Aeon is the het ship between Leon Kennedy and Ada Wong from the Resident Evil fandom.

Resident Evil 2 (2019)
 In 1998, Leon and Ada first meet while in a parking garage of a dying Raccoon City, amidst the outbreak. As Leon is attacked by a zombified dog and struggling to hold it off, a woman shoots the dog off, saving him. The woman comments she's "surprised he's made it this far". She flashes an FBI badge and declares any information to be classified when Leon asks what's going on, after thanking her for helping him. Leon is soon left dumbfounded and alone as the woman walks off through a door.

Leon leaves for the woman's direction where he's met by an imprisoned man. Before Leon can get any answers of him, he's killed by Mr. X, a tyrant stalking survivors. With the man dead, the woman emerges from the shadows and Leon holds his gun to her, believing her to be Mr. X. Realizing it's her, Leon tells her he "has no idea who she is," giving his own name. She tells Leon to get out of the city and then they'll talk, before again walking away from him; telling him "Name's Ada."

A little later, back in the parking garage, Leon in confronted by Mr. X, having just narrowly avoided him a minute prior. The Tyrant has Leon by the neck when Ada drives a S.W.A.T van into it, causing it to release Leon. As Ada exits the vehicle, she exclaims, "This is getting old. Saving your ass— that's twice!" Leon half-heartily jokes that he "didn't realize she was keeping score," when Ada snaps at him again that "this isn't a game". Ada planted a bomb on the van, which she detonates as she sees Mr. X start to move the van. She asks if Leon has the key card for the parking gate, which he does. The two make for the main street outside and upon seeing the road out; they detour through a gun shop. There a man, Robert Kendo, points his gun at Leon, to which Ada points hers at him. The encounter is interrupted by Robert's daughter, Emma Kendo, who is quickly revealed to be infected. Ada attempts to kill his daughter much to Robert's objection; however, she's stopped by Leon. Robert picks up his daughter and walks for a backroom, while demanding privacy. A shot rings out indicating he mercy-killed her. As Leon watches them leave, he makes it known to Ada that he will do whatever it takes to save the city, that helping people is why he joined the police force. Ada tells him that her mission is to take down Umbrella's entire operation. Leon insists that he's willing to what it takes and the two becomes allies.

They head for the sewers, where Ada informs Leon that she's looking for a woman named Annette Birkin, the one responsible for unleashing the G-virus into the city. The deeper they go, the sewer shakes like an earthquake, when Leon comments "again," Ada tells him that "it's not too late for him to turn back," to which Leon tells her that she's stuck with him to the end. After encountering a massive, mutated alligator, they eventually find Annette Birkin. Annette runs and Ada runs after her. After rounding a corner, Annette fires at Ada and Leon shoves Ada down, taking a bullet to his left shoulder for his efforts. Before Annette can get too far ahead, Leon insists Ada go after her without him. Leon passes out and, before Ada leaves for Annette, she leans him against a wall, bandaging Leon's wound and covering him with her overcoat.

Ada eventually finds Annette, and in an ensuing confrontation, Annette moves heavy machinery after Ada, causing her to fall off the catwalk she was on and a piece of metal to impale her thigh as she rolls down a high pile of garbage. As Ada lay there in pain she comments "Where's Leon when I need him..." before passing out.

Elsewhere, where Ada left Leon, Leon wakes and immediately calls out for Ada. Realizing she's not there, he begins his search for her. He eventually finds her still at the bottom of a garbage pile in waste disposal. Upon entry, he finds Ada awake, but unable to walk with the piece of metal embedded in her thigh. Leon warns her of the pain, before pulling the metal out. Through her pain, she tells Leon she can patch herself up, but Leon insists he do it instead. Leon asks what they should do now to continue their mission, when Ada tells him that he "get himself out of there while he still can". Leon again insists that he's not going to leave her, when Ada informs him that the situation was worse than she thought. Not backing down, Leon reminds her that she protected him, so now it's his turn. Leon reaches down to help Ada help, which she accepts. He tries to help more by wrapping her arm around his shoulder, but Ada pushes him back lightly, telling him, "Don't push it, rookie". Respecting her wishes and without touching her, Leon guilds Ada up the garbage pile. As they're walking, Ada tells Leon if he really wants to help her, they need to get to NEST, Umbrella's lab located directly below them. Leon jokes that he can "fit it into his schedule".

They make for a cable car that'll take them down to NEST, where Ada uses an ID wristband she stole to gain access. Ada tells Leon that this "may be a one-way ride," and to make sure he's prepared. With that, Leon starts the cable car and begins the descend for NEST. During the ride, they talk about trust and after Ada calls herself a liability, Leon starts going on how what if she's attacked, or if she's in need of help, to which Ada kisses him. Once she pulls back, she tells him not to worry about her, and then assures him she wants to see him again. As they arrive to NEST, Ada gives Leon the ID wristband, and he exits from the cable car while Ada stays put.

Following a battle with the mutated William Birkin and a conversation with Annette, Annette tells Leon to destroy the G sample he's got. Leon tells her no — that it's evidence, it's going to the FBI. Despite the amount of pain Annette's in, she laughs, questioning, "You trust that bitch?" Leon is confused and asks what she means, and Annette tells him Ada is not FBI, she's a mercenary — she's going to sell the G-virus to the highest bidder. Annette seemingly succumbs to her injuries, but not before telling Leon she hopes he's right about Ada.

Leon and Ada meet in the middle as the facility begins to self-destruct. Ada gestures for Leon to hand over the G-virus but Leon instead informs her that Annette claims Ada's not FBI. Ada pulls out her gun, holding it to Leon, in return Leon holds his own to her. He confirms that, as much as he wanted to trust Ada, he didn't. The two go back and forth, with Leon challenging Ada to shoot him and, after a minute she lowers her gun, unable to do so. Annette then shoots Ada in the shoulder and the platform-bridge they're standing on begins to collapse. Ada falls over the edge, with Leon yelling her name as he catches her by the hand. Despite Leon's best efforts to save her, Ada falls down the massive shaft. Leon eventually picks himself back up as more of the bridge falls and runs for the elevator down to the train system. Before he can reach the system, he's met again by Mr. X. The two engage in an intense battle as the facility continues to crumble around them. Ada, having survived her fall, pushes a rocket launcher down to Leon, noting that "We'll call it even." before disappearing.

Leon reaches the train system, barely managing to jump aboard the moving train. Once he's down and has a moment to catch his breath, he pulls out the ID wristband Ada gave him, commenting "I can't believe I actually miss her..." before tossing the ID wristband onto the tracks.

Resident Evil 4 & Separate Ways
 In 2004, Leon and Ada are on separate missions in an undisclosed village in Spain; Leon, to rescue the United States President's daughter, and Ada, to steal a specialized sample of the Plaga held by Saddler. Although they both enter the village around the same time, Ada is able to leave quicker, using the chaos Leon was causing as a distraction from her own escape. She is able to reach a church outside the village and ring the bells, causing the villagers fighting Leon to stop and leave the area.

Leon later reaches a house outside the village and runs into Father Bitores Mendez, who easily picks Leon up before throwing him to the ground and choking him with his foot on his neck. Ada, overhearing their conversation from the roof, drops down outside a window and shoots Mendez in the back, causing him to get off of Leon and turn his attention towards her. As Mendez charges Ada, she ziplines up to safety, causing Mendez to crash out the window and to the ground below, and allowing Leon a chance to escape. Before Leon continues, he can look out the window and question to himself, "Woman in red... somehow so familiar."

The next time Leon and Ada meet is when Leon exits the castle's garden. Ada holds a gun to his back, yet Leon is quick to disarm her of her weapon with his knife. Ada removes her sunglasses, noting that it's been a while since they've seen each other, and drops the glasses to set off a timer for a smoke bomb. Leon questions her, revealing that he knows she's working with Albert Wesker, although Ada doesn't provide any answers. The smoke bomb goes off and Ada makes her escape out a window, telling him "See you around." and leaving with Leon yelling her name.

Ada escapes to the garden below, answering a call from Wesker, who is now aware of Leon's presence in the area. Although Ada tries to dissuade him from doing anything, Wesker orders her to kill Leon the next time she sees him. Ada defies his orders, instead purposefully avoiding Leon so that she has an excuse for Wekser when he eventually asks why Leon is still alive.

Leon and Ada don't meet again until Leon is on his way to a nearby island in his continued rescue of Ashley, the President's daughter. Ada is sitting and waiting in a docked boat when Leon emerges through a door. Before Leon has time to say anything, Ada looks up, asking him if he needs a ride. Ada then takes them to a cliff side of the island. Ada informs him she has other business and leaves, not before pushing her foot off the steering wheel, causing the boat to lose control and Leon to slam against the cliff side. As Leon manages to regain control, he comments to himself, "Women..."

Later, Ada throws a paper airplane with her signature red lipstick kiss into the cell room Leon is just about to leave, saying "Perhaps you have fingered it out all ready, but you might be able to get out of here by using the waste disposal vent".

Sometime later, Wesker contacts Ada about the chaos Leon has managed to make with his life still intact. Ada once again tries to dissuade him on Leon's importance, although Wesker notes that Leon's death is now Jack Krauser's responsibility which stops Ada in her tracks. Wesker reminds her that her job is to retrieve the sample and hangs up, but Ada notes that she doesn't always play by others' rules and begins running to intercept Krauser and prevent Leon's death. Krauser manages to track Leon and engage him in an intense knife fight, with Leon eventually on the losing end. As Jack is attempting to stab him through the chest, Ada shoots Jack's knife away, forcing both men apart. With Ada there, and clearly on Leon's side, Jack leaves. Once he's gone, Ada questions Leon if he and Jack knew each other, to which Leon implies yes. Looking for his own answers, Leon asks Ada what she's doing there at all, but Ada merely walks away, leaving him.

Leon and Ada meet up again when Leon starts to succumb to the Plaga infecting his body. Ada walks up to him, asking if he's okay, though Leon doesn't answer. Instead, he struggles to gain back control of his body as Ada moves herself closer to him, reaching out. Leon turns to her and wraps his hands around her throat. Ada is too stunned at first to fight back, but she manages to take a small knife out, stab Leon's thigh and force him away by kneeing his abdomen. Leon picks himself up and apologizes to Ada, taking more suppression pills for the Plaga given to him by Luis Sera. Ada tells him they need to get the Plaga out of his body and Leon agrees, though he needs to rescue Ashley first. Ada tells him fine, and that they need to split up. With that, she walks out the door, leaving Leon alone.

Leon finds Ashley, though is soon confronted by Saddler, Saddler harshly shoving him against the chamber Ashley is in. As Leon struggles to stand up, Saddler approaches. Ada appears on a catwalk above, firing multiple rounds of her machine pistol into Saddler and giving Leon time to stand up and rescue Ashley. Saddler, unaffected by the bullets, mutates and begins heading for Leon again. As Leon is making his way out, Ada attempts the same thing — to shoot Saddler down. This proves futile, so Ada resorts to shooting red barrels, all exploding on top of Saddler, this also proving futile, forcing Ada to directly fight Saddler.

Ada loses the fight, as the next time Leon sees her, she's tied up and hanging outside. Saddler left her alive as bait. Leon throws Krauser's knife through the rope suspending her, cutting it so that Ada fell onto a tarp below. Saddler laughs at the Hollywood-esque nature of the scene, then mutates further to fight Leon once again. Ada flees at Leon's insistence, although she zips around the battlefield to make her way to a platform with a rocket launcher. Once she reaches it, she throws it down so that Leon can use it. Leon fires the rocket, killing Saddler, who drops the sample Ada has been searching for. Leon picks it up, and Ada holds a gun to the back of his head, taking it from him. Ada runs and leaps over the edge, landing on a waiting helicopter. She tells Leon he better get off the island before pushing the timer of a bomb, surprising Leon that she actually pushed it. Before leaving, Ada tosses Leon the keys to a jet-ski located beneath the island. As Leon and Ashley make their escape via the jet-ski, Ashley flirts with Leon about doing some "overtime", which Leon politely declines. Ashley admits she somehow know Leon would and asks about "that woman". Leon answers, "She's like a part of me I can't let go. Let's leave it at that".

Resident Evil: Damnation
 In 2011 Leon and Ada meet during a mission in the Eastern Slav Republic, where Leon was reportedly sent as a soldier to stop the use of Biological Weapons in the civil war. Ada, meanwhile, would infiltrate posing as a BSAA Agent, also wanting to find out information about the Weapons Biological B.O.W.s.

The two meet when Leon decides to investigate a weapons delivery and Ada approaches him in the classic way, attacking him with her weapon. The two enter into a quick hand-to-hand fight until Leon realizes that he is attacking Ada, then ceases and begins to interrogate her trying to find out what she is doing there. Ada, ever unwilling to answer questions, replies that she is just "helping them", although she never clarifies who "them" is, and refuses to answer Leon's following questions. Instead, she asks Leon when they would "carry on from where [they] left off that night", to which Leon replies that anytime other than right then would be fine. Ada states that Leon is mad at her but decides to end the conversation and leave through the roof, telling Leon that the city they were in would be bombed soon. Leon watches her go, shaking his head and repeating his "Women..." phrase.

In the next scene with Ada, Svetlana, the villainous President of the country, asks her about not being at the hotel last night, to which Ada replies saying that she left to find an old friend, making the President believe that she was with an enemy, accusing Ada of being a Russian spy. The two begin fighting, which ends with Ada defeated and kidnapped. In the meantime, Leon infiltrates Bekova by gathering information from the soldiers about the underground facility, not knowing that was where Ada was being held.

Leon sees Ada in the Bekova underground facility and follows her. As Leon approaches, he jokes that Ada missed him, to which the woman replies sarcastically "Yeah... In your dreams". Together, the two begin investigating the Las Plagas storage room, exchanging the information they had about the virus, demonstrating that although they don't always work together, the two feel very comfortable with each other. Ada begins to steal information leaving Leon suspicious of her intentions to which she replies, "I'm working, don't worry about it". Svetlana's forces invade the room, cutting off their conversation. Upon being asked who Leon is, Ada replies that he is just an American agent, to which Leon complains saying "Well now that we got that out of the way..." as if he was upset by her response. Ada warns Leon to be careful with Svetlana, leaving him surprised, while quickly turning off the lights, to which Leon responds by firing at multiple locations in the crowd of soldiers, prompting them to shoot each other while the duo escape.

Soon after, Leon enters a confrontation with a president, although she escapes making Leon comment that Ada was right to warn him about Svetlana's capabilities. During the final fight, Leon situation becomes a matter of life and death. When Ada finds out, she quickly hacks the system to open a door, giving Leon an escape, stating that he owes her one, continuing their game of keeping score over who saves who.

Resident Evil 6
 In 2013, Leon and Helena Harper are partners working together to solve what caused the Tall Oaks outbreak. While down underground in a massive facility, Leon finds a tape labelled "Happy Birthday Ada Wong". Confused, he plays the tape and witnesses a woman emerge from a large cocoon, looking a lot like Ada. Angry, Leon turns to Helena and demands to know if that was what she wanted to show him, although Helena is just as confused and shakes her head. She instead asks Leon if he knew the woman in the video, to which he responds that he won't answer her unless she tells him what's going on. Helena opts to not answer him.

They then find Deborah, Helena's sister, unconscious and carry her through the facility until she encases herself in a chrysalis. As Deborah slowly emerges from her encasement into her mutated form, Ada shoots an arrow from her crossbow straight into Deborah's head, leaving Leon and Helena stunned as to why Deborah was thrown back so suddenly. Leon turns to Ada, confused, to which she responds "You look like you've seen a ghost". Filled with sorrow and rage, Helena raises her gun to shoot Ada, but Leon gently lowers the gun away from Ada's face. Leon demands Ada tell him what's going on to which Ada simply answers, "It's complicated". Seconds later, the place begins to collapse with Ada noting that "this isn't the time or the place". Deborah fully mutates, spouting new appendages and a battle ensues against her with Leon and Ada teaming up again. After the initial fight, and being knocked into an area further underground, Ada gives Leon a ring, telling him not to get the wrong idea, and that it'll make sense later. The pair continue to fight Deborah with Helena, moving constantly to avoid being trapped in the collapsing facility. After finally defeating Deborah, Ada vaguely explains the situation to Leon and Helena, although she is interrupted by her phone ringing. Ada grapples out of the area and away from Leon, finally answering the call from Derek C. Simmons, the man responsible for Deborah and U.S. President's death. Leon looks on after her, though says nothing.

Ada then begins working her way through the facility, coming across the video tape that Leon and Helena watched earlier. Surprised, she now realizes why Leon is so confused, and receives another call from Simmons. This time, however, Ada realizes that she is not speaking to Derek but to a doppelganger of herself created by him. She's quick to end the conversation and makes a brief call to the real Simmons to inform him about his little creation's plans to destroy the world, meeting Leon again in China.

Although both end up in China, they don't encounter each other for a while. While trying to find Simmons, Leon and Helena encounter Ada in a medical testing laboratory and spend some time chasing her through it alongside Chris Redfield and Piers Nivans, who are chasing her for a different reason. None of the four know that the woman they are chasing is not actually Ada, but her doppelganger. After Chris and Piers corner her, Leon attacks Chris to prevent him from shooting her. After a brief fight that results in the two drawing their guns on each other, Leon tells Chris that he's willing to protect Ada, even after learning she was working for Neo-Umbrella. While "Ada" is able to escape by throwing a flashbang at the group, Leon is able to convince Chris not to kill her and the group go their separate ways.

Entrusting Ada's safety to Chris proves a mistake, as the next time Leon hears about her, it is Chris telling him that she is dead. Although it was her doppelganger that died, Leon hangs his head in silence at the news of her death, believing it to be Ada that died. He eventually responds with a quiet "Copy" then goes into a basic fight-or-flight mode to focus on making it out of the infected city. Leon remains noticeably quiet and distraught during his and Helena's fight through the city, until the two are cornered in a street amongst dozens of infected.

Meanwhile, Ada has managed to get ahold of a helicopter, and has been flying through the city observing the destruction that her doppelganger caused in her name. While looking around, she spots Leon corned and, seeing him in trouble, shoots any closing-in zombies with the gun on her helicopter, allowing him and Helena a chance to run. For his part, Leon notices from the street that Ada is piloting the helicopter and is shocked yet relieved to see her alive, remarking that he thought she was dead. A short time later, Leon and Helena meet Simmons, who had been infected and mutated with the C-Virus. Ada flies over them in her helicopter, assisting in the fight that begins as Simmons mutates further until he is eventually downed. With the fight over, Leon and Ada share a look before Ada flies up. Leon watches her go, concluding she's heading for the roof of the tower.

On the elevator ride up to the roof, Leon is quiet. Helena breaks the silence by discussing Ada, saying "She's more than just a friend, isn't she? You have feelings for her". Leon says nothing, though gives a small smile. An explosion interrupts their conversation, knocking the elevator out and forcing Leon and Helena jump out, landing on a lower elevator. Moments later, that elevator gives out, leading to them jumping to grab the cable that elevator snapped from. As they're climbing, they spot Simmons and Ada battling on a sky bridge. They momentarily jump off onto a platform to help Ada, but it gives out and they are forced back onto the cable.

Noticing Leon on the cable, Simmons abandons his fight with Ada to kill Leon, something that Ada comments on. She helps Leon by shooting at Simmons and preventing him from closing in until Leon can get to safety. However, Simmons takes note of Ada's interference and abandons Leon in favor of fighting her again, knocking her down and leaving her unconscious and vulnerable. Leon sees this and decides to jump down from the cable, rushing to help Ada.

He cradles her in his arms, protecting her as Simmons advances towards them, and occasionally speaking to her in the hopes she would wake up. Simmons prepares for an attack, leading to Leon bending over and shielding Ada's body with his own against the attack. Ada comes to shortly after, commenting that she was "just resting her eyes". The two stand up and work together at battling Simmons, with Leon asking about any supposed history between her and Simmons that Ada responds to as nothing worth noting. Simmons is eventually able to knock Leon off the edge of the sky bridge, with Leon holding on by his fingers. As Simmons stands over him, kicking his hand away and trying to make Leon beg for his life, Ada comes from behind, stabbing him with one of her arrows and taking both him and her over the edge with Ada using her grappling hook to prevent herself from falling into the fire.

Safely on the other side, Ada and Leon look at each other, with Leon still confused about Ada's situation and Ada amused by Leon's confusion, stating that his confusion is cute. She then sends him a text about a "parting gift on the roof" and says that she'll see him down the road, turning away with a wave as Leon calls after her. Helena, witnessing everything from a safe distance, tells Leon that he should go after Ada, though he decides to stick with Helena, knowing that Ada had her own ways of getting out of the city.

On the roof, Leon and Helena spot the helicopter Ada was using earlier, which she had left for them as an escape route. Still, they aren't able to immediately reach it and must fight Simmons again on the rooftop. When they eventually make their way to the helicopter, Leon finds a rocket launcher leaning against it, a red kiss mark on the rocket, and uses the rocket launcher to defeat Simmons for good. Inside the helicopter, Ada had left a compact with a chip of evidence proving Leon and Helena's innocence as Simmons had tried to have them take the fall for the U.S. President's death.

Sometime later, after their innocence had been established, Helena gives Ada's compact back to Leon, telling him to give it back to Ada the next time he sees her.

Behind the Scenes

 * Damnation Scriptwriter Shōtarō Suga suggests that Leon and Ada had an off-screen romantic encounter while Resident Evil 5 (2009) was ongoing, more accurate, he did say: "romantic dinner/hotel/motel room night". There was not enough time in Resident Evil: Damnation to explore their relationship as Shōtarō had planned, so he left an "open window" for fans to "interpret it as they want". He did confirm that it was somewhere around RE5, and that the line was not a reference to any past games.
 * During a commentary playthrough for Resident Evil 2 (2019), Nick Apostolides (Leon's English VA) spoke about the voice direction he received during the scene in Umbrella's laboratory where he confronts Ada. Up until the final take, he was told to say, "Tell me you love me." between every line in order to draw out the emotional vulnerability the director was looking for.
