Eld Jinn

Eld Jinn (エルド・ジン) was the second-in-command of the handpicked soldiers of the Survey Corps by Levi to be included in the Special Operations Squad.

Appearance
Eld had brown eyes and long blond hair which had a middle parting and a bun folded at the back to keep his hair tied. He also had a small beard. He had small brown eyes and a serious face. Like many other Survey Corps members he wore a green cloak with The Wings of Freedom emblem on the back. He wore the same uniform as the other scouts and had a white shirt underneath.

Personality
Eld was a responsible and firm leader with a strong sense of duty. He did not talk much, but when he did, he talked bluntly and in a straightforward manner. He also seemed to have been a veteran of sorts as he teased Petra Ral and Oluo Bozado about having wet their pants on their first expedition, and sarcastically referred to them as "fine fearless soldiers". He also seemed to hold some sort of belief of what makes a true soldier, as he lectured Oluo that a kill record alone does not make a great soldier.

When Eren accidentally transformed, he also seemed to have been more concerned about the reasoning as to why and demanded an answer from Eren. His reaction was interesting in comparison to his comrades as Oluo threatened to kill Eren, Petra feared for Levi's life, and Gunther demanded evidence from Eren about his transformation and intentions.

Along with the other members of the Special Operations Squad, he had some remorse over his reaction to Eren when he transformed as he bit his hand just like Eren, which symbolized a bond between them.

The Female Titan arc
On the 57th Expedition, Eld, along with the rest of his squad travel with Eren and vow to protect him. Although they are nearly all killed by the Female Titan, the Survey Corps manages to successfully capture it in a trap, which was a plan made by Erwin Smith in order to capture the spy. Afterwards, the Special Operations Squad is ordered to standby while efforts are made to capture the human within the Female Titan. Meanwhile the Special Operations Squad members have a conversation in which they consider that there could be some kind of spy that actually wants to destroy humanity. However, the operation ends in failure when the Female Titan uses a scream to summon other Titans to her position and is devoured by them, allowing her human host to escape out of the body.

Afterwards, the squad begins to retreat back to their horses, when a flare leads them off-course. They are then ambushed by a person who they tought to be Levi, but later revealed to be Annie Leonhart, who murders Gunther Schultz with the 3D Maneuver Gearbefore transforming back into her Titan form again. Eren is ordered to flee while the surviving squad members engage the Titan in battle. Petra and the others initially seem to have the upper hand. Eld launches an attack and a smoke screen blinding the Titan,  that allows Petra and Oluo to take out her eyes, then Eld launches several attacks on her arms before Oluo and Petra joined in making them drop, making them deep cuts.

Eld and Petra move in for the kill, but the Titan suddenly regenerates a single eye and bites Eld in half, also severing his arm. Eld's half bitten body is then thrown to the ground as the Female Titan begins to engage with the remaining members with ease, killing them both while Eren looks the battle with surprised eyes.

The Uprising arc
While speaking to Historia under the Reiss chapel, Eren mentions Eld as being among the victims he and Grisha Yeager are responsible for killing by stealing the Titan's power.

Abilities
Eld was a very adept warrior who had a very high kill record of 46 Titan kills (of which 32 were with a team and 14 were solo). He also seemed to have been very proficient with the Maneuver Gear, using fake-outs with the steel wires to propel himself backwards during an attack in combination with using the Maneuver Gear to help him brake while simultaneously using the gas exhaustion as a smoke screen to blind a Titan and support his comrades' attack. He was also very skillful when using his blades to bring down the Female Titan's arms, as shown by him using a variety of different attacks. Due to the fact that
