Bíblia, also known in some versions as the Superbook, is a central character in the anime Superbook. This character is not a person but a large, ancient, and sentient Bible that serves as the primary catalyst for the series' adventures. In the original storyline, the book is discovered by the young protagonist Chris and his friend Joy while they are cleaning the attic of Chris’s home. From the moment of its discovery, the book is shown to possess extraordinary and supernatural qualities, distinguishing it from an ordinary religious text.

The background of Bíblia is that it is a mysterious and powerful artifact. When the children first find it, they are unable to open it through their own strength. The book, however, opens itself with a brilliant, dazzling light, immediately establishing its autonomous and magical nature. It is the device that enables the series’ core premise: time travel into the narratives of the Bible. Its primary motivation is to educate and guide its young companions by transporting them directly into the events of both the Old and New Testaments, allowing them to witness stories ranging from Adam and Eve in the Garden of Eden to the life of Jesus and the ministry of the Apostle Paul.

In the story, Bíblia functions as more than just a transport mechanism; it is an active, speaking guide and teacher. The book’s role is to provide context, answer questions, and ensure the children understand the moral and spiritual lessons of the historical events they witness. Its key relationships are with the main child characters, Chris and Joy, as well as their robot companion, Gizmo. While Gizmo gains the ability to walk and talk only when an adventure is underway, Bíblia is the source of that power and the director of their journeys, consistently leading them back to its pages for the next lesson.

Regarding character development, Bíblia remains a constant and wise figure. It does not undergo personal change but instead facilitates the growth of the children, teaching them how to apply biblical principles to their own lives. One notable ability attributed to the influence of the series is that it can teach viewers how to pray and that they can speak directly to God, as demonstrated by characters who learn prayer from watching the show. The book’s most prominent abilities include autonomous movement, opening itself, emanating light, speaking, and, most importantly, generating a time-space portal that transports individuals into the past. Through these powers, Bíblia serves as the direct link between the contemporary world of the children and the ancient world of the scriptures.
