EreGabi

EreGabi is the friendship between Gabi Braun and Eren Jaeger from the Attack on Titan fandom.

Canon
Gabi first learns about Eren while she watches Tybur's production along with her fellow Warriors and Warrior candidates. Then, she learns that Eren is one of the biggest threats to the World and that he is "a rebel against peace". So, understandly so, when Eren's Attack Titan comes forth to crush the stage, sending Willy's eviscerated corpse into the air and rubble hurling towards the crowd, and as she sees the horrendous deaths of her friends, she gets traumatized.

As the Survey Corps arrive and Gabi witnesses even more deaths, she grabs the rifle left by one of the fallen guards who were killed in front of her, and runs towards the plaza, where Eren has been trapped by the War Hammer Titan. Looking for Eren, with pure rage in her expression, Gabi runs towards the battle holding the rifle and declaring that she will kill him. She manages to get into the Survey Corps' airship and there she watches in horror that her Warchief, Zeke Yeager, is not only still alive (as she thought he died in battle), but also that right next to him, is Eren Jaeger. Gabi is unable to attack him, because she's frozen in place.

After this, Gabi is taken as a prisoner to Paradis Island, alongside Falco, but manages to escape, meeting the family of Sasha Blouse, the soldier she shot in the airship, who later on take her and Falco to a restaurant. There, after an incident with the Blouse family, she's taken to a back room, with Mikasa and Armin, and that's when she meets Eren once again. Eren arrives unexpectedly and Gabi sits with all three while they talk. She stays silent after hearing them discuss Eren's recent actions, nervously looking at Eren's sliced open hand. Gabi is shocked when Armin attacks Eren after he verbally abused Mikasa and watches the two briefly fight. As both Mikasa and Armin are ordered to be taken to Shiganshina District, Eren orders his followers to have Gabi taken as well.

In a prison cell in Shiganshina, Gabi sees Eren enters her cell accompanied by two guards in military uniforms. In exchange for saving Falco's life, he asks her to cooperate with him by making a radio call for help, which would make the Paradis infiltrators react. Gabi is overcome with fear and is unable to move. Just then, one of the guards stabs the other in the neck and points her gun at Eren. Gabi recognizes the guard as Pieck Finger, but is quickly silenced by her. Pieck orders Gabi to use the dead guard's rifle to hold Eren at gunpoint, but orders her to stand down once Eren correctly deduces that neither of them have the permission to harm him. To Gabi's horror, Pieck claims that she desires to join Eren in overthrowing Marley, and attempts to turn her gun on Pieck before being disarmed. Pieck agrees to show Eren where her comrades are hiding as a sign of her loyalty, and she and Gabi are then handcuffed together before traveling to the roof of the Yeagerist headquarters. Upon reaching the roof, Pieck shields Gabi as Galliard's Titan bursts from within the building to eat Eren. Gabi is overjoyed to learn that Pieck has not betrayed Marley, and is thrilled to see the Marleyan air force arriving over Paradis. Pieck has Galliard cut off her arm so that she can transform and uses her Titan form to flee to safety with Gabi, leaving Eren behind.

Gabi is shocked to learn that Falco has ingested some of Zeke's spinal fluid, which would turn him into a mindless Titan. So as Falco and his brother are confronting Zeke about Falco's predicament, Gabi arrives with a horse and tries to convince Falco to flee out of range of Zeke's scream with her. However, before she can get any closer, Zeke screams and Falco is transformed into a Pure Titan. As Falco attacks Reiner and Galliard, Gabi sees that Colt has been killed by Falco's transformation, and retrieves his anti-Titan rifle from his corpse. Gabi cries out for the lives of her friends, and focuses her rage towards Eren. She quickly points the rifle at him and fires a single round. Before the two Yeager brothers can reach each other, the bullet strikes Eren's neck and completely decapitates him.

Gabi flies backwards due to the recoil of the rifle and does not see Zeke catch Eren's decapitated head. When she hits the ground, Gabi notices the walls cracking as the Earth around her starts to rumble. Moments later, the walls begin to violently crumble as the Colossus Titans emerge from their core. Large pieces of the broken wall begin falling close to Gabi. When she looks up, Gabi is astonished to see a uniquely formed Titan skeleton growing from Eren's body in a huge burst of steam. Right after the commotion of the Rumbling, Gabi is at a crossroads in her life. She realizes that people living in Paradis are no different from themselves and begins fighting against Eren, who has become the true enemy of humanity, to save everyone.

Fanon
Eren and Gabi have a purely antagonistic dynamic, so it's hard to find a typical friendship dynamic aspect of their relationship. However, many fans love the pair because of its similarities, and how Gabi blatantly parallels Eren in the story. Both of them are children who grew up on different sides of a war. Both are determined to erase all of their enemies, believing to be able to save humanity that way. Both have an extraordinary rank, being the Attack Titan and the successor to the Armored Titan. Both of them shoulder a lot of responsibility for their side, but after coming in contact with the enemy, they have to deal with the fact that they, too, are just human. Both of them get to know both sides of the conflict. The difference is how they choose to face this situation. Eren decides to protect what is important to him, ignoring that the circumstances have changed. Gabi tries to adapt to the situation and tries to become a force for peace. Some fans of the friendship also view Eren and Gabi as siblings in AUs.
