Which term describes something unusual or extreme that attracts attention?

The term that best describes something unusual or extreme that attracts attention is "striking." This word conveys a sense of being notably impressive or vivid, making it suitable for something that stands out in a significant or dramatic way. When something is striking, it captures attention due to its distinctiveness or impact, often evoking a strong emotional response or interest.

Other terms such as "remarkable" also imply something noteworthy but may not necessarily have the same immediate visual or emotional impact that "striking" suggests. "Ordinary" refers to something that's common or unremarkable, which clearly does not fit the description of attracting attention due to its unusual nature. "Disregarded" indicates something that is overlooked or ignored, which stands in contrast to attracting attention.

Thus, "striking" effectively encapsulates the idea of being unusual or extreme and the resultant attention it garners.
