepard to talk about the mutiny and the upcoming battle, wanting her to know that he's enjoyed serving alongside her. After some prompting by Shepard, he finally lets go; from what he can see, everything else in the galaxy, even the Reapers, will come around again, but the two of them are what is important right now &mdash; "this is what will never happen again. Us." Kaidan claims Shepard makes him feel human, and they can spend the night together, as long as nothing changes, and their duty to the Normandy's crew still comes first.

Mass Effect 2
If Kaidan survived Virmire, he continued to serve under Shepard aboard the Normandy. During a routine patrol hunting for geth forces, the ship came under attack from a warship belonging to the enigmatic Collectors and Shepard forced Alenko to evacuate with the rest of the crew. Soon after Kaidan got the survivors out in an escape pod, the Collector ship fired again, destroying the Normandy and causing Shepard's death. Suffering from survivor's guilt at the loss of his ship and his commanding officer, Kaidan remained in the Systems Alliance, eventually coming to terms with his pain. Over time he was promoted to Staff Commander.

In 2185, Alliance colonies began vanishing en masse, and Alliance Command began to wonder if Cerberus was responsible. Kaidan also began hearing rumours that Shepard was alive and somehow involved with Cerberus, then received a tipoff that the human colony of Horizon might be the next target. Kaidan was dispatched to investigate, and began installing defense towers as a cover for his investigation into Cerberus. However he ran into hostility from the colonists, who didn't like Alliance involvement in their affairs. They believed the defence towers actually made them more of a target, and resented Kaidan's presence.

The tip paid off when Horizon was attacked by the Collectors, though they arrived before the defence towers were ready. Kaidan tried to defend the colonists but was stung by a seeker swarm and paralysed. Somehow he managed to shake off the effects and avoid capture by the Collectors, in time to be reunited with Shepard, who had raced to Horizon to save the colony and activated the defence towers to drive off the Collector ship.

Though initially pleased to see the Commander, Kaidan soon became wary of Shepard's involvement with Cerberus. He refused to entertain any thoughts of joining the mission, claiming he was an Alliance soldier and always would be, and that he could never trust Cerberus. He left to report to the Citadel, but warned Shepard to be careful.

If Kaidan died on Virmire, while searching the wreck of the first Normandy, Shepard will briefly see Kaidan's face in a flashback. The Galactic News may also mention that an Alenko Memorial Fund has been set up and sending biotic children to the Ascension Project.

Romance
If Kaidan and Shepard had a romance in 2183, Kaidan takes her in his arms upon being reunited on Horizon, but his relief at seeing her alive soon turns to anger. He demands to know why Shepard didn't try to contact him and forced him to go through the pain of thinking she was dead for two years. He claims that working with Cerberus is a betrayal of everything they stood for, and leaves to report.

After leaving Horizon, Shepard receives an email titled "About Horizon..." from Kaidan:

For her part, Shepard will keep a picture of Kaidan in her quarters, on her desk between her personal terminal and the Medal of Honor. Should Shepard choose to maintain the relationship with Kaidan, before going through the Omega 4 Relay, she will gaze at the picture before leaving. If Shepard becomes involved in a relationship with another crew member, she will eventually turn the picture face-down on her desk.

Dossier
Kaidan returns to fight the Reapers, provided he survived on Virmire. If he did not, Ashley Williams will take his place in the squad. By the time of the events of the Reaper Invasion, Kaidan has been promoted to Major and commands the 1st Special Operations Biotic Company, a covert operations unit.

During the Reapers' invasion of Earth, Kaidan assists in evacuating Shepard from Earth on-board the Normandy SR-2. Kaidan then joins Shepard to a mission to recover Prothean data on Mars, where he displays great tactical and combat aptitude. However, he still does not fully trust the Commander, as he believes that Shepard may be a puppet for the Illusive Man. At the end of the mission, he confronts the Cerberus gynoid responsible for the base's destruction, but he is severely injured by it. He is taken to Huerta Memorial Hospital on the Citadel, where he slowly recuperates. While recovering, Udina offers a Spectre status to him which he accepts.

Shepard will be able to speak to Kaidan by visiting him in the hospital after every major mission. If Shepard romanced Kaidan, then there is the option to continue the romance. In time, Kaidan recovers from his injuries and accepts Udina's offer. When Cerberus invades the Citadel, Kaidan is tasked to protect the Councilors but is unaware that Udina and Cerberus are actually collaborating to take control of the Council. This puts Shepard and Kaidan in a conflict; Shepard must then convince Kaidan of the truth behind the attack.

Depending on past interactions with him, Kaidan can be talked down. If Shepard cannot persuade Kaidan to back off, Shepard, or one of Shepard's squadmates will kill Kaidan. If Kaidan lives past this event, he can either be recruited back into Shepard's squad on board the Normandy or left behind to provide assistance in the war. If made a war asset, Kaidan will send Shepard the following e-mail:

If Kaidan is brought aboard the Normandy, he spends his time in the Starboard Observation Lounge. Immediately after coming aboard, Shepard finds him gazing through the observation glass at the starry background. Kaidan contemplates about the millions of people who are being affected by the war and is frustrated at not being able to save them all. He tells Shepard about his mother who has been separated from his father due to the war and is all alone in the crisis. Shepard can offer words of sympathy and tell him to be strong.

On retrieving the Prothean Javik from his resting place, aboard the Normandy Kaidan mentions that while he doesn't mean to sound unprofessional, he can't stop grinning at the situation.

After the Cerberus scientists have been rescued, Kaidan will ask to see Shepard in the Crew Quarters. He asks Shepard about an insight into Cerberus, about how the people involved could have changed from their nature in 2185. He also ponders on the Illusive Man, wondering how he could have changed from an ally to an enemy. Shepard replies that they never anticipated the sudden betrayal from Cerberus and advises Kaidan not to dwell too much on the Illusive Man as his crimes have gone beyond forgiving, regardless of what his past intentions were.

Kaidan tells Shepard he really dodged a bullet after encountering Banshees on Lesuss. He quips that he never wishes to see the Ardat-Yakshi side of the asari again.

Later, Kaidan invites Shepard to lunch on the Citadel, saying that he needs a sanity check. If Shepard is not in a romance with anyone, Kaidan can make a pass the Commander at this point. Otherwise, he just expresses his admiration for Shepard and his consideration of Shepard as a good friend, to which Shepard can say that Kaidan is their brother.

After meeting up with Tali during the mission to sabotage a geth dreadnought, Kaidan good-naturedly calls her a good egg and says he is glad to have her back on the team. On second thoughts, Kaidan tells Shepard not to tell her he called her an egg, in case its a quarian insult.

Kaidan is amazed after Shepard shut down the geth servers on Rannoch by traveling into the geth consensus. Despite checking he Spectre division expense report at the time, he cannot stop trying to figure out Shepard's experience.

After the Battle of Rannoch, Kaidan is found playing poker with James Vega in the Port Observation Lounge. He doesn't seem to be able to compete with James, who plays poker regularly on the Citadel.

If Shepard sided with the geth, Kaidan remarks that the quarians' extinction was tragic and that he had always admired their resilience. If Tali survived until that fateful moment Kaidan says that he's sorry about Tali's death, remarks that she was "one of a kind", and he will miss her. He also says he'll never forgive the geth for Ashley and now Tali's deaths. If Tali died the previous year however, he wonders instead how history will remember the quarians.

If Shepard sided with the quarians, Kaidan will be glad that they are finally rid of the geth once and for all, stating that his experience with the synthetics mainly involved getting shot at. If Shepard managed to unite the two races, however, he expresses his amazement at the negotiation Shepard pulled off, further stating that having both geth and the quarians on their side is a very good thing.

After the the fall of Thessia, Kaidan is found in the Engineering Deck with Engineer Adams, talking sympathetically about Liara, who just lost her homeworld. They reminisce about her stories she shared with them back in 2183 and hope that she remains strong. Kaidan also attempts to raise the Commander's dampened spirits by promising that Kai Leng will get his ass kicked next time.

After dealing with Henry Lawson's shenanigans on Horizon, Kaidan expresses his palpable anger through words, stating that the Illusive Man better say his prayers because now that the team knows where his base is they're coming after him. If Kaidan was among the landing party he says he's never been more filled with rage after what he saw there. Illusive Man is obviously crazy in his opinion, and in cases like Sanctuary, Kaidan wouldn't mind killing crazy.

After the mission to investigate Leviathan on Mahavid, Kaidan is disquieted at seeing the people on the asteroid trapped ten years in the past and wonders how many more people are tapped like that.

During the Battle for Earth, Shepard can speak to Kaidan. Kaidan reflects on his years of service as a soldier and thanks the Commander for being able to reach his present position as a veteran. He is disquieted at having to say his goodbyes to Shepard, to which Shepard can offer an opinion.

If Kaidan was left behind on Virmire, or killed during the Cerberus coup attempt, his name will appear on the Memorial wall aboard the Normandy.

If Kaidan is in the squad at the final push towards the Conduit, he will be killed by Harbinger if Shepard failed to muster enough of the galaxy's forces for the fight.

Mass Effect 3: Citadel
If Kaidan is romanced, he will be the first one to come to Shepard's aid during the ambush in the Wards. Kaidan can also be invited to the party.

Shepard can also invite Kaidan up to their Personal Apartment. When he arrives, he insists on cooking a meal of "beef, bacon and beer, the food of (his) people" for Shepard.

Kaidan can also be used as a squadmate for Shepard for competitions in the Armax Arsenal Arena.

If Kaidan is sent to Admiral Hackett however he cannot return to the squad, or be invited to the party. He will also be unavailable for use in the Arena.

Romance
A female Shepard who romanced Kaidan in 2183 has differing dialogue with him during the mission to Mars, where they discuss their relationship, and Kaidan's fears that she is no longer the woman he loved. She can either be consoling or confrontational.

While in the hospital, Kaidan will send a message to Shepard asking to meet with her. If Shepard romanced another person in 2185, Kaidan will ask her about it, where she can either apologize, explain herself, or lie. Lying will make Kaidan angry and he will order her out of the room, although she has the chance to admit her lie and apologize. If she apologizes or attempts to explain, Kaidan remarks that he still cares about her, and there is no other woman in his life. Buying Kaidan a bottle of TM-88 Peruvian Whiskey from the Sirta Supplies store will cement their relationship further.

If Kaidan joins the crew after the Cerberus attack on the Citadel, Shepard can resume a romance with him, or start a new one if she did not do so before. He invites the Commander out for a drink at Apollo's Cafe, where he reminisces that he often had a few beers at his parents' home overlooking English Bay in Vancouver. He'll reflect on their relationship, and wonders if they have a future together. He'll also forgive them for cheating on him. Shepard can pursue the relationship by telling him that they love him.

If Kaidan was not romanced in 2183, either a male or female Shepard can start a new romance with him in 2186. They can do so by visiting him in the hospital, picking him up a bottle of whiskey from the Sirta Supplies store, and locking in the romance when Kaidan talks about how he never looked for a relationship before while at Apollo's Cafe.

Before the final battle, Kaidan will show up at Shepard's quarters offering "a quick drink". If playing a female Shepard who has rekindled a relationship with him, they will briefly discuss their first night together; otherwise, they will discuss the battle and their feelings before Kaidan admits that he didn't come for a quick drink.

During the final mission on Earth, Shepard can say their goodbyes to Kaidan. Kaidan will talk how he lived an amazing life thanks to Shepard and how hard he will fight so that he could hold Shepard again. If Kaidan is with Shepard in the final push to the Conduit, and if Shepard has mustered enough of the galaxy's forces, he will be badly injured by Harbinger's beam and will be evacuated to the Normandy. Shepard and Kaidan will profess their love for each other before Shepard goes to the Citadel beam.

If Shepard decides to fire the Crucible and Kaidan survived the final battle, he will be the one to put Shepard's name on the Memorial Wall or if the galaxy's military strength is sufficient and the Reapers are destroyed, he will refrain from putting Shepard's name on the Memorial and smile.

Trivia

 * If Shepard has any biotic talents, Kaidan will claim that though his abilities spike higher than most L3s, Shepard is the exception, indicating that the Commander is an L3. This appears to occur regardless of Shepard's class.
 * On the PS3 version of Mass Effect 2, if Kaidan died on Virmire, his picture may appear in Shepard's cabin even if he was not the chosen love interest in Mass Effect: Genesis, possibly caused by a glitch in the game.
 * His name is sometimes spelled "Kaiden" in external media (such as the Character Spotlight), but is always spelled "Kaidan" in-game.
 * Raphael Sbarge also voiced Republic officer Carth Onasi in BioWare's Star Wars: Knights of the Old Republic.
 * Hidden dialogue shows Kaidan at some point was intended to be a romance option for a male Shepard in Mass Effect, but this option was removed in the final version. It is possible for a male Shepard to have a romance with Kaidan through the use of save edits, although some of the dialogue options are missing.
 * When Kaidan is encountered in the opening for Mass Effect 2 and later on Horizon, he is wearing Medium Armour, though in Mass Effect, he could only equip Light Armour.
 * On November 24, 2011, Raphael Sbarge, as a Thanksgiving Day present, released a sound file where he voices Kaidan's apology email to Shepard in Mass Effect 2 after the two meet on Horizon. The sound file was later taken down but was rereleased on YouTube


 * As with all squad members, Kaidan has unique dialogue that can be heard at various locations, during missions or assignments, or if a specific squad member is in the selected team.
