In the world of That Time I Got Reincarnated as a Slime, the name Geld refers to two distinct but connected characters. The original Geld, known as the Orc Lord, serves as a tragic antagonist before eventually being succeeded by another orc who takes on his name and becomes a loyal subordinate to Rimuru Tempest and a key figure in the nation of Tempest.

The original Geld was a massive orc who rose to power during a great famine that threatened his entire tribe with extinction. Situated in a harsh environment, the orcs faced a starvation crisis that pushed them to desperate measures. Geld was named and empowered by the majin Gelmud, whom he regarded as a father figure and mentor. This naming ritual, combined with his unique skill called Hunger, allowed him to evolve into the Orc Lord, a catastrophic existence that appears once every several centuries. Driven by a deep and sincere need to protect his people from suffering, Geld led an army of two hundred thousand orcs on a devastating march, destroying the villages of the ogre tribe and attacking the kingdom of the lizardmen. His forces consumed everything in their path, turning other monsters and living beings into food for their survival. Consumed by his role, Geld eventually devoured Gelmud himself, which caused him to evolve further into a Demon Lord Seed known as the Orc Disaster, granting him even greater power. In his final confrontation with Rimuru Tempest, the slime used his own unique skill Predator to consume Geld entirely. As he was being absorbed, Geld felt a profound sense of relief, believing that Rimuru would take on the burden of his sins and ensure the survival of his people.

The second character to bear the name Geld is a different orc who inherited the title after the original's defeat. This Geld is the new leader of the orc tribe who pledges loyalty to Rimuru. While he is a formidable warrior, his personality stands in stark contrast to his predecessor's desperate nature. He is depicted as an exceptionally hardworking, gentle, and nurturing individual. Despite his large and intimidating appearance, he displays a soft and patient side, frequently spending time with the young goblin children of Tempest, interacting with them kindly and protectively. He is known as one of the hardest workers in the nation, taking on responsibilities not only in battle but also in the construction and development of the city. As a member of the elite guard known as the Twelve Guardian Lords, Geld serves as a primary tank for the group. He is characterized by his incredible defensive capabilities, ultra-speed regeneration, and ability to nullify pain. In recognition of his hard work and loyalty, Rimuru rewards him with a set of legendary-class armor and a shield, which react to Geld’s own aura and significantly boost his defense to rival god-class equipment. His role in the story evolves from that of a defeated enemy to a trusted and essential member of Rimuru’s inner circle, embodying the theme of reconciliation and redemption for the orc race as a whole.
