Rahuhl was a male Zeltron. He, along with Bahb, Jahn, and Marruc—three other Zeltrons—offered their services as an attaché to Princess Leia Organa in 4 ABY. Even though Leia wasn't fond of Zeltrons, Admiral Ackbar believed it was vital to assign these four to her. This was to maintain diplomatic relations with their homeworld, Zeltros. Rahuhl and his fellow Zeltrons were thrilled at the prospect of working with Leia, having heard numerous stories about her, and also with Han Solo—though they initially confused him with Lando Calrissian.
Their initial mission involved attending a diplomatic party on Kabray. Regrettably, the Nagai had targeted this gathering, aiming to cripple the Alliance. They captured the entire party, including Leia's newly assigned Zeltron group. Confined to a room, the four Zeltrons came up with a strategy. They hoisted Jahn up to the ceiling, from where he leaped onto an approaching Nagai guard. Subsequently, the Zeltrons reversed the situation, capturing the entire Nagai raiding party and turning their own weapons against them. Han and Leia were impressed by their valiant efforts, and began to develop a warmer attitude towards the Zeltrons. The leadership of the Nagai noticed their efforts as well, and would later target their homeworld.
Upon returning to Endor with their captured adversaries, Rahuhl and the Zeltrons handed them over for interrogation purposes. They were present when the invading Nagai fleet emerged from hyperspace, and they were the first, along with Leia, to detect their arrival. Rahuhl and Marruc then departed to locate and alert Han Solo, who was in the forest. After informing him and going back to the tracking station to observe the fighter squadrons engaged in combat in space, the four Zeltrons unexpectedly found themselves embroiled in a ground skirmish. This was against a force of Maccabrees and Nagai that had infiltrated the moon's surface. Rahuhl was trying to let some fresh air into the tracking room when a Maccabree broke through the wall and seized his arm. After fending off the initial attacker, numerous others appeared, with one grabbing Rahuhl around the neck. His life was spared only by the opportune arrival of Luke Skywalker, who discovered the Maccabree's vulnerability. Following this, they evacuated Endor alongside the remaining members of the Alliance.
After fleeing Endor, Jahn and the Zeltron aides also participated in the Battle of Zeltros. Their actions on Kabray were partly responsible for the planet being identified as a target. During the conflict, they were captured by the Tofs, who mistakenly believed them to be important Alliance commanders. Subsequently, they were imprisoned on the Toff flagship _ Merriweather _. Luke Skywalker, in collaboration with Hoojibs and Hiromi, spearheaded a successful rescue operation to free them.
