Alexander Graham Bell is a name that often comes up when we talk about groundbreaking inventions and the pioneers of modern communication. Most people recognize Alexander Graham Bell as the inventor of the telephone—a true icon in the history of science. But beyond textbooks and history lessons, Alexander Graham Bell also steps into the world of anime as a memorable character in Time Travel Girl (Time Travel Shoujo: Mari Waka to 8-nin no Kagakusha-tachi). In this charming series, Alexander Graham Bell isn’t just a historical footnote—he’s brought to life as a warm, inspiring mentor to the main character, Mari Waka.

As Mari journeys through time to explore pivotal scientific milestones, she crosses paths with several legendary figures, and Alexander Graham Bell stands out among them. He welcomes her with kindness and curiosity, embodying the spirit of a dedicated scientist who’s passionate about sharing knowledge. Alexander Graham Bell takes great joy in showing Mari his latest inventions, like the telephone and the lesser-known photophone, explaining their mechanics with genuine enthusiasm. There’s even a playful side to him—sometimes he hides behind his gadgets just to surprise Mari, proving that brilliance and humor can go hand in hand.

Despite his fame, Alexander Graham Bell remains humble throughout the series. He listens more than he boasts, always eager to learn from others while gently guiding Mari on her journey. What really defines his character, though, is his relentless drive for discovery. Alexander Graham Bell is portrayed as someone who never stops asking questions or pushing boundaries, constantly seeking ways to improve technology and deepen understanding. That kind of dedication leaves a lasting impression on Mari, reinforcing the idea that passion and perseverance are key to making a difference.

In many ways, Alexander Graham Bell serves as both a teacher and a symbol within the story—an emblem of innovation, intellectual courage, and quiet determination. The anime does a wonderful job humanizing him, making his legacy feel accessible and relatable. Through these thoughtful portrayals, Alexander Graham Bell becomes not just a name from history, but a living presence whose influence continues to inspire.

Now, if we take a closer look at his personality, especially in how he behaves throughout Time Travel Girl, it’s easy to see why many would classify Alexander Graham Bell as an INTP—Introverted, Intuitive, Thinking, Perceiving. He’s deeply reflective, often lost in thought while tinkering with machines or testing new theories. His mind thrives on logic and analysis, and he approaches problems with a calm, methodical precision typical of the INTP type. While he may seem distant at times, especially when absorbed in his work, Alexander Graham Bell still shows warmth and care, particularly toward Mari. It’s a balance between intellect and empathy—one that makes his character all the more compelling.

Looking at another layer of personality, Alexander Graham Bell also fits the profile of an Enneagram Type Five, known as “The Investigator.” This type is defined by a thirst for knowledge, a preference for solitude, and a desire to understand the world on a deeper level—all traits clearly reflected in Alexander Graham Bell’s demeanor. He tends to retreat into his research, sometimes appearing detached during social interactions, not out of coldness, but because his focus lies in comprehension rather than connection. His motivation seems rooted in a fear of inadequacy, driving him to constantly expand his expertise and avoid situations where he might feel vulnerable.

Of course, personality types aren’t meant to box people in—they’re tools to help us better understand motivations and behaviors. And while no label can fully capture someone as complex as Alexander Graham Bell, the portrayal in Time Travel Girl certainly highlights qualities consistent with both the INTP and Enneagram Five archetypes. Whether you’re drawn to his inventive genius, his gentle mentorship, or his introspective nature, one thing is clear: Alexander Graham Bell remains a fascinating figure, not only in history but also in storytelling.
