Gelmud is a character you definitely can’t overlook in the anime That Time I Got Reincarnated as a Slime, also known by its original title Tensei Shitara Slime Datta Ken. Right from the start, Gelmud stands out as a major player in the story, shaping key events and influencing the direction of the plot in significant ways. And honestly, if you’re following the series closely, you’ll notice just how much impact Gelmud has—both as a schemer and as a force of disruption.

Now, when we talk about Gelmud, it’s important to recognize that he’s one of the main antagonists. He isn’t just some random villain; he’s someone with deep intellect, long-term plans, and an almost obsessive focus on achieving dominance through magic and manipulation. Gelmud, as a powerful wizard, doesn’t rely on brute strength—he uses his mind. His entire goal revolves around world domination, and he’s willing to go to extreme lengths to make it happen. In fact, Gelmud is the mastermind behind the whole plan to create a demon lord whose rise would plunge the world into chaos. That alone shows just how far ahead he thinks compared to others.

Visually, Gelmud cuts a striking figure in the anime—pale, long hair, dark clothing, and this eerie aura that practically screams “danger.” He positions himself as a counselor to the demon lord, offering guidance and support, but make no mistake: Gelmud is pulling the strings behind the scenes. He manipulates her growth, using her power to serve his own hidden agenda. It’s classic Gelmud—always two steps ahead, always working toward his ultimate vision.

And while Gelmud may be on the side of darkness, you’ve got to give him credit for being genuinely formidable. He’s not just evil for the sake of it; he’s intelligent, resourceful, and deeply knowledgeable in arcane arts. This makes him a serious threat to Rimuru Tempest, the protagonist, who eventually has to confront the kind of calculated evil that Gelmud represents. In many ways, Gelmud symbolizes the kind of oppressive, controlling force that must be overcome for true peace to take root in this fantasy world.

When we dive into personality types, Gelmud fits the INTJ profile pretty well. If you’re familiar with Myers-Briggs, you’ll know that INTJs are strategic, analytical, and often operate like chess masters—exactly like Gelmud. He plans meticulously, anticipates outcomes, and rarely acts without a purpose. Plus, he’s extremely confident—some might even say arrogant—especially when dealing with those he views as beneath him. But here’s the catch: Gelmud’s obsession with control and his rigid worldview sometimes blind him. That overconfidence? It ends up becoming one of his biggest weaknesses, contributing directly to his eventual downfall.

Looking at things from another angle—the Enneagram—Gelmud strongly aligns with Type 8, the Challenger. This type thrives on power, autonomy, and control, which perfectly describes Gelmud’s motivations. He doesn’t just want influence; he wants to dominate. He’s not afraid to use force or intimidation, and he takes charge whenever possible. Underneath all that aggression, though, there might be a deeper fear—fear of vulnerability, fear of losing control. That’s a common trait among Type 8s, and it adds a layer of complexity to Gelmud’s character.

Sure, Gelmud does a lot of terrible things, but you can’t deny that he also has traits people might admire—like resilience, decisiveness, and the ability to stay composed under pressure. These are all hallmarks of a Type 8, even when they’re used for questionable ends. So while Gelmud is undoubtedly a villain, his personality is layered, driven by both ambition and inner fears.

Of course, personality typing isn’t an exact science. People—even fictional ones like Gelmud—can show traits from multiple types. But based on his actions, decisions, and overall behavior throughout That Time I Got Reincarnated as a Slime, Gelmud lines up most clearly with Type 8. His relentless pursuit of power, his commanding presence, and his need to stay in control all point in that direction.

All in all, whether you love him or hate him, Gelmud remains one of the most intriguing figures in the series. From his role as a manipulative strategist to his psychological depth, Gelmud proves that villains can be more than just obstacles—they can be complex, compelling, and unforgettable. And in a world full of monsters, magic, and reincarnated heroes, Gelmud still manages to stand out.
