Let’s talk about Mr. Osomatsu for a moment—a wildly popular Japanese anime that follows the chaotic, hilarious lives of six identical Matsuno brothers, each with their own distinct personality and quirks. While the spotlight often shines on the main sextuplets, there’s one character who quietly but meaningfully contributes to the show’s charm: Hatabou. Though he may not always be front and center, Hatabou plays an important role in Mr. Osomatsu, bringing both comic relief and unexpected depth to the series.

Hatabou is best described as a mischievous little troublemaker—always up to something, usually with a sly grin on his face. He looks like a tiny devil, complete with red skin, bat-like wings, and a pointed tail, yet he wears a clean white shirt and bright pink shorts that make him instantly recognizable. But honestly, it’s his eyes that really steal the show—yellow, glowing, and full of playful scheming. You can practically see the gears turning behind that mischievous gleam.

Now, here’s the twist: despite his demonic appearance, Hatabou isn’t evil at all. In fact, he’s quite the opposite. He’s actually a loyal companion to the Matsuno brothers, especially in moments when they need someone clever—or just someone willing to cause a distraction. Even though he’s small in stature, Hatabou has a massive presence thanks to his bold personality and quick thinking. He’s got a knack for turning any situation around with his wit, often surprising everyone (including the audience) with how resourceful he can be. It’s no wonder fans of Mr. Osomatsu have grown so fond of him over time.

When you really dive into Hatabou’s character, it becomes clear that he adds more than just laughs to Mr. Osomatsu. His antics are funny, yes, but they also serve a purpose—highlighting themes of loyalty, creativity, and even vulnerability. Whether he’s tinkering with gadgets or pulling off some wild prank, Hatabou brings a unique energy that sets him apart from the rest of the cast. And honestly, once you notice him, it’s hard not to pay attention. He might not be one of the six main brothers, but in many ways, he feels like an essential part of the Mr. Osomatsu world.

Looking deeper at his behavior, Hatabou seems to fit the INTP personality type—Introverted, Intuitive, Thinking, Perceiving. He’s quiet, thoughtful, and tends to keep to himself, which makes sense given how much he enjoys working on experiments and mechanical projects. He doesn’t follow rules blindly; instead, he uses logic and curiosity to navigate the world around him. This analytical side allows him to come up with creative solutions that others might overlook. Plus, his ability to think several steps ahead gives him an edge in tricky situations, making him a surprisingly reliable ally in Mr. Osomatsu.

His intuitive nature means he often sees things others don’t—like hidden patterns or underlying motives. That’s why his decisions sometimes seem unpredictable, even reckless, but they’re usually rooted in careful reasoning. And while he may appear detached at times, it’s not because he doesn’t care. On the contrary, Hatabou deeply values his relationships, especially with the Matsuno family. His perceiving trait also explains why he dislikes rigid plans and prefers to stay flexible, adapting as new challenges arise. All of this makes Hatabou not just a fun character, but a smart and complex one too.

Beyond MBTI, Hatabou also shows strong signs of being an Enneagram Type 6—the Loyalist. This fits perfectly with his devotion to Matsuzo, whom he sees as his boss and protector. He’s constantly looking out for the group’s safety, often going out of his way to prevent disasters before they happen. You can tell he feels a deep sense of responsibility, even if it leads to anxiety. In fact, Hatabou worries a lot—overthinking scenarios, fearing the worst outcomes, and seeking reassurance from those he trusts. These behaviors are classic signs of a Type 6, driven by a need for security and trust in uncertain environments.

Despite his fears, Hatabou never backs down when it matters. His loyalty runs deep, and he’ll step up whenever his brothers—or his boss—are in danger. That mix of caution and courage is what makes him such a compelling figure in Mr. Osomatsu. He’s not fearless, but he acts anyway, proving that bravery isn’t the absence of fear, but the choice to move forward despite it.

So, whether you’re a longtime fan of Mr. Osomatsu or just discovering the series, Hatabou is definitely a character worth noticing. From his quirky design to his layered personality, he brings something special to the table. And while the six brothers may carry the story, characters like Hatabou remind us that sometimes, the most memorable moments come from the ones who operate just outside the spotlight. In the ever-chaotic world of Mr. Osomatsu, Hatabou stands out—not just as a comic sidekick, but as a clever, loyal, and unexpectedly profound presence.
