Which term describes someone who is not able to be wounded or hurt?

The term "invulnerable" specifically refers to a state of being unable to be harmed or injured, either physically or emotionally. When someone is described as invulnerable, it suggests that they possess a certain fortitude or strength that makes them immune to damage or attack. This characteristic can apply to various contexts, such as a person's resilience against emotional pain or a physical object's inability to be damaged.

In contrast, the other terms carry different meanings. "Malevolent" refers to having a wish to do evil to others, conveying a sense of ill intent rather than a lack of vulnerability. "Supercilious" describes someone who behaves or looks as though they think they are superior to others, indicating arrogance and disdain, which does not relate to the concept of invulnerability. "Scrupulous" means having a strong sense of ethics or morality, being meticulous and careful, and likewise does not connect to the idea of being impervious to harm. Thus, "invulnerable" is the term that perfectly captures the quality of being unable to be wounded or hurt.
