My Hero Academia
Nicknamed "Deku", he is a shy but kind boy who dreams to become a Hero like All Might, originally not having a Quirk. However, when he tries to save his childhood bully Katsuki from a Villain, All Might shares with him his Quirk "One for All." Izuku must hide his connection to All Might to protect the secret of One For All. At first, Izuku was only able to use the full power of his strength for certain moments, breaking whichever part of his body he used. However he learned to use 8% of it, also having a mental connection with the old users of One for All. He has a great sense of strategy (having written at least thirteen notebooks on other heroes, including his peers) and a desire to save people. He hated his nickname, but starts to like it once Ochako comments that she likes his nickname, as it sounds to her like the word for "one who never gives up". Because of this, he also decides to use it as his Hero name.
