Ajim

Ajim is the het ship between Jim Lake Jr. and Aja Tarron from the Tales of Arcadia fandom.

Trollhunters
To make up for the days of school he missed, Señor Uhl assigns Jim to show Aja Tarron and her younger brother Krel around town, even though Jim and his friends need to collect some items for Merlin, he decides to merge the two tasks together. When the trio first take the siblings to the Janus Order, to collect dead Changeling bones, Jim tells them that it is a "top, secret teen-center", and after they notice that Krel is nowhere to he seen Jim asks Aja where he went to, they find him in the monitoring room where it shows security footage of Jim's battle to the fake Gummar. Luckily Aja thinks that they are seeing is a "moving picture story" and because they spent too much time in the underground liar, Jim and the others take Aja and Krel to Claire's house as the next stop on their tour.

After Aja hears Jim say that he and Toby are trying to catch lighting in a bottle, she and Krel lend the trio their assistance, while Krel turns a glass jar into a lightning catcher Jim and his friends watch Aja hack into the town's power grid so she can supply them with a lightning-like power source; without the need to wait for a thunder storm. To make sure that it gets into the bottle Jim changes into his armour, that Aja became amazed at as she asks him what the power source for it is while taking a close look at his amulet, before Jim sets his sword into the ground and ducks for cover with the others. Once they got the final item on the list, Jim thanks Aja and Krel for their help, as they couldn't have gotten it without them, and hopes that they'll be able to see each other again during the summer. Before the siblings parted ways with their new (odd) friends, Aja tells them that they'll probably see them again at the teen center.

Part One
Part one takes place during the events of part three of Jim's story, Trollhunters.

Originally, Aja first met Jim when they bumped into each other during a science fair in "D'aja Vu". Before they met on that day, Jim and his allies were chasing after the Trickster Troll named Porgon, who finds a piece of Akiridion tech that fell from the Mother Ship when the Tarrons came to Earth, and uses it with his magic to escape from Team Trollhunters all while affecting the space time continuum. By resetting time. Jim was the only one who remembers the days he relives through as they lead to the day of the science fair, where bumping into Aja was the only new thing that happened to him on that very day. When Porgon attacks the fair and Jim was about to use his amulet Aja gets out her shield to protect him from the troll's attack. Before Aja charges at the troll Jim stops her so he could ask Aja about the blue colored item in her hand, before Porgon resets the day. Just as a confused and frustrated Aja is about to leave the build, again, Jim pulls her aside so he can ask Aja for her help, based on the strange item that summoned the "bubble thing", and is relived to know that she also remembers the time loop. Due to the shield that the Serrator gives Aja, as she uses it each time Porgon creates a time jump back; while Jim believes that the power of his amulet could be what is protecting his memories of the time loop. At their next encounter, where Aja nearly attacks Jim with her Serrator in its blade mode she asks him what is happening. Jim promises to explain once she tells him what Akiridion tech. Aja answers Jim's question when Porgon attacks the building again, along with revealing her true Akiridion form to Jim when he asked her how she knows this. Jim is stunned by this but didn't have time to dwell on it as Porgon was about to use his magic on the piece of alien tech again, and the two needed to protect their memories of their most resent shared discussion.

To save time Aja goes to Jim's house, in her Akiridion form, so they could have time to form a plan of attack. Aja was worried that Jim is put off by her true form from how he reacted and is a bit speechless at the sight of her, but Jim's time with trolls and magic has him reassuring Aja that he thinks that her true self is really cool and she thanks him for his kind thoughts. Jim then calls his friends as they will need their help, after they explain the time loop and each others big secrets of Trolls and Aliens in Arcadia. When Jim and Aja's metros and warrior trainers, Blinkous "Blinky" Galadrigal and Varvatos Vex, had attacked each other until their young trainees reassured them, as well as AAARRRGGHH!!!, that they can trust one other. From within the Observatory Porgon was provoked into making another time jump back, luckily Jim gets Aja to summon her shield so all of their memories can be protected. Now that both Jim and Aja's parties are aware of the time loop and what is causing it, they meet at the Tarron's house so they could form a plan to defeat, but with Aja still not understanding the true main reason for combat patience had dash off to take Porgon on her own. This upsets Jim as he had a pretty good idea what the results of her charge in actions would be. After the day was reset, again, Jim and his friends regrouped at her house where Jim gives Aja a disappointing look that gets the Akiridion to apologize for her actions before she tries to leave the house in order to try her attack attempt again, but Jim stops her from doing so. As they will need to take on Porgon together as a team with a plan. Jim tells Aja as a fellow warrior of the none patient choice he had made when he went into the Darklands alone and the main reason that he didn't remained trapped there was because of his friends, along with it teaching him why he should have been patient at the time. This has Aja sharing her reasons why she can't be as she expresses her pain over what had happened to her and her family before they came to Earth. Jim felt sorry for Aja and her brother, as he knows that a lot of surviving trolls are going through something similar when they were forced to flee from Trollmarket; but doesn't share this with Aja since Krel was already there to comfort his sister on the subject.

Now that they finally have a plan to defeat the troll, Jim, Aja and their friends head to the Observatory so they could set the stage that would allow them to trick the trickster troll, once everything was set Jim puts on his armour and it amazes Aja and Krel as they too want an amulet that gives them armour. While they were finally able to defeat Porgon and get the Akiridion tech away from him before the troll could make another time jump, their actions inadvertently exposed their biggest secrets to a large crowed of people and the police that were called to the scene. With little options, Krel comes up with the idea of making another time jump that would have the piece of tech destroy itself before Porgon could find it on the night Team Trollhunters had failed to catch him, but it would mean that the repeating days would never have happened and the friendship that Jim and Aja had formed during them would be gone and forgotten, which saddens the both of them. Blinky, however, reassures them that while their friendship will be forgotten it will still be there and that it will have fate bring them together again. Even though the reset the time line has changed and either of them have any memories of the repeated day or each other, a small part of what Aja learned from Jim about patience had somehow stayed with her. Along with Aja bumping into Jim at the science fair, as it mirrors their original first meeting.

The two met again in "Lightning in a Bottle", where it shows Aja's end of events in the Trollhunters episode "In Good Hands", even though are there many differences between the two episodes due to the lack of action with Aja and Krel in Trollhunters; compared to them in 3Below. As Aja searches for her dropped serrator in the forest she sees Jim from afar and mistakes the similar blue glow from his Amulet of Daylight as the emanating light from her lost weapon, and because she is in her non-human form Krel stops her from approaching Jim in order to retrieve her serrator. The next day Aja sees Jim at school and works on a plan to retrieve her weapon from his bag, before she and Krel were called to Señor Uhl's class where the said teach tasks Jim to show the two around town. During their tour, Aja tries many times to get her "serrator" back but Jim had caught her eyeing his bag, along with a few other events that prevent Aja from searching it. In the end Aja realizes that Jim and his friends never had her serrator and the review mirror of the car Jim hid behind shows Aja the magical armour that Jim's amulet placed upon him. Aja and Krel's time Jim, Claire and Toby had that day also taught them that being weird can also be cool. When Aja parts ways with Jim she calls him and his friends Trollhunters.

Much like how "Lightning in a Bottle" is of the 3Below side of events during "In Good Hands" in Trollhunters, "Last Night on Earth" is of Aja's side of the story during "The Eternal Knight: Part 1" (the same with "Bad Omen" during the events of "The Eternal Knight: Part 2"). Shortly after the Gumm-Gumm Army attacks Arcadia, Aja sees Jim arriving to help his friends after he sliced the thrown van and despite his new Troll appearance, she knew that it is him. Since his "safety suit" was a big give away and his new troll face wasn't too different from his former human face, along with the memory of the moving picture story of Trollhunters revealing the title he carries and the hidden world he is connected to. Aja had wanted to stay and help the people of Arcadia, after seeing Jim's friends fight the Gumm-Gumms, but before she and Krel could join in to help them the Mother Ship was being attacked and needed them to return back to the said ship before anything bad happens to their parents.

Part Two
Part two of 3Below takes place sometime after Jim had left Arcadia with the rest of its trolls, and even though he and Aja don't interact with one another, in person, during the second part of her story, Aja does hear a few things about Jim from his friend Toby.

When Aja and her allies needed to get into Trollmarket, so they could retrieve Gaylen's Core before General Morando does in "Race to Trollmarket", Toby gets her and Krel in contact with Jim and Binky in hopes that they'll be able to tell them where Kanjigar could have hidden it. Because of the battle that Jim is fighting on his end, he only had enough time to give Aja and Krel a quick "how's it going?" hello after Aja gives him a acquired "Hi". As they were both in a hurry and the moment of the call was a little acquired to replay and watch/answer. Like Jim was in "D'aja Vu", before their shared memories of one another were erased, he didn't seem to mind the (relearned) fact that Aja and her brother are Akiridions, since his smile to them in the call hints that he still sees them as the friends he had made in "In Good Hands"/"Lightning in a Bottle".

Rise of the Titans
After Jim gets hurt on a failed attack on the Arcane Order, Aja return to Earth so she can help her friends fight them. Because the state Jim is in from losing the Amulet of Daylight, Aja wasn't fully sure if he still has what it takes to be the Trollhunter and offers to have her people's fleet get everyone off Earth, before the Titans destroy the Earth. Jim on the other hand, still wants to fight despite the odds and this gets Aja to agree with helping them fight. While still having her plan as a last resort.

Quotes
"The truest of friendships have the power to trancend both time and space"

- Blinky to Jim and Aja in "D'aja Vu"

Fanon
The friendship the two formed in "D'aja Vu" and both being sad about the fact that they have to change the timeline in a way that would prevent them from meeting or remembering each other, just so they could maintain their secrets, could have started the ship. As well as the fact that both Jim and Aja have gone through warrior training under their mentor-trainers, carry around blue, glowing objects that provides them with a sword and have a non-human form that gives them blue colored "skin". Aja's true alien/Akiridion form and Jim's human-troll form. Most fanart of the ship commonly has Jim and Aja in those said forms, then to have both or just one of them as their human selves. This ship has also been rivalled with Jlaire and Staja. Along with the release of Wizards inspiring fans to ship Ajim beside Douxaire.

Ajim fans were upset when Aja didn't return in Wizards to help Jim, but are hoping that she does in the upcoming film that will serve as the final chapter of the Tales of Arcadia series. So Aja and Jim could have the chance to rebuild the friendship they formed in both "D'aja Vu" and "In Good Hands"/"Lightning in a Bottle".

On AO3, the ship only has 12 fanfics.
