BoBoiBoy is a superhero from the city but he was sent to Rintis Island to stay with his grandfather, Tok Aba. He went to school with his friends in Rintis Island Elementary School in Primary 5. When Rintis Island is under attack by villains, he will use his great BoBoiBoy Elemental Split to defeat his opponents. BoBoiBoy lives with his grandfather, Tok Aba who sells chocolate products on a mobile stall. As a superhero, he has the power to control 3 elements - Earth, Wind and Lightning. Ultimately he can split into the 3 elements, forming 3 specialized elemental heros within a limited time. BoBoiBoy is an energetic individual. A natural-born superhero and leader at heart, he works hard to protect the world, and later the whole galaxy. Overall he is shown to be very friendly and kind throughout the series. He is courageous and doesn't hesitate to jump into battle to protect other people and the ones he cares about. BoBoiBoy repeatedly has shown to risk his life more than once just for the sake of others, even risking death. Throughout the series, although he can get stressed from his superhero life, BoBoiBoy has said and shown that he is more than happy to be a superhero and is shown in Galaxy that he's eager to help out others. BoBoiBoy has a tendency to get annoyed by people or things but is good-natured at heart. Although responsible, typically shown during his time at school, he is also very playful and a bit of jokster. At times he is also a deadpan snarker, especially with Gopal's antics. Despite the heavy responsibility he has as Earth's superhero, he is still a child at heart and can easily be impressed or entertained by little things. In his spare time, he enjoys playing football and video games with his friends, especially Gopal. He has a good relationship with his parents and though enjoys his new life, he can get a little homesick sometimes. However, his urge to do good and bring justice to those who deserve it can also get in the way of his personal life. This was evident during BoBoiBoy: The Movie, where he put his work above his friends, who get cross at him for constantly doing superhero work and forgetting about planned events. However, he learns that he needs to make time for his friends as well as do superhero work. In addition to his good traits, BoBoiBoy is notoriously forgetful and sometimes can overjudge his capabilities to do certain things, but means well overall. When using his Elemental split, his different forms have noticeably different personalities, all possibly amplified components of BoBoiBoy's true persona. BoBoiBoy Lightning is short-tempered, serious and exceptionally fierce during battles (turns into a loner-type in Galaxy). BoBoiBoy Wind is the most cheerful and carefree of the original three Elements. BoBoiBoy Earth acts as the de facto leader, being the most calm, responsible, wise and calculating as the representation of BoBoiBoy's original personality. BoBoiBoy Fire is a jokester and excitable, but easily stressed and often careless (vengeful and violent in Galaxy). BoBoiBoy Water is relaxed and calm, but very lazy. BoBoiBoy Leaf is naïve, air-headed, and has a child-like nature, mostly due to BoBoiBoy hitting his head when he gained the form. BoBoiBoy Light is as serious as Lightning, if not more so. He is the most powerful Element, which lends to his main flaw of arrogance, overestimating himself and sometimes underestimating the capabilities of his teammates. The personalities of his second-tier Elements are similar to the first-tier, except that their most prominent traits have been taken to extremes. Despite their strong personalities, they are capable of working together when in battle.

You being a curious little kid who still learn how to control your shapeshift and elemental power,it made Boboiboy along with his Elemental Power kind of protective of you.
