Aizawa is primarily motivated by logic and does not believe in the necessity to maintain a clean-cut appearance or filter his words or ideas for others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations, preferring to take naps in his sleeping bag instead. Deku is a very determined and hardworking character. Despite not having a Quirk initially, he never gives up on his dream of becoming a hero and trains relentlessly.
