ZekeLena

ZekeLena is the het ship between Zeke Jaeger and Yelena from the Attack on Titan fandom.

Canon
Yelena and Zeke have a type of idol-fan relationship. She regards him as a god since she saw him for the first time after he saved her life during the Marley Mid-East War. She follows his commands without question, believing he is the one to save the world. As she works with Zeke, she and the other members of the Volunteers are notified by Zeke of his half-brother Eren, who has possession of two Titan abilities. Expressing a desire to see him, Yelena volunteers to go to Paradis Island as part of the crew serving aboard a survey ship.

During her time in Paradis Island, she meets up secretly with Eren. At about the same time, Yelena began distancing herself from the other Volunteers and arranged with Zeke to have numerous bottles of wine mixed with his spinal fluid sent aboard the survey ships to Paradis. This is something not even Onyankopon, one of the closests to her from the Volunteers, knew about. She meets with Niccolo and tells him the wine being brought in is to be distributed and given to all those in the military, especially the more senior members and leaders.

After the military's officials learn that they have unwittingly been drinking Zeke's spinal fluid, many of them defect to the Yeagerists so that they will not be turned into Titans. As a result, Pixis is forced to surrender unconditionally to the Yeagerists, and is brought to speak with Yelena. She tells him that if only they had trusted Zeke from the beginning, they would have saved the world by now. And rectifies that Zeke is the god who will save the world.

She is so faithful of Zeke, without questioning once. To the point that, even after he was defeated and betrayed by Eren, she still thinks his plan would've been the only way to solve the two-thousand-year-old Eldian problem. She even makes Hange admit this in exchange for key information on Eren.

Fanon
ZekeLena is a very rare ship in the Attack on Titan fandom. This has to do with the fact that the two of them don't have many interactions throughout the series. Also, many people consider their bond to be more of a fan-idol, than a romantic one, so the ship is not perceived as a "romantic" one. It's also overshadowed by Yelena's most popular ship, Pikulena.

The ship currently has only over 40 works on AO3.
