Goku became well-known for the energetic, kindhearted, pure heart and caring personality traits he inherited from his mother Gine. He was taught to be compassionate and respectful to others by Grandpa Gohan. He takes most situations in stride; he rarely lets things get him worked up; he quickly got over losing his tail each time. Luffy's most dominant traits are his apparent lack of common sense, his utter fearlessness and unwavering belief in himself.
