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 collects 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 they find him to 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 saying that he and Toby are trying to catch lighting in a bottle, she and Krel led the trio their assistance, while Krel turns the bottle into a lightning catcher Jim and his friends watch Aja hack into the town's power grid so she can supply them with the lightning; without the need to wait for a 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 is while taking a close look at his amulet, before setting his sword into the ground and ducking for cover with the others. Once they got the final item on the list, Jim thanks Aja and Krel for their friends, as they couldn't have gotten it without them, and hopes that they'll be able to see them 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

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, Porgon, the troll finds a piece of Akiridion tech, that fell from the Mother Ship when the Tarrons came to Earth, and uses it to escape from them all while affecting the space time continuum. By resetting time. Jim was the only one who reminders 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 attacked and Jim was a about to use his amulet, Aja gets out her shield to block the troll's attack, Jim asks her about it before Porgon reset 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 "bobble thing", and is relived to know that she also remembers the repeat. Due to the shield that her Serrator gives her, as she uses it each time that 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 had nearly attacked Jim with her Serrator in its blade mode, and Porgon attacks the building again, Aja explains that the Troll is holding a piece of Akiridion tech and the reason that she knows this is because she is original from there, before she shows Jim her true form. Jim is shock by this, but didn't have time to dwell in it as Porgon was used to use the alien tech again with his magic, and the two needed to protect their memories of their discussions.

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 he reassures Aja that he thinks that Aja's true self and form is really cool, before he 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.

Part Two

When Aja and her allies needed to get in 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.

Part One
D'aja Vu
 * They show each other the blue colored items that are protecting their memories.
 * Even though the time line has changed and they have no memory of the repeated day or each other, a small part of what Aja learned from Jim about patience had somehow stayed with her.

Part Two
The Big Sleep
 * When Aja had saw Kanjigar in her parents' memories, she knew right away that he was the Trollhunter before Jim.

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.

On AO3, the ship only has 12 fanfics.
