|Oruo! Petra! For a couple of soldiers who cried and pissed their pants during their first battle, you've really grown!|
|— Eld teases his teammates|
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 most other Scout Regiment 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.
Eld was a responsible and firm leader with a strong sense of duty. He did not talk much, but when he did, he spoke bluntly and in a straightforward manner. He also seemed to have been a veteran of sorts as he teased Petra Rall and Oruo Bozad 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 Oruo that a kill record alone does not make a great soldier.
When Eren accidentally transformed, he 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; Oruo 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's transformation as he bit his hand just like Eren, which symbolized a bond between them.
Eld appears for the first time as a member of the Scout Regiment in year 850. During the expedition in the Titan territory, he and Gunther Schultz are the reinforcements gathered by Petra to aid Levi and the wounded soldier. These three soldiers are then shown to be surprised when Levi heads off to take care of two Titans on his own. The expedition is then soon cancelled as Erwin Smith notices the Titans moving towards the city, signalizing a possible breach.
On the 57th scouting mission, Eld and the rest of his squad travel with Eren and vow to protect him. Although they are nearly all killed by the Female Titan inside the forest, the Scouts manage to successfully capture it in a trap, which was a plan made by Erwin Smith in order to capture the spy, made possible because Eren decided not to transform and trust in his comrades. Afterward, 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 as one of the soldiers.
Afterward, the squad begins to retreat back to their horses, when a flare leads them off-course. They are ambushed by a person whom they thought to be Levi, but later revealed to be Annie Leonhart, who murders Gunther with the omni-directional mobility gear before transforming back into her Titan form in order to chase them. 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 Oruo to take out her eyes, then Eld launches several attacks on her arms before Oruo and Petra joined in, severing them and proving them useless.
As Eld and Petra move in for the kill, the Titan suddenly regenerates a single eye and bites Eld in half, also severing his arm. Eld's upper half is thrown to the ground as the Female Titan engages Petra and Oruo, killing them both while Eren looks on in horror.
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 omni-directional mobility gear, using fake-outs with the steel wires to propel himself backwards during an attack in combination with using the ODM 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 very skillful when using his blades to bring down the Female Titan's arms, as shown by him using a variety of different attacks.
